Wireless broadband technologies are anticipated to flourish in the next few years, due to the increasing demand for wireless connectivity and the need to support enhanced services and applications in local- or wide-area environments. The primary goal in a communication system is Quality of service provisioning to users and hack proof information, which depends on procedures that span several Communication Protocols. A multimedia connection in a wireless network typically utilizes three important network resources: wireless link resource, wired link resource and network server resource. When the users participating in the connection are mobile, these resources must be reallocated as the users move in a manner so that the connection is not disrupted. This thesis seeks to contribute a set of algorithms for supporting connection mobility through efficient and, in certain cases, optimal use of these network resources.
