摘要：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.
