摘要：

由于传感节点能量供应受限,为延长无线传感网络(wireless sensor networks,WSNs)寿命,提出基于能量消耗率的节点位置对调(energy consumption ratio-based node rotation,ECRNR)方案。ECRNR方案将能量消耗率高的传感节点位置由多个传感节点轮流驻守,即由多个传感节点一起分担任务,避免由单一传感节点独自承担繁重任务而能量过早耗尽。仿真结果表明:提出的ECRNR方案能够有效提高网络寿命,与传统的方案相比,网络寿命得到有效提高。

Abstract: Limited energy supplies have made the extension of network lifetime one of the technical challenges for wireless sensor networks(WSNs). Therefore, an energy consumption ratio-based node rotation(ECRNR) scheme has been proposed in this paper. The purpose of this scheme is to allocate more sensor nodes at the positions of high energy consumption in turns, that is to say, the relay information is shared by more than one sensor nodes to avoid early energy consumption. Simulation results show that the scheme has prolonged the lifetime of networks a lot compared with traditional schemes.
