Hybrid Routing Protocol in MANET using Clustering Approach

Abstract

This paper introduces the concept of Cluster Based Hybrid Routing protocol(CBHRP) in Mobile Ad-hoc Networks (MANET). Energy conservation is the main parameter to be considered in MANET. In our  work, attempt is made to achieve energy efficiency by clustering and hybrid routing. The MANET is first divided into clusters and then cluster head is elected such that its energy level and signal strength is maintained above some pre defined threshold value. The head selection and its maintenance is done using the Signal and Energy Efficient Clustering(SEEC) algorithm. Once head is selected, routing is carried out such that inter cluster routing is done using reactive protocol, where as intra cluster communication takes place using pro active protocol. Hence the name cluster based hybrid routing protocol. Simulation results show that considerable energy efficiency is achieved using clustering and hybrid routing.
