Edge-Computing Oriented Robust Routing Scheme in PLC-IoT Networks

The Edge-Computing technology has been widely used in the Power Line Communications (PLC) networks enabled Internet of Things (IoT) for smart power grid. Due to strong noise interference and signal attenuation problem of PLC channel, the throughput of current PLC-IoT networks is limited seriously and fail to support edge computing services. To deal with this problem, this paper proposes an connection oriented robust routing scheme of PLC-IoT networks for the edge computing system. This robust routing scheme can generate end-to-end routes and conduct data transportation for edge-computing services with connection-oriented level. Test results show that the proposed approach can improve reliability routing ability for services brought by IoT for edge computing systems in terms of both packet loss rate and time delay performance with great feasibility and efficiency.
