Application Of MOSEL-2 Language In Performance And Modeling Of Cellular Wireless Networks

Today's cellular wireless networks must meet increasing challenges of handling a larger demand for service without a loss of quality, by maximizing the spectral efficiency of the network. Therefore, performance evaluation and modeling of cellular wireless networks is considered to be an important issue to overcome the problem of limited resources of the network. MOSEL-2 (MOdelling Specification and Evaluation Language) offers the ability to evaluate complex systems in a straight, simple and very friendly environment. The old version of MOSEL offers only performance evaluation of complex systems with exponential distribution. However, by the new version of MOSEL (i.e. MOSEL2) with new constructs, it is possible to handle other behaviors with non-exponential distribution. In this paper, the application of MOSEL-2 in cellular wireless networks with mix service is presented. The main objective of the call admission control algorithm and the analysis is to obtain lower handover blocking probability over the new call blocking probability for both voice and data connections, which leads to minimum grade-of-service (i.e. < 0.01) over the whole cell. The numerical analysis of the suggested model with the associated interesting performance measures proves the effectiveness of this simulation in describing and solving this type of systems.
