The user requirements in the future wireless networks are heterogeneous. The resource allocation and user association are crucial factors to meet user requirements and save energy. In this paper, the optimization of resource allocation and user association problem in both low data and high data requirement scenario is studied. In the low data requirement scenario, a network energy consumption minimization...
Heterogeneous wireless networks give rise to a multi-radio access environment which becomes crucial for load balancing to avoid network congestion and providing high quality services to maximize radio resource utilization. To this end, a joint power and bandwidth allocation with QoS support algorithm is proposed using convex optimization method in this letter. The algorithm achieves the goal of the...
IEEE 802.16 and Passive Optical Network (PON) are two promising broadband access technologies for high-capacity wireless and wired access networks, respectively. In order to better understand the co-existence of both network technologies and to determine whether closer cooperation in the bandwidth provisioning process is advantageous, an access network that utilizes a Gigabit PON (GPON) to backhaul...
