The basis of the algorithm Swarm Intelligence (SI) Protocol, gives idea to difficult and intelligent characteristic through simple, non centralized and unsupervised interactions between a large sheer of autonomous swarm intelligent members. The algorithm ant colony optimization algorithm is popular due to its dynamic and adaptive nature in the real time system. It is concerened mainly with ants which find the shortest routing path to food by secreting a substance called pheromone. All the other ants follow the initial ant which took the shortest path from source to destination. When a obstacle or disturbance is faced by any other ant, further finds a new shortest path from source to destination and all other ants follow the new ant.
Mobile Communication is a wireless connection between two nodes which is having limited bandwidth and high rate of data disconnnection. So there is a requirement of new MANET routing protocol having low rate message overhead. Hence it is necessary to enhancement the performance of MANET. The reduction of routing overhead decreases the usage of bandwidth of the network. The increase of bandwidth will increase the throught and decrease the latency of the nodes of the network. This Paper proposes the new Routing Protocol which will increase the throughput,reliability and decrease the latency of the network. Introduction:The mobile adhoc network[1] does not have any fixed infrastructure and base station of the network and thats why the name is used.There are many applications for ad-hoc networks like conferencing, emergency services, personal area networks, embedded computing, and sensor dust. A MANET is a network that allows direct communication of two nodes, when radio propagation conditions exist between two nodes. If there is no direct connection between the source and the sink nodes, multi-hop routing is used. In multi-hop routing, a packet is forwarded from one node to another, until it reaches the destination.A routing protocol is necessary in adhoc networks; this routing protocol has to adapt quickly to the frequent changes in the adhoc network topology. Ad-hoc routing protocols are classified into three categories. The first category is Table- AODV is a well known on-demand routing protocol where a source node initiates route discovery when it needs to communicate to a destination that doesn't have a route to it. Once a route is discovered between the two nodes, data transfer occurs through until the route broken due node movement or interference, due the erroneous nature of wireless medium. Route maintenance initiated when a route failure happens between two nodes. The upstream node of the failure tries to find a repair to the route and this process called local repair.This paper proposes a new adaptive routing protocol for MANET called AODVWLRT (AODV with Local Repair Trials).The AODVWLRT modifies the local repair algorithm used in the route maintenance of the AODV routing protocol. The AODVWLRT mainly reduces the routing message overhead resulted from the original AODV local repair algorithm. This enhancement leads to higher throughput,reliability and lower latency than the basic AODV. AODV description:AODV is a widely researched protocol among the research community. Most of research effort has focused on simulations aimed at determining the performance of AODV, and also comparison in the performance of other ad-hoc routing protocols. Currently there exist several AODV implementations that comply with a varying degree to the protocol description.
