One of the trickiest challenges introduced by cellular communications networks is mobility prediction for Location Based-Services (LBSs). Hence, an accurate and efficient mobility prediction technique is particularly needed for these networks. The mobility prediction technique incurs overheads on the transmission process. These overheads affect properties of the cellular communications network such as delay, denial of services, manual filtering and bandwidth. The main goal of this research is to enhance a mobility prediction scheme in cellular communications networks through three phases. Firs

This thesis is the first academic study of participants on the UK Youth Mobility Scheme (YMS), which replaced the earlier Working Holidaymaker Scheme in 2008. It foregrounds the sociologically informed framework of ‘lifestyle migration’ to understand YMS participants as migrants. In doing so, the thesis contends that binaries between tourism/migration, and tourism/work have oversimplified contemporary practices of youth mobility, and not addressed the ways in which they are increasingly regulated through state immigration regimes. Thus, the thesis begins by examining the policies regulating yo

Specifically, the transmission set selected of user equipments (UEs) are considered for reducing unnecessary handover. A quality-of service (QoS)-constrained problem is then designed to maximize mobility-aware sum rate through the joint strategies of power allocation and transmission set selection. However, the original optimization problem is a non-convex problem, so we need some mathematical transformat

In 2014, Kuo et al. proposed a mobility network authentication scheme and claimed their scheme was efficient and secure. Unfortunately, we find that their scheme has two weaknesses. First, it cannot resist man-in-the-middle attack. Second, it suffers from the synchronization problem in password change phase. In this study, the found weaknesses will be shown in detail, and an improved scheme

However, how to split the IP flows is not clear in the current routing policies, which may lead to the following problems: the IP flows (1) may be routed to a target access network having strong signal strength but with backhaul congestion (or just simply blocked by firewalls), (2) may exceed the capability of the tar
