Coordination-Assisted Connectivity Recovery Approach in Wireless Sensor and Actor Networks
Wireless sensor and actor networks (WSANs) can be considered as a combination of sensor network and actor network in which powerful and mobile actor nodes can perform application specific actions based on the received data from the sensors. As most of these actions are performed collaboratively among the actors, so the connected inter-actor network is important to the effectiveness of WSANs. However, such connectivity can be lost due to the failure of actors. To handle this connectivity problem, we present a distributed scheme CCRA to detect possible broken connectivity, and then restore the network connectivity through relocation of actors. The effectiveness of CCRA is validated through simulation experiments.
