The dynamic packet reservation multiple access scheme
Zygmunt J. Haas, D.A. Dyson · 2003
The performance of the dynamic packet reservation multiple access (DPRMA) protocol for medium access control (MAC) is investigated in this work. This MAC protocol is designed for use in a wireless ATM system. A primary feature of DPRMA is the centralized controller, a base station in a cellular system, whose responsibility is to allocate resources on the uplink channel. The base station does this in an intelligent fashion based on the resource demands submitted by each active mobile and the Quality of Service (QoS) requirements of each type of user. Each user is responsible for providing updated information about its immediate bandwidth needs. The ability of the mobile to dynamically change its bandwidth reservation request is another primary feature of the system. The system investigated in this work contains voice, video conferencing, and data traffic.
