Prediction based Energy-Efficient Task Allocation for Delay-Constrained Wireless Sensor Networks

Task allocation in wireless sensor network (WSN) is performed to search for an optimal task schedule for WSN to perform an application. In this paper, we consider a task allocation problem for real-time WSN which aims to conserve as much energy as possible while keeping the latency experienced by the network within a specified value. A novel prediction based MinMin heuristic (P-MinMin) search algorithm is proposed. Simulation results show that the proposed algorithm outperforms existing task allocation algorithms in terms of energy consumption and the capability in meeting real-time requirements demanded by WSN applications.
