| 摘 要： | 无线传感器网络中的GEAR路由协议在解决路由空洞问题时,会出现短暂路由环现象,使分组转发跳数增大,浪费更多的网络能量.基于反馈避免的思想提出一种改进的GEAR路由算法,当转发节点发现自身为空洞节点时,便向其邻节点广播hole信息,在分组转发时,邻节点将该节点标记为空洞节点,转发节点修改自身的综合代价,从而绕开该空洞节点...

| Abstract: | In wireless sensor networks,there exists routing loop phenomenon while utilizing GEAR routing protocol to solve the routing hole problem,resulting in more hop counts for packets relaying and waste more network energy.An improved GEAR routing algorithm is presented.Transmitting node broadcasts messages of hole to neighbor nodes while it is a routing hole-node.The neighbor nodes mark the hole nodes and transmitting nodes change the cost value itself,so the impact of hole nodes are avoided and routing loop pro... |
