Dynamic Reliability Based Multicast Routing Scheme of Power Line Communication Networks

The power line communication (PLC) technology has been widely used in the Internet of Things (IoT) for smart power grid. Due to strong noise interference and signal attenuation with the time-varying problem, PLC networks suffer greatly from reliability issue and fail to support multicast services. To deal with this problem, this paper proposes a multicast routing scheme based on dynamic reliability for PLC networks in IoT system. This scheme can select nodes and links with high reliability to form the main-tree of multicast. Moreover, it allows leave nodes to be emerged into main-tree through path with better robust. Test results show that the proposed approach can improve multicast services brought by IoT systems in terms of both packet loss rate and robust performance with great feasibility and efficiency.
