The Research of IWSN Real - time Reliability Routing Based on Power Regulation

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 consump-tion 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 re-sults show that compared with the existing algorithms,the proposed algorithm has a significant improvement in total reliability,deadline miss rate and packet average delay.
