为解决水下移动无线传感器网络(MUWSNs)存在的拓扑失效问题,考虑水流对MUWSNs网络拓扑的影响,提出一种水下移动无线传感器网络拓扑愈合算法.采用鱼群算法部署AUVs节点,建立系统的失效感知机制、消息传递机制和移动愈合方案,并在此基础上进一步设计鱼群启发的MUWSNs拓扑优化方案.通过两组仿真实验分别验证了方案的可行性和算法的有效性.实验结果显示,拓扑愈合方案可确保网络对监测事件的覆盖度维持在90%左右,且拓扑优化方案能够进一步提高网络覆盖度.
In order to solve the problem of topological failure of underwater mobile wireless sensor networks (MUWSNs) and to consider the effect of water flow on MUWSNs network topology, an algorithm for topology healing of underwater mobile wireless sensor networks (WSNs) is proposed. AUVs nodes are deployed using fish-swarm algorithm Failure perception mechanism, message delivery mechanism and mobile healing program, and on the basis of which the fish-inspired MUWSNs topology optimization scheme is further designed.The feasibility of the scheme and the effectiveness of the algorithm are verified respectively by two sets of simulation experiments.The experimental results show that, Topology healing program to ensure that the network coverage of monitoring events remained at about 90%, and topology optimization programs to further improve network coverage.
