Location Aided Flat Hybrid Routing Protocol (LAFHRP)

Routing protocols for mobile ad hoc networks can be classified into two categories: topological routing and geographic routing. However, most of the existing protocols use only one routing strategy for different types of networks. Routing protocols that give good performance for sparse networks may not perform well in dense networks. Routing protocols that are suitable for small networks may not scale well in large networks. Due to the fact hybrid routing protocols based on the benefits of both schemes have attracted a lot of attention recently. Proposed protocol is a hybrid routing protocol that provides a hybrid solution of topological and geographic routing. The protocol is a flat routing protocol in spite of using the partitions. Incorporation of long hop routing (smaller number of longer hops) reduces the number of nodes on the route and hence also the overhead involved. It employs swarm intelligence location service to find out the location of a destination instead of exploiting the flooding, thus overcome from a number of related problems like low scalability, more overheads, energy and bandwidth usage, single point failure and network congestion. With the help of location information it forwards the packet directionally towards the destination. Copyright c © 2011 Yang’s Scientific Research Institute, LLC. All rights reserved.
