Inter-Actor Connectivity Restoration Algorithm for Wireless Sensor and Actor Networks: A Survey

Wireless Sensor and Actor Networks (WSANs) refer to a group of sensors and actors linked by wireless medium. In WSANs, sensors gather information and actors take decisions and then perform appropriate actions. Maintaining inter-actor connectivity in wireless sensor and actor networks is very important in mission-critical applications. Failure of one or multiple actors may partition the inter-actor network into disjoint segments. Network operation is hindered by failure of actors. This paper presents a survey on certain algorithms and techniques to restore inter-actor connectivity.
