LTE Simulator Implementation and Performance Analysis of Cellular Network

Ravi R, Subramanya Bhat

Abstract: LTE (Long term evolution) represents an emerging and promising technology for providing broadband Internet access. New Scenarios for LTE can be implemented by analyzing the output performance using LTE Simulator. Unfortunately; at the present; to the best of our knowledge; no open source simulation platforms; to evaluate the performance of the entire LTE system; are freely available. LTE-Simulator; an open source LTE-Simulator has been conceived to simulate uplink and downlink scheduling strategies in multi-cell/multi-users environments taking into account user mobility; radio resource optimization; frequency reuse techniques; Adaptive Modulation Coding (AMC) module; and other aspects very relevant for industrial and scientific communities. The effectiveness of the LTE simulator has been tested and verified considering (i) the software scalability test which analyzes both memory and simulation time requirements (ii) the performance evaluation of a realistic LTE network providing a comparison among well known scheduling strategies such as professional fair (PF) ; Exponential Professional fair (EXP) ; Modified Longest Waited Delay First (MLWDF).
