Abstract

In this paper, a new traffic source, priority data, is considered to access the channel with the highest priority among conventional CBR, VBR and ABR sources. In order to achieve and maintain QoS guarantee for admitted CBR and VBR sources, a QoS guaranteed wireless access protocol, the priority polling with reservation (PPR) protocol that consists of priority polling scheme (PPS) and randomly addressed polling (RAP) is proposed. We provided the jitter and delay constraints for CBR and VBR sources by reserving bandwidth for the mean PD sources that are active during the time to transmit CBR and VBR sources. The results show that under the preemption of PD sources, the QoS constraints for CBR and VBR sources are guaranteed.
