III. POSSIBLILTY TO ENHANCING TCP IN 4G
The high rate of data, that is expected for future 4G systems, along with the predicted services provided by this generation, requires strong protocols that are able to overcome the problems and challenges of wireless networks, such as bit error rate, asymmetry between base station and mobile host, and handover possibilities. In addition, these 4G systems (e.g., Long Term Evolution -LTE and LTEAdvanced) support a good concept of Quality of Service (QoS) on radio and transport networks. However, no flow control mechanisms are supported, which may cause some dropping of packets during congestion periods at terminals or nodes [14]
