Distributed Connectivity Restoration Algorithm with Optimal Repair Path in Wireless Sensor and Actor Networks

The actor nodes in wireless sensor and network (WSAN) are responsible for receiving the perceived data, processing collaborating with each other. In most scenarios, maintaining connectivity of interactor is necessary to plan optimal coordinated response. However, actors vulnerable damage due their limited energy harsh environment. At worst, such failure can split network, which affecting performance. To restore connectivity, existing methods replace failed node by selecting a redundant network. Multiple may be involved moving from node, thus forming repair path. paths generated often not optimal. this paper, we use gradient generation diffusion mechanism propose gradient-based distributed recovery (GDCR) algorithm. GDCR selects an path global based on distribution under fully localized conditions. timely respond minimize range movement overhead. Simulation results verify performance proposed
