摘要:
针对应急环境中的灾难发生特点和救援工作要求,提出了一种无线传感网移动节点接入和定向扩散路由方法.首先设计了一种基于竞争型MAC协议的移动节点接入和链路维护机制,对定向扩散协议的兴趣扩散算法和兴趣封装进行了改进;然后,基于这种兴趣有效传播路径判定规则,建立和维护动态链路.仿真实验结果表明,移动节点的接入方法高效可靠,所用的接入机制在节点能量消耗、信号传输延时和网络吞吐量等方面都具有明显优势.采用兴趣有效传播路径判定规则的定向扩散路由算法只在局部网络内进行兴趣的准确扩散,转发的兴趣报文数量较少,且随着传感器节点总数的增多,兴趣报文数量的变化较小.
Abstract:
For disaster characteristics and rescue operation requirements in emergency circumstances, a mobile node access and directed diffusion route method of wireless sensor networks is proposed. First, a mobile node access and link maintenance mechanism based on the competitive medium access control(MAC)protocol is designed to improve the interest diffusion algorithm and interest encapsulation of the directed diffusion(DD)agreement. Then, based on the decision rule for effective paths of interest propagation, dynamic links are built and maintained. The simulation results show that the mobile node access method has high efficiency. The access mechanism exhibits advantages in node energy consumption, signal transmission delay and network throughput. The directed diffusion routing algorithm based on the decision rule for effective paths of interest propagation can only accurately spread in interest within the local network. The number of the forwarded interest packets is small, and with the increase in the total number of sensor nodes, the variation of the number is small.
