MOST-URGENT-FIRST PROTOCOL FOR REAL-TIME WIRELESS CHANNELS IN A DIGITAL CELLULAR/PCN ENVIRONMENT
A most-urgent-first (MUF) protocol is proposed to solve the problem of accessing reverse (client-to-server) traffic channels, where mobile clients compete to convey their requests to the server. A method is also presented for evaluating the urgency of each client's request for traffic information. The MUF protocol gives more urgent requests higher priority, responds faster to more important inquiries, accommodates more clients in each channel, and allows information sharing among a potentially large number of clients. Moreover, all services can be provided in real-time. Finally, an UltraSAN model has been developed to evaluate the performance of the MUF protocol. Some of the issues related to operation of the MUF protocol are also discussed.
