摘要
无线体域网(WBAN)是一种在医疗领域应用广泛的现代通信技术。数据可靠性是医疗应用的关键性指标,为了保证无线体域网环境下采集的数据可靠有效,提出了一种跨层机会主义路由(CLOR)协议,该协议使用基于计时器的中继节点选择机制提高可靠性。该计时器的值由接收信号强度指示(RSSI)和剩余能量所决定。与其他可能的中继节点相比,通过CLOR选定的中继节点具有最高的剩余能量,并且更靠近汇聚节点。仿真结果表明,与简单机会主义路由(SOR)相比,CLOR协议在可靠性、能量效率、端到端(ETE)传输时延和网络生命周期方面都有了明显的提升。
Wireless Body Area Network(WBAN)is a modern communication technology widely used in medical field.Data reliability is a key performance index of medical applications.In order to ensure the reliability and effectiveness of data collected in WBAN environment,a Cross⁃Layer Opportunistic Routing(CLOR)protocol is proposed,which improves reliability by using a timer⁃based approach for the relay selection mechanism.The value of the timer depends on the Received Signal Strength Indicator(RSSI)and residual energy.Compared with other possible relay nodes,the relay node selected by CLOR will have the highest residual energy and will be closer to the sink node.The simulation results show that compared with the Simple Opportunistic Routing(SOR),the CLOR protocol improves significantly in reliability,energy efficiency,ETE(End To End)delay and network lifetime.
