Critical Review of Analytical Modelling Approaches for Performability Evaluation of the Handover Phenomena in Mobile Communication Systems

Perform ability modelling and evaluation of wireless and mobile systems have been of interest for recent research work. Especially, because of the complexity of the next generation wireless and mobile systems, modelling and performance evaluation is essential to improve the architecture according to the quality of service. (QoS ) requirements and performance characteristics. A considerable amount of the existing work in literature focuses on handover phenomena using analytical modelling and/or simulation of mobile communication systems. This paper presents a perform ability evaluation framework of mobile communication systems with different handover strategies using analytical modelling approaches. The availability and mobility issues are also considered in the proposed models. Well-known approximate Markov reward model solution and the exact Spectral expansion solution approaches are considered. Perform ability measures of proposed models, such as blocking probability and mean queue length are presented.
