Abstract

In the heterogeneous network of visible light communication and WiFi, the fairness index of users is a key index when allocating resource bandwidth. In order to improve the fairness of the system, the average request rate of users and the distance from the wireless access point are mainly considered, and a new weight-based multi-team resource allocation algorithm is proposed to judge the priority of users based on these two indexes. First, the request rates of users are ranked in order, and the first and last two users are formed into a queue, and the first allocation is made according to the weight of the queue, and then the second allocation is made according to the respective weights of the users in the queue. The simulation results show that the fairness index is improved and the improved algorithm can be applied to resource allocation in heterogeneous networks.
