无线多媒体传感器网络高效快速恢复路由协议

Energy Efficient and Fast Recovery Routing Protocol for Wireless Multimedia Sensor Networks

无线多媒体传感器用途广泛,但往往由于部署在陌生的环境中,容易造成传感器工作不稳定甚至失效.因此本文提出了一种用于无线多媒体传感器网络的高效快速恢复协议,它以目的路由的方式,通过有选择地转发RREQs,有效减少路由建立开销并高效地完成路由寻找.每个节点都建立了多条到SINK节点的路径,当节点失效时,立即从另外一条路径转发数据,避免重新建立路由开销.仿真实验表明,本算法增加了网络的稳定性和延长网络生存时间.

Wireless multimedia sensor are widespread use in many areas, but it often be deployed or become invalid in an unfamiliar environment, so it is easy to cause instability and even failure of the sensor networks. Therefore propose an energy efficient and fast recovery routing protocol for Wireless multimedia sensor networks, multipath was established according to destination routing approach. By selectively forwarding RREQs, it effectively reduces the routing overhead and efficient completion of the establishment of route finding. Each node has established a number of paths to SINK, when the node fails, immediately forward data from another path, to avoid re-establish the routing overhead, thus increasing the stability of the network and extend network lifetime.
