The General Packet Radio Service (GPRS) is designed for packet switching data transmission and provides mobile access to packet data networks, e.g. the Internet.
In this paper, two different protocols are proposed to study the performance of multimedia integrated traffic (as voice, rt-VBR video and data traffics) over GPRS
network. Data traffic is presented as Web documents. This work is based on PRMA (Packet Reservation Multiple Access) access techniques. The simulation objectives include maximizing the system capacity "by finding the optimum permission probabilities of sending contending voice and data, the number of video reserved slots, also measuring Qos through two parameters, the packet dropping probability and the
average delay suffered by each packet ". The obtained Results show that, the performance of GPRS measured in terms of system throughput, video and voice
dropping probability and the average data delay are more enthusiastic compared with the previous studies. So mobile users can access to Internet and obtain data in short time. |
