基于中断策略的节点休眠系统的准时性研究OA

Improving the deterministic and real-time communications capability of data transmission is a major challenge for wireless communications networks.To improve the predictability of data transmission while ensuring the energy consumption of nodes powered by batteries in wireless networks,an interruption strategy is proposed to investigate the punctuality of the system.Un-like traditional just-in-time communications,the number of packets that can be received within the just-in-time reception range is investigated.In this just-in-time communications framework,the data transmission process is modeled as a Markov decision pro-cess,the state transition probabilities and reward functions of the random transmission and interruption strategies are obtained by theoretical analysis,and the theoretical value of the total expected reward is obtained by a matrix iteration algorithm.The results show that the proposed interruption strategy can effectively improve the on-time reception rate of the system compared with the ran-dom transmission scheme of traditional just-in-time communications.
