Dynamic routing network algorithm of low voltage based on link quality

Power distribution network is a dedicated transmission network for power. If you want to use it as communication network, the network traffic will become very complicated. Low voltage distribution network topology is very complex and quite different in different distribution network; and different load leave or input power line will cause a strong performance of channel variability. It is because of these features of low voltage distribution network that it difficult to networking and the network is easily destroyed. This paper presents a dynamic routing algorithm, based on link quality, to improve the reliability of low voltage distribution networks. The algorithm can eventually form an 8-layer structure of the tree topology, and can achieve network self-healing capabilities when the link is broken. The algorithm is suitable for a variety of network physical topology, and finally be able to form a tree structure, thus effectively improving the reliability and system flexibility of communication network. Through the simulation on NS2, we can see the feasibility and network self-healing of the algorithm.
