Impact of CBR Traffic on Energy Consumption in MANET

Mobile Ad hoc networks (MANETs) are power constrained since nodes are operated with limited battery supply. If a battery of the node drains, its ability to forward the traffic gets affected results in reduced network lifetime. There has been considerable progress in the battery technology, but not in par with the semiconductor technology. There are various techniques adopt different approach to achieve energy efficiency. The proposed approach uses a cost metric for path selection, which is a function of residual battery and current traffic load at a node. The simulation has been carried out using QualNet simulator. The performance is based on average energy consumption for varying CBR applications.
