摘要: 针对无线传感器网络选择恰当的路由路径对节省节点能量的重要性,分析无线传感器网络单跳与多跳路由路径的能量消耗情况,发现数据压缩或融合时,对于给定的不同压缩或融合比存在一个不同的临界距离,当大于这个临界距离时,选择多跳路由比单跳路由更节省能量,反之则选择单跳路由比多跳路由更节省能量。仿真结果显示该文的分析是正确的,这对无线传感器网络选择路由路径具有实际的指导意义。

Abstract: To select routing line is very important to save energy in wireless sensor networks. This paper investigates the energy consumption of single-hop and multi-hop routing in wireless sensor networks, and a critical distance is found, under the condition of specified compression ratio or fusion ratio. Multi-hop routing consumes less energy than single-hop routing when the distance transmitting data from node to clustering-heads or base station is no less than the critical distance. The simulation results show analysis done is right and it has application significance to select routing line in wireless sensor networks.

Key words: wireless sensor network, single-hop routing, multi-hop routing, selectivity
