Hybrid connectivity restoration approach for WSANs
Harinder Pal Kaur · 2016
Wireless Sensor and Actor Networks (WSAN) have been very popular from the research community because of their suitability for real time systems. To maintain inter-actor connectivity is crucial in real time situations where actors have to quickly take corrective actions to detected events. Failure of actor and sensors partitions the inter-actor network into disjoint segments, and thus disrupt the network connectivity. Various approaches have been proposed to restore the connectivity of the network. This paper proposes the node failure recovery scheme known as hybrid connectivity restoration approach that works in a distributed manner for detecting partitions in a network and restore the connectivity. This approach may involve relocation of multiple sensors and actor nodes on the path and also analyze the energy consumption of each node before selecting them as a backup node. Thus, reducing the message overhead, less data backup energy consumption, and improves network connectivity. The effectiveness of this hybridization is validated through various simulation experiments.
