扩散受限的多层次能量路由

Restricted diffusion multi-level energy routing

对无线传感器网络路由协议进行了深入的研究,以定向扩散路由为研究对象,提出一种扩散受限的多层次能量路由算法(RDMER);在路由的建立阶段应用分簇的思想把兴趣和探测数据的扩散限制在簇头和临界点之间;梯度的建立过程中充分考虑节点的发送消耗和剩余能量,建立了基于能量的优先级路由。经OMNeT++仿真表明:该算法较定向扩散有效降低了平均能量消耗,显著延长了网络的存活时间。

Routing protocols of wireless sensor networks（WSNs）is studied. Directional diffusion muting is taken as object of study. Restricted diffusion multi-level energy routing（RDMER） algorithm is presented. In the phase of the establishment of routing, we utilize the idea of clustering to limit the diffusion of the interests and exploratory data between clusters and borders ; during the process of setting up gradient, we take full account of the node＇ s sending consumption and remaining energy, establish muting based on the priority of energy. OMNeT ＋ ＋ simulation show that this algorithm reduces the average energy consumption more effectively than directed diffusion and increases significantly the survival time of the network.
