本发明提供了WSN中面向应用的路由协议。通过对应用、节点及Qo S的参数进行标记得到基本概念,建立包含应用、节点及Qo S本体的任务本体。将路由分为任务扩散、簇头选择,任务初始化,任务协调四个阶段。任务扩散过程中节点广播所要完成的任务,节点记录邻居节点相关信息;簇头选择中,节点根据应用要求选择最优上级节点作为自身数据的接收节点;任务初始化设置每个节点所要完成的任务;任务协调调整节点间的任务分配,达到最优效果。
The present invention provides an application oriented routing protocol in WSN. The basic concepts are obtained by marking the parameters of the application, node and QoS, and the task ontology including application, node and QoS ontology is established. The routing is divided into four phases: mission diffusion, cluster head selection, task initialization and task coordination. In the process of cluster head selection, the node selects the superior superior node as the receiving node of its own data according to the application requirements. The task initialization sets the tasks to be completed by each node. Task coordination Adjust the task distribution between nodes, to achieve the best results.
