In wireless sensor-actor networks, the sensors sense the surroundings and transmit the sensed data to the actors. The actor nodes respond collectively to achieve their purpose. Since the actors and sensors have to communicate at all times, a strong network topology has to be established. A failure of an actor may cause the network to be broken into two. The solution can be provided by moving actor node thus restoring connectivity. Current recovery schemes consider only single node failure. This paper overcomes this shortcoming by recovering from multiple node failures through Least-Disruptive topology Repair (LeDiR) algorithm. LeDiR algorithm depends on the local view of each node about its neighbor to find the recovery plan.

Abstract


In wireless sensor-actor networks, the sensors sense the surroundings and transmit the sensed data to the actors. The actor nodes respond collectively to achieve their purpose. Since the actors and sensors have to communicate at all times, a strong network topology has to be established. A failure of an actor may cause the network to be broken into two. The solution can be provided by moving actor node thus restoring connectivity. Current recovery schemes consider only single node failure. This paper overcomes this shortcoming by recovering from multiple node failures through Least-Disruptive topology Repair (LeDiR) algorithm. LeDiR algorithm depends on the local view of each node about its neighbor to find the recovery plan.
