Recently, there has been a rapid growth of efforts in research and development to provide mobile users the means of “seamless” communications through wireless media. Wireless service providers are currently offering new data services such as image transfer, video conferencing, data transfer, and access to an increasing number of content providers. These new wireless data services are noticeably suffering from poor quality compared to its wired versions. This can be attributed to the fact that the infrastructure is inherently uncertain and resource limited. The uncertainty about user mobility is one of the root cause behind an evident waste of wireless resources, which are already limited, due to unnecessary resource reservations. To support highly mobile users with dynamic bandwidth requirements, it is essential for future wireless networks to have efficient mobility management schemes. This suggests that predictive mobility management will undoubtedly play an increasing role in wireless data networks since it can provide information crucial for efficient resource utilization. Location update messages need to be sent whenever the mobile user moves from one cell to a new cell. The overhead of such location update is huge for networks with small cells and large number of mobile users. This presentation discusses the design of prediction schemes for handoff management and connection rerouting for wireless Internet hosts so that disruption to data traffic is minimized in order to maintain a certain level of Quality of Service.
