In this paper, a load-based joint call admission control (LJCAC) scheme for heterogeneous wireless networks is proposed. The LJCAC scheme aims to achieving the load balance in heterogeneous networks as well as guaranteeing the quality of service (QoS) satisfaction. We also develop the analytical models to calculate the connection-level performance of the proposed LJCAC scheme in two typical heterogeneous...
One fundamental issue in supporting multi-cell ultrahigh throughput wireless local area networks (WLAN) is how to coordinate inter-cell interference. In this paper, we present a novel max-min fair resource allocation scheme to increase system capacity and improve the communication quality of cell-edge users. We assume the users within one cell operate on orthogonal frequency channels, while users...
In this paper, we study optimal transmission scheduling and congestion control in multi-hop device-to-device (D2D) communications underlaying cellular networks. The optimization is not only based on the cellular and D2D link qualities but it also takes the interference situation for each possible mode and the quality of service (QoS) requirements of each user into account. The problem is formulated...
