Modeling and evaluation of channel management for real-time multimedia connections in highway cellular networks

The wide deployment of multimedia services in third generation wireless networks will require designs that can simultaneously reduce the blocking probability of handoff requests and decrease the handoff delay. In this paper, we discuss this type of designs for dynamic channel assignment and reassignment strategies in highway cellular networks with a small channel reuse distance. A threshold-based approach to reduce the number of messages exchanged among base stations is presented. The properties of the two real-time schemes covered in this paper are presented and the global balance equations for the first scheme is derived based on the cell decoupling approximation model
