Integrated approaches to enhance TCP performance over 4G wireless networks

The Fourth Generation (4G) of cellular communication systems is a technology emerging from future wireless networks. In recent years, many researchers and scientists worldwide have been working on government and business funded projects, whose goal is an efficient wireless network, borne from all current technologies. By adapting new solutions for these enhanced telecommunications, superior quality, efficiency, and opportunities will be provided where wireless communications were otherwise unfeasible. Some researchers define 4G as a significant improvement of 3G, where current cellular network´s issues will be solved and data transfer will play a more significant role. For others, 4G unifies cellular and wireless local area networks, and introduces new routing techniques, efficient solutions for sharing dedicated frequency bands, and an increased mobility and bandwidth capacity. One of the main solutions to improve the performance of new wireless communication systems is by improving TCP (Transmission Control Protocol) performance. This article investigates the possible practical solutions to enhancing the performance of TCP over 4G systems.
