摘　　要：针对工业无线传感器网络对延迟、可靠传输以及成本的特殊要求,研究了一种基于功率调节的实时可靠路由协议,将两跳速度策略引入到路由算法中,提高工业无线传感器网络的实时性;将节点剩余能量以及能耗同时考虑,以平衡网络能量并提高网络寿命;引入功率调节机制以绕开路由空洞,提高节点可靠性。仿真结果显示,与已有方法相比,采用的方法在总可靠度、截止期错失率以及包平均延迟上有着显著改善。Aiming at the special requirements of delay,reliable transmission and cost of industrial wireless sensor networks,a real-time reliable routing protocol based on power regulation is proposed.The two-hop speed strategy is introduced to improve the real-time performance of industrial wireless sensor networks.Energy and energy consumption are considered at the same time to balance the network energy and improve the network life;the introduction of power regulation mechanism is used to avoid the routing holes for improving the node reliability.The simulation results show that compared with the existing algorithms,the proposed algorithm has a significant improvement in total reliability,deadline miss rate and packet average delay.
