Performance Improvement in WSN by Using Hybrid Protocol

Abstract

Efficiency of energy is an important factor in wireless network where nodes depends upon on
limited power and computational energy resource. Ad hoc on demand distance vector routing
protocol has been specially designed for mobile ad hoc networks by reducing the overhead.
So, as it can control the network wide broadcast of the RREQs (routing request) the source
node uses some kind of important technique. For increasing the lifetime of the nodes uses in
given wireless network n number of energy efficient protocols have been design such as
AODV, DSR and DSDV. We are going to propose an energy efficient route discovery method
for AODV HPR (High Power Route) Protocol using NS2. Our aim is to saves energy of the
nodes by avoiding the redundant rebroadcasting of the route request packets. The relaying
status of the node is decided based on the broadcasting of its RREQ packets by its neighbor
and it helps in reducing routing overhead incurred during the route discovery process.
