Abstract: Various local communication techniques are employed in the power system.The coexist of multiple protocols in power networks leads to various communication rates,resulting in difficulty of heterogeneous fusion.Aiming at this problem,a cross-layer communication rate matching mechanism between heterogeneous links is proposed.In the link layer,the link utilization rate is improved by means of the rate requirement based access control mechanism.Using the dynamic store-and-forward method,the communication rate is matched and forwarded among different network interfaces.Furthermore,in the network layer,data rate matching based on multipath transmission is proposed to achieve the maximum data rate matching and improve the communication efficiency.Simulation results have demonstrated the validity of the proposed rate matching mechanism based on cross layer design.In addition,compared with the RBAR protocol and ARF protocol,the proposed mechanism can be used to improve the network throughput,while reduce the delay and packet loss rate.
