Modelling and analysis of strategies in the design of WSAN coordination systems

During the past five years, considerable research has been reported on the design of various coordination systems for Wireless Sensor and Actor Networks (WSANs). Though the coordination mechanism taxonomy was presented, there has been no work published for the performance comparison among these different strategies or protocols quantitatively. In this paper, we attempt to address this challenge. The contribution of this paper is as follows: (i) an approach for the performance comparison among different strategies of sensor–actor coordination in WSANs is proposed; (ii) analytical models to abstract the system characteristics and operation for each kind of solutions are developed; (iii) the performance of each individual strategy under various conditions is analysed; (vi) the performance among three typical strategies is compared. The results may be helpful for the users to understand the advantage of each strategy over others under a certain condition.
