Mobility load balancing (MLB) redistributes the traffic load across the networks to improve the spectrum utilisation. This paper proposes a self-organising cluster-based cooperative load balancing scheme to overcome the problems faced by MLB. The proposed scheme is composed of a cell clustering stage and a cooperative traffic shifting stage. In the cell clustering stage, a user-vote model is pr...

The explosive growth of mobile data traffic and the shortage of the available spectral resources have created new challenges for future cellular networks. In particular, resource management in heterogeneous network environment has become a critical issue. In this paper, we propose software-defined networking (SDN)-based resource management algorithms for future cellular network. Specifically, i...

With the rapid increase in demand for mobile data, mobile network operators are trying to expand wireless network capacity by deploying wireless local area network (LAN) hotspots on to which they can offload their mobile traffic. However, these network-centric methods usually do not fulfill the interests of mobile users (MUs). Taking into consideration many issues such as different applications...

Offloading onto Device-to-Device (D2D) communications has been considered as a promising technology to alleviate the traffic load of cellular networks. However, the success of D2D communications actually relies on the willingness for users to share contents and operator’s incentives to tolerate interference in networks, which has been overlooked in most literature. We therefore propose an incen...

An enormous amount of cellular data traffic has been produced by mobile users which exceeds the capacity of cellular network and hence weaken the network quality. The solution is to enhance the capacity of cellular networks which however is expensive and inefficient. As DTNs and Wi-Fi hotspots usually focus on maximizing the amount of cellular traffic that can be offloaded. In most cases due to...

The mobile traffic has grown rapidly with the popularity of smart mobile devices. To accommodate increasing traffic, heterogeneous network integration is considered as a viable solution. By overlapping the coverage of heterogeneous networks (e.g., the long-term evolution (LTE) and Wi-Fi integrated network), the mobile operators can use the offloading service (e.g., Wi-Fi offloading) to reduce n...
