Service disciplines performance for best-effort policies in packet-switching wireless cellular networks
Wessam Ajib, Philippe Godlewski · 2002
In this paper, we investigate the performance of service disciplines for packet-switched wireless networks in the context of General Packet Radio Service (GPRS). The GPRS is a new additional GSM service, which provide packet switched data services over GSM networks and a packet access to data networks. Using either best effort service or guaranteed performance service, the service discipline affects considerably the MAC layer performance. To provide best possible performance for best-effort traffic in packet switching wireless networks, several service disciplines are proposed. We describe their mechanisms, and differences. The performance of these policies is studied in terms of throughput, delay and loss rate by simulating various traffic applications in GPRS context.
