Abstract

To avoid Network congestion problematic, 3GPP has developed a new cellular standard based packet switching allowing high data rate, 100 Mbps in Downlink and 50 Mbps in Uplink, and having the flexibility to be used in different bandwidths ranging from 1.4 MHz up to 20 MHz, this standard is termed LTE (Long Term Evolution). Beyond the improvement in bit rate, LTE aims to provide a highly efficient, low latency, spectrum flexibility and high capacity to avoid network congestion. The purpose of this paper is to analyze the congestion avoidance capacity for LTE Network. The performance analysis is conducted in terms of system throughput, delay, and Packet Loss Ratio, using different scheduling algorithms implemented at the LTE base station (PF, MLWDF and EXP/PF schedulers).
