Abstract

In this paper, we extend our previous dynamic reservation integrated services multiple access (DRISMA) protocol for the integration of constant bit rate (CBR), variable bit rate (VBR) and unspecified bit rate (UBR) traffic over wireless ATM networks. DRISMA provides CBR services by pre-assigning slots in a frame and VBR services by reserving slots on a bandwidth-on-demand basis. By using a request-mini-slot method, it also ensures that UBR traffic only utilizes the residual bandwidth of the CBR and VBR traffic. However, our previous DRISMA protocol provides isochronous services only. In this paper, we propose a novel credit-based scheme for supporting bursty VBR traffic more effectively. This paper describes the operation of the credit-based scheme and presents some simulation results to illustrate its performance
