Abstract:
In this paper, the operating principle of SEP in wireless sensor networks (WSNs) is analyzed, and a multi-hop routing scheme (MH-SEP) is proposed based on different spatial density of nodes. The network is to be divided into different sizes of areas according to the multi-hop routing scheme, the cluster heads use multi-hop mode of communication to send their data to the base station considering the heterogeneous of networks. This paper mainly analysis the performance of scheme based on different spatial density of nodes. The simulation shows that the advantage of the new scheme. On the one hand, with the increase of the monitoring area, the space density decreases, the advantage of the MH-SEP is more and more obvious, comparing with SEP, on the other hand, greater size of surveillance area and smaller the density of the network is, the more obvious improvement is made from the new scheme.
