Abstract :
In this paper the PGPS/RAP multiaccess proposed in Chia-Sheng Chang and Kwang-Cheng Chen (1998) is reinvestigated for realistic channel characteristics such as unreliable transmission and propagation delay effect. With our proposed link control scheme, the packet error rate of PGPS/RAP in an unreliable channel can be effectively improved while the packet delay for constant-bit-rate (CBR), variable-bit-rate (VBR) traffic is still guaranteed. Furthermore, with the technique of pipelining, we modify the PGPS/RAP to adapt the long propagation delay effect for guaranteed QoS access to CBR and VER traffic of the end-users. This modified PGPS/RAP without any specific frame concept can still guarantee worst-case jitter of CBR and VER traffic sources and therefore can guarantee the QoS of jitter-sensitive CBR and VER sources
