Abstract: Based on the analysis of energy consumption caused by different forces inside network and the influences of different routing algorithms on the net lifetime circle,a method was proposed to extend the net lifetime circle by changing the density distribution of net energy distribution, under the circumstances of linear uniform distributed wireless sensor networks. An energy distribution model was concluded, which can be extended to a narrow strip case. The simulation results show that the lifetime circle of network is extended when the energy is distributed as this model.
