| Abstract: | A linear systematic network model is constructed based on the lifetime of sensors which will prolong network lifetime in the light of the features of wireless sensor networks.To avoid network paralysis when lapses happen on senoors,a dynamic routing algorithms is brought up to facilitate to receive information.Simulation analysis shows that retransmission model can effectively extend network lifetime,increase the amount of information collected by the network and improve the energy efficiency of the sensor networks. |
