| With the development of wireless communication systems and microelectronics, WSNs have been widely used in various fields. But the survival time is still the main factor restricting the development of wireless sensor networks. In this paper, we focus on the problem of redundant data in the source node, in order to solve the energy consumption problem. Based on the TEEN routing protocol, a novel data aggregation of source node based on the TEEN protocol is proposed by analyzing the energy consumption of the network, and we use a Kalman filter to reduce the data forwarding of the source nodes. Simulation results show that the proposed algorithm can effectively reduce the data from the source node, save network energy and prolong the network lifetime.????? |
