Modeling and simulation of handover priority schemes for broadband wireless networks

Abstract

Modeling and simulation of handover priority scheme for broadband wireless network are under investigation. The aim of simulation is estimation of the probabilities of handover Quality of Service (QoS) parameters as blocking probabilities of handover channels and overflow probabilities of queues. A handover traffic scheme for broadband wireless network handover for heterogeneous traffic is suggested. This scheme is modeled with Markov chain. For suggested queuing model is worked out an algorithm for Markov chain solving. For considered model is suggested algorithms for traffic simulation with imolementation of rare event simulation. As a result is received an estimation of blocking probabilities of handover channels.
