Abstract

In wireless sensor networks, it is an important problem to adjust the work time window in each working/sleeping period to save energy under light network loads and decrease the packet delay under heavy network loads. In this paper, we introduce reinforcement learning method into this problem. We discuss the algorithm design method in a simple IEEE 802.15.4 network, where an RL-based adaptive algorithm is proposed. Simulation results show that this RL-based algorithm can adapt to the change of data flow and make a good tradeoff between the energy-saving performance and the packet delay performance.
