Abstract
One of the challenging tasks in Mobile Ad hoc Network is to discover precise optimal routing solution due to the infrastructure-less dynamic behavior of wireless mobile nodes. Ant Colony Optimization, a swarm Intelligence technique, inspired by the foraging behaviour of ants in colonies was used in the past research works to compute the optimal path. In this paper, we propose a Recurrent Ant Colony Optimization (RECACO) that executes the actual Ant Colony Optimization iteratively based on recurrent value in order to obtain an optimal path convergence. Each iteration involves three steps: Pheromone tracking, Pheromone renewal and Node selection based on the residual energy in the mobile nodes. The novelty of our approach is the inclusion of new pheromone updating strategy in both online step-by-step pheromone renewal mode and online delayed pheromone renewal mode with the use of newly proposed metric named ELD (Energy Load Delay) based on energy, Load balancing and end-to-end delay metrics to measure the performance. RECACO is implemented using network simulator NS2.34. The implementation results show that the proposed algorithm outperforms the existing algorithms like AODV, ACO, LBE-ARAMA in terms of Energy, Delay, Packet Delivery Ratio and Network life time.

1. Introduction
M obile Ad Hoc Network [MANET] is a collection of mobile nodes that can be dynamically set up without any fixed infrastructure. It is an autonomous system in which the mobile hosts connected by wireless links are free to move randomly and often act at the same time. The topology of such network is likely to be highly dynamic because each network node can freely move and no pre-installed base station exists. Due to the limited wireless transmission range of each node, data packets may be forwarded along multi-hops. Route construction must be done with a minimum of overhead and bandwidth consumption. Energy Efficient Routing Protocols [1] are challenging to design as performance degrades due to scalability of mobile ad hoc network remains as an open challenge.
The MANET routing Protocols are categorized as proactive, reactive, flow oriented and hybrid routing Protocols [2 , 3] . Proactive Routing Protocols [4 , 5] maintain a new list of destination nodes and their routes by distributing the routing tables throughout the entire network for every periodic interval of time. The main disadvantages are maintenance of respective amount of data and slow reaction towards failures. Reactive Routing Protocols [6 - 10] find route only on-demand by flooding route request packets throughout the network. The key motivation of this protocol is the reduction in routing load and there will be an impact on the performance for low bandwidth wireless link if high routing load exists. The main disadvantages are high latency time and excessive flooding leads to clogging. Flow-Oriented Routing Protocols [11 , 12] find a route on-demand by tracking the present flows. This is achieved by unicasting consecutively while promoting a new link. The main disadvantages are it takes long time when exploring new routes without prior knowledge and may refer to estimate existing traffic to compensate for missing knowledge of routes. Hybrid Routing Protocol [13] combines the advantages of proactive and of reactive routing. The routing is initially established with some proactively prospected routes and then serves the demand from additionally activated nodes through reactive flooding. The choice for one or the other method requires predetermined for typical cases. The main disadvantages of such algorithms are reaction to traffic volume depends on number of nodes activated and the traffic demand depends on gradient of traffic volume.
Ant Colony optimization (ACO) is a meta-heuristic approach introduced by Marco in 1992 [14 - 20] . ACO Techniques that inspires the behaviour of natural ants [21 - 23] uses the computational agents as ants to determine the shortest route form from nest to food location by depositing the pheromone trails. These pheromone trails are used by the future ants towards optimal solution [24 - 26] .
Once the ants reaches the destination, it takes the reverse path to reach the destination. The pheromone intensity gets reduced in all non-optimal paths due to pheromone evaporation factor. These Swarm intelligence techniques are used for controlling unmanned vehicles, for planetary mapping [27] and solving other combinatorial optimization problems [28 - 30] . Ant-based routing algorithms have a number of properties which are desirable in MANETs: they are highly adaptive to network changes, use active path sampling, robust to agent failures, provide multipath routing, and load balancing.
Autocatalysis plays an imperative role in functioning of ACO algorithm i.e., the more the ants choose a move, the more the move is rewarded by increase in pheromone intensity, the more attention-grabbing will be for the subsequent ants [16] . The amount of pheromone deposited is made proportional to the integrity of the solution an ant has built in its building.
As a result, if a move contributed to generate a high-quality solution its integrity will be increased proportionally to its involvement. Based on this terminology we designed a modified Ant colony Optimization technique that executes the ACO recursively in order to obtain optimal convergence solution.
Rest of the paper is organized as follows: Section 2 provides the literature survey and related works with various classifications of Ant colony based routing algorithms. Section 3 describes the newly framed Recurrent Ant Colony Optimization (RECACO) with detailed contents of pheromone tracking, pheromone renewal strategy and node selection based on the residual energy in the neighbor nodes. Section 4 describes the formulation of combined metric ELD (Energy Load Delay) for performance evaluation. Section 5 concludes the paper.
2. Related Works
ACO based Routing Protocols are classified as Table Driven or Proactive Ant based Routing Protocols, On-Demand or Reactive Ant based Routing Protocols and Hybrid Routing Ant based Protocols.
- 2.1 Table Driven or Proactive ant based Routing Protocols
- 2.1.1 Ant Based Control (ABC)
ABC scheme is proposed for routing in telephone network [31 - 33] and the network performance depends on the capacity to attend the calls. Thus ABC routing is a circuit switched routing and is merely proactive. It is appropriate for mobile ad hoc networks due to their decentralised nature, high robustness to node failures and load balancing and adaptability to highly dynamic environments. In ABC, the ants adapt the following procedure. The source node releases a group of exploratory ants. Node choice is probabilistic and route selection is deterministic. Each node maintains a routing table that contains a list of neighbor and all possible destinations that can be reached for that particular node. The amount of pheromone deposited modifies the routing table. Aging and decaying of ants are the new features of ABC. An artificial delay is incorporated in order to reduce the agents entering into congested link. Thus ABC algorithm has less failure compared to other methods [34] .
- 2.1.2 Probabilistic Ant Routing (PAR)
PAR [35 , 36] adopts both unicast and broadcasting of ants to search path towards destination. When the route to destination is available then unicasting of ant is adopted or else the ants are broadcasted. The Forward ant pushes the node ID and node traversal time in each intermediate node it visits. When the forward node reaches the destination, it transfers all the route information to Backward ant and dies. The Backward ant utilizes this information to reach the source node.
- 2.1.3 AntNet
In AntNet, the ants adopt the following protocols [37 , 38] : The source node periodically generates Forward ants and the link selections are based on the probability value which is the function of queue length. At each intermediate node, the ant stores the node ID of the previously visited node and time stamp in a buffer. When the Forward ant reaches the destination, it becomes the backward ant and takes the reverse route to reach the source. The Backward ant updates the link probability at each node during its reverse transit to source.

Analysis of ACO Algorithms
- 2.2 On-Demand or Reactive ant based Routing protocols
- 2.2.1 PACONET
PACONET is an improvised ant colony optimization algorithm for MANETs. PACONET [30 , 39 , 40] ensures that all possible paths from a particular node have been traversed. The Forward ant takes the next hop node to be the unvisited node based on the pheromone concentration. The routing table maintains a binary value for each node that indicates whether the node has been visited or not and the pheromone concentration value for the corresponding node pair.
- 2.2.2 Probabilistic Emergent Routing Algorithm (PERA)
Whenever the route to destination is unavailable, the source node broadcasts the forward ant with unique sequence number to all the neighbor nodes [40 - 42] . The forward ant selects the link based on the probabilistic distribution available on the routing table. The routing table at each intermediate node contains the records with the following information that is updated by the Forward ants. The IP address of the source node and destination node, unique sequence number, hop count and a dynamic stack that contains the route traversed and the timestamp that indicates the time the forward ant traverse the particular intermediate node. Here both the forward and the backward ants are broadcasted and that leads to network congestion and unnecessary energy consumption. The multiple routes to destination will be available in the routing table when the backward ant reaches the source node. The source node selects the path with higher probability to transmit the data packets. The other optional path may be used during the occurrence of link failures.
- 2.2.3 Ant Dynamic Source Routing (ADSR)
ADSR [43 , 44] is similar to that of DSR but for the route request and route reply, the forward and backward packets are added and are used during route discovery process.
- 2.2.4 Ant colony based Routing Algorithm (ARA)
ARA works in three phases [45 - 47] : Route Discovery Phase, Route Maintenance Phase, Route Failure handling. In the Route Discovery phases, the source node broadcast the Forward ants to all its neighbors. Each Forward ant has a unique sequence number using which duplication is avoided. Forward ants while reaching each intermediate node, create a record in its routing table with the entries as destination address, next hop node and pheromone value. Once the forward ant reaches the destination node, it extracts the information from forward ant and destroys it. Then the Destination node creates a backward ant and sends it to the source node in the reverse path. In route maintenance phase the data packets are relayed from source to destination through the intermediate node and pheromone updating keeps on increasing. The same happens when the data packets are delayed in the opposite direction. In route Failure handling phase, the link failure is detected by the source through missing acknowledgement and the failed link is eliminated by resetting the pheromone value to zero. In ARA, the new route discovery actions are never initiated unless and otherwise the source receives any route error message notification.
- 2.3 Hybrid ant based Routing Protocols
- 2.3.1 AntHocNet
The Route discovery [48 - 50] adapts the following procedure: When a node is in need of packet transmission, it checks its routing table whether information to reach the destination is available. If yes, it unicasts the packet and if not, it broadcasts the F-ants to its entire neighbor. Once an intermediate node receives F-ant, it checks whether route to destination is available through any of its neighboring node. If so, it unicasts the F_ant. If not again the F-ant is broadcasted to the entire intermediate node. The procedure is iterated till a path to destination is determined. Once the F-ant reaches the destination, it becomes B_ant. The destination node discards the duplicate F-ants. The B_ants travels in the reverse path updating the routing table at each intermediate node. Link failure is detected with the help of timer.
- 2.3.2 Ant Routing Algorithm for MANET based on Adaptive Improvement (ARAII)
ARAII maintains two routing table: 1. The routing table in each intermediate node is maintained with the following information: Initial node, Last node and heuristic value. Here the Initial node represents the initial leaving place of ants; last node represents the address of previous s intermediate node and heuristic value energy information of the intermediate node. 2. The routing table that contains neighbour information with the following columns: neighbor, pheromone, time. The neighbor column to store all the neighbor node of a current node, pheromone column maintains the link reliability and time is component to monitor the connectivity between the nodes. During path establishment, the Forward ants chooses the next node randomly that is biased by the pheromone value and local heuristic value of the edge between two nodes.
- 2.3.3 Multi-Agent Ant based Routing Algorithm ( MAARA)
MAARA [51 , 52] involves five phases: Route discovery, Route updating, Data routing, Route maintenance and Route failure handling. In MAARA, each node maintains a routing table (proactive) and the route discovery phase is initiated only when there is demand for transmission. The Forward ant with source address and unique sequence number is broadcasted by the source. Thus duplication is avoided. The first ant that reaches the destination becomes backward ant and it takes the reverse path to reach the source node. The backward ant updates the destination address, hop count and pheromone value. Data packets are transmitted based on the pheromone value in the routing table. If multiple paths to destination exist, the next hop is chosen randomly with some probability. In MAARA load balancing is achieved but it faces higher congestion that lead to high average end-to-end delay.
3. Unsupervised Clustering Design of Recurrent Ant Colony optimization (RECACO) Algorithm
Applying ACO recursively introduces an additional term profundity that decides the value of recurrent to obtain a precise optimal solution. REACO runs the actual ACO with the following three steps in each iteration: Pheromone Tracking, Pheromone Updating and Node Selection. RECACO involves four steps: Dawn of route, Route modernization, Data Steering and Route Failure Handling. Design of RECACO is shown in Table 1 and the notations used are shown in Table 2 .

Notations Used
- 3.1 Dawn of route
- 3.1.1 Generation of ACO Feasible Solution
RECACO algorithm constructs two computational agents’ namely forward ant 〈F ant 〉 and backward ant ant 〈B ant 〉 . These 〈F ant 〉 and 〈B ant 〉 agents work in two modes: FMode and BMode, respectively. Agents are in FMode when they are in transit from nest location to food location and agents are in BMode when they are in transit from food location to nest location. Once 〈F ant 〉 FMode reaches its destination, it switches to BMode and travels back
to the nest location. Agents in FMode construct a solution by choosing the next hop node among the neighbor nodes by implementing a probabilistic choice that is biased by the pheromone trails deposited by 〈F ant 〉 and 〈B ant 〉 agents in FMode and BMode respectively.
〈F ant 〉 memorises the path and when it reaches the destination it changes to BMode. 〈B ant 〉 agents in BMode leaves pheromone trails on the reverse path where it transits. This procedure eliminates the formation of loop in the path from destination to source.
Source node S will not broadcast the 〈F ant 〉 agents to the entire neighbor node. Instead it will send the 〈F ant 〉 only to the neighbor nodes whose energy level is greater than the threshold value. This threshold value represents the minimum energy required to transmit a single data packet. This procedure is iterated through all the possible paths to reach the destination. Again from the destination, the 〈B ant 〉 will take the reverse path to reach the source. When one of the 〈B ant 〉 agents reaches the source S, the recurrent value is decremented. Here the path establishment is done not based on the first 〈B ant 〉 agent received at S. The procedure is iterated till the recurrent value becomes zero. So the source node S will receive multiple 〈B ant 〉 agents. Then it selects the path among all possible paths based on the,
1. pheromone intensity
2. Probability choice
3. Energy level of the node in the path from S to D
The node with energy less than the threshold value will not be involved in the path finding and it will enter into sleep mode in order to conserve its energy for its local routing purpose. These kinds of nodes in sleep mode may be involved or may become active if and only if there are no other possible paths to reach the destination.

- 3.1.3 Pheromone Renewal
The amount of pheromone deposited is made proportional to the goodness of the solution an ant is building. So, pheromone renewal is done under two modes. Online step-by-step Pheromone renewal mode and Online delayed pheromone renewal mode. In Online step-by-step Pheromone renewal mode, 〈F ant 〉 ants release pheromone while building the solution. In Online delayed pheromone renewal mode 〈B ant 〉 , ants update the pheromone and builds the solution towards the source S. The pheromone is updated based on the formulation,

l is the pheromone evaporation rate. Pheromone evaporation is needed to avoid a too rapid convergence of the algorithm toward a sub-optimal region. Δτ is the amount of pheromone deposited by the 〈F ant 〉 ants during online step-by-step pheromone mode and by the 〈B ant 〉 in online delayed pheromone mode.

Where L k is the cost of k th ant’s tour. Since pheromone updating is done both in online step-to-step and online delayed pheromone mode, the pheromone evaporation rate will be minimum compared to other ACO optimization algorithms.

The pheromone decay factor chosen is an exponential decay factor that depends on link usage.

During the occurrence of link break, ants can take the next feasible path based on the pheromone intensity.
- 3.1.5 Daemon updates (optional)
Offline pheromone Update: the daemon can observe the path found by each ant in the colony and choose to deposit extra pheromone on the components used by the ant that build the best solution. Pheromone updates performed by the daemon are called offline pheromone updates.
- 3.2 Route Modernization
Each 〈F ant 〉 agent maintains a routing table that contains information like source IP address, Destination IP address, number of neighbor nodes visited, Energy level of each neighbor node, Pheromone intensity of each edge, probability choice value for edge selection and threshold value. Each 〈F ant 〉 updates the values in the routing table maintained at each node when it is taking its traversal from source S to destination D. When the 〈F ant 〉 agent reaches the destination, the information is transferred to 〈B ant 〉 agent from 〈F ant 〉 agent. The destination kills the 〈F ant 〉 agent and now the 〈B ant 〉 agent takes its traversal from source S to destination D updating the routing table at each node.
- 3.3 Data Steering
Data packets are forwarded based on the pheromone intensity, probability value for edge selection and energy level of the individual node in the path from S to D. The optimal path can be chosen based on the above three parameters. This can be compared in order to find the precise optimal solution from source S to destination D.
- 3.4 Route failure Handling
If any of the neighbor nodes detects link failure, it will check the routing table to find the next available path to destination D. If no path is available it will send an error message back to the source. The source node S initiates the retransmission on if it receives error messages.

- 4.5 Average End-to-End Delay
The average end-to-end delay measured against data rate using AODV. ACO, LBE-ARAMA [53] and recurrent ant colony optimization algorithm is shown in Fig. 2 . In ACO, delay increases rapidly when the packets transmitted per second increase i.e at a data rate of 8 pkts/s. In LBE-ARAMA, the delay increases smoothly when the data rate increases. But the results of the proposed algorithm shows that when the nodes determine the shortest path based on the pheromone deposit and pheromone evaporation co-efficient by executing the ant colony optimization recursively, the increase delay component is less compared to the existing algorithm. From the simulation results with respect to this end-to-end delay component we would be able to implement that proposed algorithm in real time network application that composed of very large number of mobile nodes.

The packet delivery ratio is plotted against data rate for AODV, ACO, LBE-ARAMA and recurrent ant colony optimization algorithm as shown in Fig. 3 . From Fig. 2 , it is clear that queue delay in AODV, ACO, LBE-ARAMA is high that results in increase in packet drop. As the rate of dropping of packets increase in LBE-ARAMA [53] the packet delivery ratio which is ratio of number of packets delivered at the destination node to the number packets transmitted by the source node is high compared to the proposed algorithm. Therefore, with respect to packet delivery ratio component the recursive ant colony optimization simulates better results.

This proposal satisfies multiple metrics like end-to-end delay, energy and load balancing. The innovative factors used for the newly designed algorithm is the renewal of pheromone during online step-by-step pheromone renewal mode and online delayed pheromone mode and Node selection is based on the pheromone intensity, probability choice value for edge selection, residual energy of the neighbor nodes and pheromone evaporation co-efficient factors. Various Simulation operations have been done to present the goodness of the recurrent ant colony optimization against various existing algorithms.
