Design of an Energy Efficient Routing Protocol for MANETs based on AODV
Mobile Ad Hoc Networks (MANETs) also called mesh
networks are self-configuring networks of mobile devices
connected by wireless links. MANETs are deployed in
situations where there is no existing infrastructure, such as
emergency search and rescue, military, etc. Each application
has a different set of requirements. In this paper we concentrate
on emergency search and rescue operations which rely heavily
on the availability of the network. The availability is a direct
cost of the overall network lifetime, i.e., energy of the nodes.
The first objective of our work is to select two
existing energy efficient routing protocols based on AODV,
each of which is based on a different energy cost metric. We
then propose the design of a protocol that is a combination of
two energy cost metrics in a single protocol. The second
objective is to evaluate the performance of the proposed
protocol against the two protocols chosen for combination and
against the traditional AODV. The performance metrics used
for evaluation are packet delivery ratio, throughput, network
lifetime and average energy consumed. The simulation will be
done using NS2 network simulator.
