Abstract :
In the Long Term Evolution (LTE) network, buffer overflows often occur in the evolved Node B (eNB) when dealing with the traffic bursts from the wired part due to restricted bandwidth or environmental interferences in the wireless part. In this paper, a novel approach is proposed to protect the buffer from overflow by appropriately controlling the advertisement window to enhance the Transmission Control Protocol (TCP) when the buffer becomes congested. The sender will slow down the data sending rate upon the receipt of reduced advertisement window, and hence the buffer overflow will be alleviated. To evaluate the suggested solution, a LTE network model is implemented and validated through extensive numerical experiments. It is demonstrated that the proposed approach can enhance the end to end system performance in terms of network throughput, average packet delay and jitter, as well as packet loss rate.
