In recent years, wireless sensor networks have been widely used in many real-life scenari-os, and have become more and more important. However, network connectivity is necessary for sensor network applications. When some of sen-sor nodes fail (due to energy depletion or de-struction), it will cause the network disconnected. How to restore network connectivity is very im-portant. Hence, in this paper we propose a Distrib-uted Coverage-based Connectivity Restoration (DCCR) which just needs a few nodes to execute critical nodes detection; coverage rate, residual energy, distance and degree are also considered to choose a backup node. Then, to promote the coverage rate, a better location is searched for a backup node to move to. Finally, the simulation results demonstrate that our proposed scheme outperforms DARA and NORAS in terms of coverage rate and residual energy.
