A Distributed Approach for Selection of Optimal Actor Nodes in Wireless Sensor and Actor Networks

In this research paper we study the problem of optimal actor nodes selection based on mutual exclusion in the context of wireless sensor and actor network (WSAN) and propose a novel distributed approach to solve it. The major requirements for any proposed approach in such scenario are: (1) the proposed approach should select the minimum number of actor nodes to act on the given incident event region, (2) the overlaps between acting ranges should be minimum to avoid redundant action by actor nodes i.e. wastage of resources should be minimal, and finally, whole event region must be covered by one or more than one actors as per their availability in the network i.e. full coverage should be achieved. We have proposed one novel approach called Distributed Optimal Actor nodes Selection based on Mutual Exclusion approach (DOASME) in this research paper. The simulation results show the performance in terms of size of actor cover set, overlapped region, non-overlapped region and maximum actor coverage degree. We have also compared our simulated results with previously proposed benchmark algorithms.
