Traffic Modeling of LTE Network under User Group of Dissimilar Bandwidth

Abstract

In LTE (Long Term Evolution) a user has the provision of use of dissimilar bandwidth. Hence the traffic model of such network is different compared to previous generations. In this project work, we have provided a new modified Markov chain which matches the traffic model of LTE. The Markov chain is solved using node equations where all the linear equations are represented in generalized form so that the chain of any length can be solved using the model of the project work. The standard software MATLAB has been used for our numerical calculations. Finally, the probability states, blocking probability of narrow and wideband traffic are plotted against both call arrival rate and call termination rate. The modified Markov chain provides diverse results in context of bandwidth, compared to that of previous work of 2G/3G mobile
