Seamless communication is becoming one of the most important issues for the next generation of mobile and wireless networks. In this context, seamless is referred to users that are free to roam around different networks and at the same time stay connected without any disturbance to the ongoing session during the handover process from one network to another. The handover process between these networks spawns long delay or latency, high packet loss, and fewer throughputs which may degrade the performance of real-time applications during the handover process. Therefore, in order to resolve these problems, a new protocol has been proposed by Network-based Localized Mobility Management working group of Internet Engineering Task Force under network-based mobility management protocol. Although this protocol managed to minimize the problems related to network switching, it still suffers several drawbacks during the handover process especially when the movement speed of the mobile user ishigh. This book presents a new integrated solution that aims to reduce the lengthy handover latency, high packet loss, and the performance of video transmission during the high speed mobility.
