摘要: Recent years have witnessed a growing interest in applications of wireless sensor and actor networks (WSANs). In WSANs, maintaining interactor connectivity is vital concern order to reach application level. Failure critical may partition the inter-actor network into disjoint segments. This paper proposed an application-oriented fault detection recovery algorithm (AFDR), novel distributed reestablish connectivity. AFDR identifies actors designates backups for them. A backup detects node failure initiates process via moving optimal position. The purpose satisfy requirements, reduce overhead, limit impact on coverage utmost. effectiveness validated through simulation experiments.
