A Performance Analysis of Energy Efficient Routing In Mobile Ad Hoc Networks

A mobile ad hoc network is characterized by constraints such as limited bandwidth, energy constraints, less memory and processing capabilities. Also MANET’s are required to be deployed under scalable conditions for some applications. A routing protocol is a central to the design of such networks. In this paper we compare the energy conservation of proactive routing protocols like DSR and AODV. As DSR is a multipath source based aggressive cache routing, it has some advantages in terms of energy savings. AODV is a more robust protocol and we complement its energy conservation by integrating cross-layer energy saving extensions i.e. SPAN. Thus we would like to analyze whether energy based extensions can contribute in supporting a robust routing protocol by reducing the energy consumption of mobile nodes for improved network survivability. Also we analyze the energy conservation of nodes under scalable conditions and for different traffic patterns.
