| 摘 要： | 环状分层路由协议(RHR),解决了传统分层协议下簇头容易失效、簇头与Sink节点单跳传输耗能过大、传感器网络对簇头的依赖性过强等问题。但经过研究发现RHR环状协议在数据传输过程中,由于大量节点长时间处在空闲监听状态,导致过多的能量浪费和节点的过早死亡。已经证实,节点在空闲监听状态和接收状态耗能接近,所以节点在空闲监听状态下的耗能不容忽视,而避免空闲监听的有效手段就是在没有业务的情况下最大限度地关闭收/发信机。文章基于RHR协议引入休眠机制,提出了一种改进的环状分层路由协议(S-RHR),以达到减少监听能量消耗的目的。经过验证,这种协议在高密度的无线传感器网络中能够更加有效的降低节点耗能,延长网络的生存时间。

| Abstract: | Ring-based hierarchy routing protocol(RHR) has solved some problems in traditional flat protocol,such as cluster heads failure-oriented,large energy consumption by the single-hop communication between cluster heads and the sink,and strong dependence on cluster heads.But in the data transmission,there are so many key nodes in an idle listening state for long time that too much energy is wasted.It has been confirmed that the energy consumption in an idle listening state is the same as the enegry consumption i... |
