Research On Routing Optimization For Power Wireless Communication Network

With introduction of the concept of smart grid and its further construction, power communication network plays an increasingly important role in the power production. As the distribution network has the problems of complex network structure and large-scale terminal information acquisition, the use of advanced wireless communications technology to build power wireless communication network becomes the key to smart distribution network. This thesis aims at the network routing problems of the distribution network terminal information collection. The research starts from the distribution network topology feature model, and designs a routing optimization algorithm based on wireless sensor network to achieve an effective distribution network terminal information collection.Firstly, according to problems of the network topology modeling in route optimization study, the thesis starts from analysis of the distribution network structure and distribution communication network topology and presents a weak ring wireless communication network model combined with the wireless sensor network self-organizing network characteristics, which lays a foundation for the design of effective routing optimization algorithm based on the characteristics of the distribution network topology. Aiming at the route optimization problem in small terminal nodes density distribution network applications, the thesis proposes a power control routing optimization algorithm in distribution communications network. The algorithm is based on AODV routing optimization algorithm, refers to wireless sensor network energy consumption model to build the best power control routing model and uses the best route selection mechanism to select the low-power routing to solve the problem of limited energy wireless sensor nodes. OPNET simulation results show that the algorithm can effectively reduce node energy consumption, extend the network life cycle, and improve network throughput. Aiming at the route optimization problem for large terminal nodes density distribution network applications, the thesis proposes a distribution communications network optimized multi-path routing algorithm. The algorithm constructs a node separate multi-path routing, intermediate nodes calculate the performance values according to the network performance function, the source nodes calculate the weights of each path, select primary path and alternate paths from multiple paths for data transmission, and when the primary path fails, the source node is to enable an alternate path. OPNET simulation results show that the algorithm has good communication fault tolerance and reliability.
