Abstract: Wireless sensor network, network lifetime plays an important role for data gathering process. In WSN, battery powered sensor nodes sense the environment at the transmission and collect the data from source node and forward to the sink node. The proposed techniques such as analytic model to increase the transmission power during routing process. The theoretically estimate the traffic load, energy consumption, and lifetime of sensor nodes during the entire network lifetime. Furthermore, we investigate the temporal and spatial evolution of energy hole and apply our analytical results to WSN routing in order to balance the energy consumption and improve the network lifetime. Extensive simulation results are provided to demonstrate the validity of the proposed analytic model in estimating the network lifetime and energy hole evolution process.
Keywords:WSN,Traffic, Energy.
