With the development of smart grid, the heterogeneous network of PLC, VLC and RF needs to meet the transmission with high-speed, energy efficiency and reliable access for a large number of indoor data, such as intelligent dispatching, power distribution data and indoor Internet of Things information. And it becomes an effective access way to achieve seamless coverage for indoor applications. Aiming at the difficulties of channel characteristic evaluation, handover decision complexity and energy efficiency resources allocation when information wants to be transmitted efficiently in PLC-VLC-RF heterogeneous network, this project intends to study: .(1).Firstly, we establish the channel model of fusion transmission for PLC, VLC and RF network, study the estimation method of key parameters of fusion channel based on stochastic statistical method and the distribution characteristics of parameters, and design the fusion method. The reference model of fusion channel is optimized by combing the parameter fitting and interpolation methods. .(2).Secondly, we study the network access evaluation index and handover criteria of equivalent SNR of PLC, VLC and RF are designed, and the energy-efficient PLC-VLC-RF handover mechanism to meet the switching QoE performance of different services. .(3).Thirdly, based on game theory, we research the bidirectional relationship between user’s QoE and network performance, and the optimal matching method for energy efficiency allocation of heterogeneous resources. Based on virtualization method of heterogeneous network resources, we design a virtual network mapping method to balance the load-energy. Based on small world model, we study a resource allocation method is designed to improve node clustering and maximize the SW (Small World) eigenvalue when mapping virtual links. . In conclusion, above research results are helpful to improve the resource-energy efficiency in indoor short-distance information transmission and to improve resources utilization of the heterogeneous network.
