A Study on TCP Adaptation Methods for Heterogeneous Wireless Networks
Year: 2010
Type: dissertation
Abstract: Enhancing the quality of communication in the mobile environment is an essential step towards establishing a sophisticated information society.Efforts made to establish high quality communication in the mobile environment have yielded diverse kinds of wireless communication technologies.The rapid progress and deployment of diverse wireless communication technologies provide for mobile nodes the capacity to form heterogeneous wireless networks, in which mobile nodes can employ different kinds of wireless technologies simultaneously to achieve both fast communication and a wide communication range.In the mobile environment, seeking optimized utilization of heterogeneous wireless networks is an effective way to enhance the communication quality.However, the traditional TCP/IP model cannot reap the full benefit of heterogeneous wireless networks since it requires additional solutions to cope with several issues, such as mobility support, fragile data-link characteristics, and different link characteristics of each individual wireless data-link.As an important part of a comprehensive study on the effective utilization of heterogeneous wireless networks, this dissertation studies the issues arising from the different link characteristics of each wireless technology.When a mobile node conducts a vertical handoff, i.e., the mobile node switches from one upstream data-link to another, this usually involves drastic changes in link characteristics.Since the traditional TCP/IP protocols have evolved for stationary networks, the protocols did not envisage such drastic changes and they may not work as expected for heterogeneous wireless networks.In particular, the TCP congestion control mechanism will suffer from such drastic changes and will not work properly.This dissertation presents
