无线传感网中基于协作的连通性修复算法

In WSNs, nodes are usually deployed in harsh environment, thus nodes are highly susceptible to attack and death. And the network will be divided into several disjoint parts so that the network is not available. Therefore, how to repair the network connectivity is a fundamental problem in WSNs. This paper proposes a connectivity restoration algorithm based on cooperative transmission, also balance nodes' residual energy by adjusting the weighting factor to avoid a single node early death. The simulation results show that the proposed algorithm compared to other algorithms performance is superior. The algorithm can extend communication range and balance the node energy besides repairing connectivity.
