Scheduling Solution Decrease The Total Task Completion Time in Wireless Sensor Actor Network

In this paper, we present a scheduling model based on queuing theory to minimize the network make-span in wireless sensor and actor networks. We compute the best rate of distribution of tasks by the network sink to allocated actors through a steady state analysis of our proposed model to solve equations and inequalities. It is shown that this distribution rate can enhance the total residual energies of the actor nodes, too. Experimental results on a typical scenario have shown approximately 40% improvement in reducing the make-span and 20% enlargement in reserving energies of the actors compared to the stochastic allocation of tasks to the actors
