Abstract
Long Term Evolution (LTE) is a 4Generation developed by 3 generations Partnership Project (3GPP), all-IP wireless protocol that evolved from Global System for Mobile Communications (GSM). Transmission Control Protocol (TCP) is determining the performance of the protocol in IP Network. TCP variants have been proposed in LTE network. It can be used to improve quality of service (QOS) parameters such as throughput, average delay. In this paper, an enhanced approach is proposed to improve performance TCP of LTE network. The proposed approach depends on controlling the receive buffer size in eNode B. This will he performed through dividing the memory size of eNode B between active users and adapt congestion window size at the TCP users dynamically. Simulation results demonstrate the effective of the proposed approach to enhance the system performance in terms of network throughput, low delay and packet loses.
