Simulation for Energy Expenditure Estimation of WSN for Comparison of Network Routing Protocols

The low power wireless communication technology has enabled the development of next generation low cost wireless sensor network. One important performance index of routing mechanism in sensor networks is sensor life span. How we utilize limited energy in wireless sensor network, directly affects the lifetime and cost of the network. As sensors are energy constrained by batteries and located for away from the access point. A sensor dies if its battery dies. Since the radio transmission consumes a lot of energy, we propose network routing protocols to save energy to prolong the sensor lifespan.
