【摘要】：针对定向扩散协议中兴趣泛洪时巨大的能量开销以及最优路径后续维护等问题,提出一种无线传感器网络中基于簇头路径转换的定向扩散路由协议.该协议首先通过结合非均匀分簇将网络分簇,在兴趣扩散时将兴趣消息扩散到簇头,减少能量消耗;其次,通过在簇头之间选择优先级最高的下一跳簇头节点形成最优路径,进行后续数据的传输.直到最优路径上某个簇头所剩能量接近设定的阈值时,该簇头采用基于时间的回溯迭代查询机制选择继任的传输节点,进行最优路径的转换,继续传输数据.仿真结果表明,该协议能有效延长网络生存周期,提高能量利用率,均衡网络能量消耗.
[Abstract]:In order to solve the problems such as the huge energy cost of interest flooding in directional diffusion protocol and the following maintenance of optimal path, etc. In this paper, a new directional diffusion routing protocol based on cluster head path conversion in wireless sensor networks is proposed. Firstly, by combining non-uniform clustering, the interest message is spread to the cluster head in the case of interest diffusion, and the energy consumption is reduced. By selecting the next hopped cluster head node with the highest priority among the cluster heads to form an optimal path for subsequent data transmission, the remaining energy of a cluster head on the optimal path is close to the set threshold. The cluster head uses the time-based backtracking iterative query mechanism to select the successive transmission nodes, to convert the optimal path and continue to transmit data. The simulation results show that the proposed protocol can effectively prolong the lifetime of the network and improve the energy utilization ratio. Balanced network energy consumption.
