Hybrid Movement Control Algorithm for Restoring Connectivity in WSAN
Maintaining inter-actor connectivity is very important in WSAN. Failure of one or multiple actors may partition the inter-actor network and obstruct the network operation. This paper presents a combination of two algorithms namely DCR and PCR to tolerate the failure of actors.DCR proactively identifies critical actors and designates appropriate backup nodes. Backup node starts recovery process when failure is detected. PCR determines critical/non-critical actors based on localized information and designates each critical node with an appropriate backup.
