针对无线传感器网络中(WSNs)随Sink节点位置移动带来的网络连通、能耗等问题,提出一种采用多波束转换天线的跨层集成协议(IMRPSB),协议充分利用了多波束转换天线优势,并将MAC层与路由层层间融合。利用移动Sink节点场景模型进行仿真,结果表明:IMRPSB在保证网络连通性的同时,提高了网络的寿命,增强了网络性能。
In order to solve the problems such as connectivity and energy consumption brought by mobile Sink node in WSNs,a cross-layer integrated protocol MAC and routing protocol based on switched-multi-beam antennas( IMRPSB) is proposed,protocol takes full advantages of switched-multi-beam antennas,and fuses MAC layer and routing layer. Mobile Sink node model is used to simulate the scene,and results show that IMRPSB ensures network connectivity and at the same time improves network lifetime and strengthen performance of network.
