A Review on Ant Based Routing Protocols for Manet

Due to the dynamic nature of MANETs, route maintenance is quite difficult task. Routing is the process by which we choose paths in a network along which the source can send data packets towards destination. It is an important aspect of network communication because the characteristics like reliability, throughput, and congestion depends upon the routing information. An ideal routing algorithm is one which is able to deliver the packet to its destination with minimum amount of delay and network overhead. The nodes update the routing tables by exchanging routing information between the other node in the network. The ACO meta heuristic is based on generic problem representation and the definition of the ant's behaviour. ACO is based on the foraging behaviour of real ants. Main objective of this review is to study various ant based routing protocols for MANETs.
