D2MA: a distributed access protocol for wireless ATM networks

The main purpose of this paper is to assess the feasibility of the distributed control approach in the definition of a wireless ATM MAC protocol. A novel protocol, named D²MA, is presented. D² MA is based on a double distribution of the access procedure and queueing capabilities. All the reservation and scheduling functions are performed by the mobile stations independently, whereas only passive operations are required to the base station. An accurate analytical model of D²MA has been developed. This model examines a single radio cell with a population m of mobile stations acting as traffic sources. Each station is equipped with a finite buffer of B cell size. A comparison with simulation results shows the accuracy of the analytical approach
