基站选择Sink的无线传感器网络路由协议

Routing protocol of base station selecting Sink in wireless sensor network

节点的能量标志着无线传感器网络(WSN)的生命周期,但是当前一些路由协议不能够很好地平衡、延长网络的生命周期。基于此,提出了一种基站选择Sink的无线传感器网络的路由协议。该协议利用环和边构成扇形区域,基站选择几个能量较大的节点作为扇环内的Sink,这些Sink采用TDMA的原理轮流成为当前的Sink,从而平衡整个网络的能量开销。仿真结果表明,该基站选择Sink的路由协议要比CWR协议更能节约能量、延长网络的生命周期。

The energy of node indicates the lifetime of Wireless Sensor Network （WSN）. However, some routing protocols are not so perfect to balance or extend the lifetime. Routing protocol of base station selecting Sink in WSN was proposed. This protocol used rings and edges to form the sector regions. The base station chose some nodes with larger energy as Sinks in every fan-shaped region. These Sinks selected the right Sink in turn with TDMA, and then could balance the energy of the entire network. The simulation results show that this routing protocol of base station selecting Sink can save energy, and prolong the network lifetime than CWR protocol.
