Bottleneck Nodesare those connecting two or more isolated areas because of the random deployment.Compared with other nodes,these nodes are more important to the lifetime of the whole network.The paper proposed a distributed cascading movement solution.This solution can reduce the distance and save the energy by moving nodes,and it also reduced the time to initialize the network coverage.The solution can balance the network's communications and increase the network's lifetime by moving some nodes to its proximity.The simulation results verify that the proposed solution outperforms others in terms of network lifetime,energy consumption and the time of node relocation.
