The task allocation strategy based on plexity and dynamic scheduling algorithm based on the task scheduling strategy are designed. Firstly,thetask is posed to a number of sub鄄tasks,Multi鄄band Turing machine is applied to the input of the task. The directedacyclic graph is formed though the calculation of the appropriate selected nodes. Second,task scheduling sequence tablesare formed and tasks are processed in sequence through scheduling priority. The experimental results show that thisstrategy reduces munication time and waiting time of running tasks in WSN. Meanwhile,the ess rate of thetask scheduler is improved and the efficiency of the system is optimized words:WSN;task scheduling;
