 BRIEF DESCRIPTION OF THE PROJECT

The WINE project was born to find transparent compensation methods for the poor performance of Internet wireless links in an indoor environment (either home or business) where mobility of users has to be considered. In such an environment, users with mobile Internet-based equipment (e.g., portable computers, mobile devices) require acceptable performance when communicating over the Internet, to perform their everyday work. It is highly desirable to design an Internet-oriented wireless communication system that behaves in the same way as a wire-dominated system to a great extent. Background work in the field proposes adaptive link layer protocols in terms of error control for Internet wireless links. WINE augments existing approaches by introducing the wireless application layer (WAL), which is a generic framework combining adaptive local error control and traffic control.

The project has stuck closely to its goals and the objectives have all been achieved. Experimental and simulation results have given extra clarity to the nature of the objectives. The prototype implementations of the three test platforms (802.11b, Bluetooth, Hiperlan/2) have been presented together with the various optimizing modules of the WAL.

Our group participated actively in the specification of the WINE architecture. It designed and implemented both the FEC and the SNOOP modules for WAL and it developed the demonstrator platform based in 802.11b. It was also one of the main partners dealing with the characterisation of the behaviour of IP protocols over wireless platforms, especially IEEE 802.11.
