Integrating GSM and Internet for Mobile Computing

Abstract

Recent advances in wireless communication technology have made a world-wide cellular telephone network practical. On the other hand, the current TCP/IP Internet has a richer data computing resource and is an extensively used data network. In the near future, a mobile user can be expected to carry a portable computer with a wireless interface to access information from anywhere and at any time. Such a communication environment is called a Mobile Computing System. In this paper, we propose an infrastructure capable of integrating Internet with the existing GSM system to provide wide-area mobility for mobile computing applications. An efficient routing mechanism is also developed for the proposed infrastructure. The routing mechanism is not only compatible with the current TCP/IP protocol, but can also interwork effectively with the existing mobile IP proposals.
