An energy-efficient method for real-time processing tasks for wireless sensor networks

To meet the needs of wireless sensor networks for cooperative task processing, a complicated task solution scheme based cooperation (CTSC) is proposed in this paper. The CTSC firstly divides task modules into different groups based on the task graph to reduce the response time of task processing and minimize the communication energy consumption effectively. And then, the collaboration nodes are chosen by means of bid invitation based on a grade field model of sensor nodes. The grade field mechanism can ensure the optimal allocation of tasks to realize the balance of energy consumption and achieve the performance optimization. The comparison results obtained by a simulation experiment show that the CTSC is more suitable for large scale of wireless sensor networks, and it can effectively reduce the response time of task processing with less energy consumption.
