Abstract:
Mobile ad hoc network is a collection of the wireless mobile hosts without fixed infrastructure
and centralized administration. Communication in MANET is done via multi-hop paths and it is
mainly constrained with bandwidth, security and limited energy resource. From those constraints
energy conservation is a major issue in the ad hoc networks for saving network lifetime with lim ited battery power.
In Multipath Adhoc Ondemand Distance Vector protocol, the route discovery mechanism utilizes a
simple flooding method, where a mobile node massively rebroadcasts received route request (RREQ)
packets until a route to the destination is established. This may cause more retransmissions and
excessive energy consumption.To solve this problem in the proposed work we designed a routing
protocol that discovers route by calculating the required energy of a node to reach its neighbor node
and compared it with its residual energy for deciding whether a node can forward the RREQ or
not. After discovering routes we can select the best optimal path by considering route cost function
value.
The main aim of this work is to design an energy efficient routing mechanism based on existing
Multi-path adhoc on demand distance vector routing protocol. This method can significantly reduce
the energy consumed during route discovery and selection operation. We simulated our proposed
algorithm using the NS2 simulator and evaluated the performance of the proposed EEMAODV with
the existing MAODV protocol in terms of average energy consumption and packet delivery ratio.
Simulation results have proved that the proposed protocol is more energy efficient than the existing
MAODV protocol in terms of energy consumption and also provides a higher packet delivery ratio
than the existing MAODV protocol.
