摘要: 针对无线传感器网络(WSN)中节点分布不均和能量消耗较大的问题,提出一种面向特定区域的WSN组播路由协议。采用组头轮换机制,使能量储备较多和位置最优的节点担任组播节点承担转发任务,能量储备较少的节点负责数据采集任务。利用多转发组的模式建立稳定路由,提高网络健壮性,降低数据延迟。仿真结果表明,该协议可使整个区域内节点能量消耗达到均衡,从而延长区域网络的生存时间。

Abstract: For the uneven distribution and high-energy consumption problems of Wireless Sensor Network(WSN), this paper proposes a region-specific multicast routing protocol for WSN. The use of group head rotation mechanism, node with more energy reserves and the optimal location forward packets to other nodes, node with less energy reserves is responsible for data acquisition. Using multi-mode forwarding group to establish a stable route, improve network robustness and reduce data latency. Simulation results show that the agreement will achieve a balance of energy consumption and extend the network lifetime.

Key words: Wireless Sensor Network(WSN), region multicast, network multicast, routing protocol, energy consumption
