Abstract
In smart grid systems, heterogeneous networks are considered as a promising solution to address the expeditious growth of mobile traffic. Considering the different user preferences, how to efficiently utilize the limited resource of small base stations (SBSs) becomes a challenge. In this paper, we investigate a joint handover and transmission strategy for users. We formulate the handover and transmission problem to minimize the service delay, which considers the overlapped coverage of SBSs and the limited capacity of backhaul link. To solve this NP-hard problem, we design a heuristic algorithm with two phases. In content caching phase, the contents are cached at SBSs according to the greedy algorithm. In content delivery phase, a transmission strategy is designed to meet the user demands for videos with different quality level. Simulation results show that our proposed algorithm has the advantage of reducing video delivery delay and saving the backhaul traffic compared with other algorithms.
