Wireless sensor network(WSN)that operates unattended in harsh environments may suffer from large scale damage,which makes data unable to be transmitted to the Sink nodes,hence the WSN is unavailable.To deal with the problem,a scheme is designed to restore the network connectivity by using mobile data collector(MDC).Firstly,the scheme roughly divides the nodes that remain available into K clusters by FCM clustering algorithm.Then,Dijkstra algorithm is used to minimize the MDC′s travel distance in the case of a smooth communication within the clusters.So the connectivity is restored under the MDC′s optimal path forms.Simulation experiments on a 100-node WSN confirm the effectiveness of the proposed scheme.
