UWSNs漏洞修复UHRA算法

An Algorithm of Underwater Wireless Sensor Networks Hole Repair

UWSNs节点分布不均匀、易被水生生物碰触,会生成直接影响网络健壮性的覆盖漏洞。针对这一问题,提出保持网络连通的UWSNs漏洞修复算法(UWSNs Hole Repair Algorithm,UHRA),UHRA依靠受虚拟力驱动的节点来修复漏洞以恢复拓扑结构及系统性能。仿真结果证明,UHRA可使已有漏洞得以修复,并得到较稳定的拓扑结构,从而延长网络生命周期。

UWSNs nodes are unevenly distributed and easily touched by aquatic organisms,which will generate coverage loopholes that directly affect the robustness of the network.Aiming at this problem,UWSNs Hole Repair Algorithm(UHRA)is proposed to maintain network connectivity.UHRA relies on nodes driven by virtual forces to repair coverage holes and to restore topology as well as system performance.The simulation results show that the algorithm can repair the existing coverage holes and obtain a more stable topology,thereby prolonging the network life cycle.
