Ad Hoc网络节能路由协议研究与设计

Research on Energy-efficient Mechanism for Ad Hoc Network

对现有的Ad Hoc网络节能路由协议进行了研究,并提出基于动态源路由协议的能量感知路由协议PADSR。给出了算法的具体实现,在多条可达路由路径中,总是选择节点剩余能量最多的路径,当正发送数据的节点能量低于某一门限时,将通知邻居节点选择其它路由路径来发送数据,以避免该节点的能量过快消耗完,从整体上延长了网络生存时间。仿真表明了算法的有效性。

We focus on the research of the routing protocol which is based on energy-efficient mechanism in Ad Hoc network.We proposed Power Aware Dynamic Source Routing protocol based on Dynamic Source Routing.The energy-efficient routing algorithm nodes can not only choose the routing path with the most residual energy,but also notify neighbor nodes to choose other paths to send data when the node＇s residual energy is too low,thus to avoid its own energy to be used up in a short time,providing implementation procedure of the algorithm.The effectiveness of the algorithm through simulation was analyzed.
