QoS Routing Algorithm of WSN for Smart Distribution Grid

Recently, Wireless Sensor Network has drawn wide attention on collecting and communicating data for Smart Distribution Grid (SDG). In order to establish a routing system satisfying the latency and reliability requirements of smart distribution grid, a novel routing algorithm with layered cooperative processing and QoS Guarantee Control function is presented in this study. By researching link reliability and path delay estimation method, optimized latency and link quality routing decision method, and on-demand and priority-based buffer queue execution method, the end-to-end data transmission performance of WSN for SDG communication are optimized. The simulation results indicate that our routing protocol can provide QoS for SDG according to their requirements.
