An Application Based Fault Detection and Restoration Algorithm for Wireless Sensor Actor Networks

Wireless Sensor and Actor Networks (WSANs) is a bunch of sensors and actors joined by wireless medium to perform distributed sensing and exploit tasks. In such a network, sensors gather data concerning the physical world, whereas actors take choices and so perform acceptable actions upon the surroundings that permit remote, machine-controlled interaction with the surroundings.       Actors sometimes coordinate their motion in order that they keep approachable to every different. However, a failure of associate actor might cause the network to partition into disjoint blocks and would therefore violate such a property demand.       In this paper, a Least-Disruptive topology Repair (LeDiR) algorithmic rule [15] is presented. LeDiR may be a localized and distributed algorithmic rule [12] that leverages existing route discovery activities within the network and imposes no extra pre-failure communication overhead.
