چکیده
To serve traffic with different characteristics and service requirements in multimedia wireless packet networks] we propose a multiaccess methodology PGPS/RAP with guaranteed quality-of-service (40s) to serve constant-bit-rate (CBR), variable-bit-rate (VBR), and available bit rate (ABR) traffic sources. This multiaccess methodology without any specific frame concept can guarantee worst-case delay of CBR and VBR traffic sources and therefore can guarantee the QoS of delay-sensitive, jitter-sensitive CBR and VBR traffic sources. The derived delay bound of a specific traffic only depends on its own traffic parameters. This impressive characteristic benefits bandwidth allocation and consequently results in a simple call admission control policy. Other important issues, including a simple link control mechanism for CBR and VBR over unreliable channels, are also suggested.

A New ARQ Protocol For Wireless ATM Networks - Communications, 1998. ICC 98. Conference Record.1998 IEEE International Conference on
This paper describes the design and performance of a new ARQ protocol for wireless ATM networks. The wireless channel is characterized by a higher and variable error rate in comparison with fiber-based networks for which ATM was designed. The purpose of the protocol is to provide a capability to dynamically support ATM-based communications in a fluctuating transmission environment by using sele...
متن کاملPerformance of space-division multiple-access (SDMA) with scheduling
Efficient exploitation of spatial diversity is fundamentally important to resource critical wireless applications [Tsoulos (1999)]. In this paper, we first study the performance of intelligent scheduling for space-division multiple-access (SDMA) wireless networks [Suard (1998), Farsakh (1998)]. Based on the existing scheme, we propose a new medium access protocol (MAC) for multimedia SDMA/time-...
متن کاملMultirate Scheduling of VBR Video Traffic in ATM Networks
One of the major attractions of Asynchronous Transfer Mode (ATM) networks for transporting bursty video traac is its ability to exploit the multiplexing gains of packet switching while providing quality of service guarantees. Unfortunately, most of the multiplexing mechanisms proposed in the literature fail to exploit the multiplexing gains of ATM. In this paper we propose a multirate service m...
