| 摘 要： | 针对无线传感器网络中由于衰落信道等原因导致存在大量不可靠的链路,定义了机会节点集,在机会节点集里的节点可以协助完成数据的发送任务.机会节点集的协助机制,一方面利用无线传感网络的节点冗余度大,从而存在节点来协作;另一方面利用了无线信道的广播特性,从而使节点有机会来协助.定义了协助增益来评价协作机制带来的好处,推导出了解析表达式.基于机会节点集的协作机制可以用在大部分现有的路由协议中.仿真表明,采用协作机制后带来的协作增益可达1.18.

| Abstract: | Different opportunistic routing protocols have been proposed recently for routing in sensor networks.In this paper,a new opportunistic node set is proposed to coordinate the packet transmission,which takes advantage of the characteristic of wireless and the redundancy among nodes.It is based on static routing structure other than the traditional opportunistic routing by using a node that is available for routing at the time of packet transmission.Based on opportunistic node set coordination mechanism(ONSCM)... |
