本发明首先提供一种新的无线传感器网络中的K-覆盖判定算法;随后将节点剩余能量引入覆盖调度中,考虑节点的剩余能量,提供一种新的分布式K-覆盖调度算法;通过节点能耗关系提供了综合分布式K-覆盖调度与路由的跨层设计方法,并具体提供了一种新的综合K-覆盖调度的定向扩散路由协议。在新的定向扩散路由协议的梯度调整过程中,加入了节点覆盖程度参数,增大了覆盖冗余度大的节点作为中间转发节点的概率,进一步平衡节点的能耗。仿真结果显示,新的跨层定向扩散路由协议的能耗远低于原来的定向扩散路由协议,以及与典型调度算法相结合的定向扩散路由协议。
The present invention firstly provides a K-coverage decision algorithm in a new wireless sensor network; then introduces the residual energy of the node into the coverage scheduling and provides a new distributed K-coverage scheduling algorithm considering the residual energy of the node; The energy consumption relation provides a cross-layer design method of integrated distributed K-coverage scheduling and routing, and provides a new directional diffusion routing protocol with integrated K-coverage scheduling. In the process of gradient adjustment of the new directed diffusion routing protocol, node coverage degree parameters are added, which increases the probability of nodes with large coverage redundancy as intermediate forwarding nodes and further balances node energy consumption. The simulation results show that the energy consumption of the new cross-layer directional diffusion routing protocol is far lower than the original directional diffusion routing protocol and the directional diffusion routing protocol combined with the typical scheduling algorithm.
