Abstract :
This paper presents a method of priority-based lowpower task scheduling in wireless sensor network. The nonlinearity and recovery effect of the battery is exploited. We define a super-period and frame of the tasks, and explain the proposed algorithm. Our experiment results show that this algorithm reduces the consumed energy of all tasks effectively, and extends the node´s lifetime.
