TCP/IP Suite Significant Enhancement for 4G Mobile Multimedia Internet Networks

摘要

The 4th Generation (4G) wireless mobile internet networks will be combined through current existing cellular networks (i.e., CDMA2000, WCDMA and TD_SCDMA) and Wi-Fi (i.e., Wireless LAN) networks with fixed internet to support wireless mobile internet as the same quality of service as fixed internet. Each of the networks has own specified protocols, disparity frequency, and maximum data speed and cost characteristics. TCP/IP suite protocols are succeeding in web application of fixed internet, but limited working on the combined networks. Two research directions are available, which are replacement and improvement. Microsoft has issued new protocol suite for replacement. In this paper, we propose a new protocol to improve TCP/IP suite protocols. This new protocol addresses limitation of TCP/IP suite so that it can work on both cellular network and Wi-Fi network simultaneously; sending data requests through cellular network and getting reply from Wi-Fi network. Ns2 Java version (Java Network Simulator) was chosen to simulate the new protocol because of its feasibility. In this paper, we present the results of our simulation.
