基于轮作的无线传感网络链式路由协议

Rotation-Based WSN Chain Routing Protocol

为了节省无线传感器节点能耗,延长无线传感网络的生存周期,提出一种基于轮流作业策略的RPB无线传感网络链式节能路由协议。该协议基于PEGASIS链式协议并结合GAF协议进行改进。仿真结果显示,在保证有较高网络覆盖度的前提下,相较于传统的无线传感网络PEGASIS、LEACH和EEPB等路由协议,RPB协议在节能上更为突出,且在传感节点死亡超过总数的一半时,能实现节点在网络中较为均匀的分布。

In this paper a rotation and PEGASIS-based energy-efficient chain routing protocol is proposed to reduce energy consumption in wireless sensor nodes and prolong the life span of wireless sensor networks （WSNs）. The proposed protocol is an improved protocol of geographical adaptive fidelity （GAF） protocol based on （power-efficient gathering in sensor information system, PEGASIS） chain protocol. Simulation results demonstrate that the proposed protocol has better performance in energy conservation than traditional routing protocols, such as PEGASIS, LEACH and EEPB. Moreover, more uniform distribution of the wireless sensor nodes could be realized when more than a half of the sensor nodes died.
