Application-Oriented Fault Detection and Recovery Algorithm For Wireless Sensor and Actor Networks

Recent years have witnessed a growing interest in applications of Wireless Sensor and Actor Networks (WSANs). In WSANs, maintaining interactor connectivity is of vital concern in order to reach application level. Failure of a critical actor may partition the inter-actor network into disjoint segments. This paper proposed an Application-oriented Fault Detection and Recovery algorithm (AFDR), a novel distributed algorithm to reestablish connectivity. AFDR identifies critical actors and designates backups for them. A backup actor detects the critical node failure and initiates a recovery process via moving to the optimal position.
