Distributed Route Resource Allocation Method of the Heterogeneous D2D Communication Network
Due to the complexity and dynamism of Device-To-Device(D2D)communication multiplexing in heterogeneous cellular network environments,it is difficult to achieve efficient and fair utilization of routing resources.Therefore,a distributed routing resource allocation method is proposed for D2D communication multiplexing in heterogeneous cellular networks.Building D2D with distributed system model topological structure of heterogeneous cellular network with communication multiplexing,realize D2D device discovery based on neighbor node information exchange,and introduce an adaptive session establishment strategy to establish communication links.We use greedy algorithms to allocate sub channels for D2D users and achieve balanced allocation of routing resources.The experimental results show that the design method has good performance in improving D2D users and rates,and is suitable for routing resource allocation in D2D communication multiplexing heterogeneous cellular networks.
