【摘要】 传统基于移动Sink的无线传感器网络(WSN)路由协议,在Sink移动过程中需时时散播位置信息,能耗开销巨大。针对该问题提出一种基于预测路由机制的移动Sink WSN任播路由协议(ARPMS)。在ARPMS中,Sink只在移动速度或方向发生改变时才需散播其移动信息,而传感器节点可以计算(预测)Sink的当前和将来位置并选择能耗效率最高的Sink作为任播目标。Sink由于无需时时散播其位置信息,因此节省大量能耗开销。仿真实验数据表明,相比于ALURP协议,ARPMS在能耗效率上性能更佳(223%~462%)。更多还原

【Abstract】 Traditional routing protocols for mobile sinks in wireless sensor networks,should broadcast repeatedly their current location information to all sensor nodes while sinks are moving,but this process consumes a large amount of energy.For the problem above,an anycast routing protocol for mobile sinks in wireless sensor networks(ARPMS)based on predictive strategy was proposed.In ARPMS,sinks spread their moving information only when sinks change their moving direction or speed,by those moving information,sensor nodes could calculate(predict)sinks’ current and future location and select the sink with highest energy efficiency as the anycast objective.Because sinks don’t spread their moving information at all times,ARPMS saves much energy cost.Simulation experiments results show that compared with ALURP protocol,the performance of ARPMS is better in term of energy efficiency(223%~462%).更多还原
