A combined polling and random access protocol for integrated voice and data wireless networks

A combined polling and random access protocol (PRAP) with centralized control for integrated voice and data wireless networks is introduced in this paper. PRAP uses a centralized polling strategy to control network traffic and a distributed random access mechanism to enhance the services to mobile users. Since different data types have different characteristics of the channel usage, PRAP also gives the base station the control ability to fit those characteristics and improves the channel utilization dynamically.
