Quality evaluation of MPEG4 video transmission over GPRS networks.. Presented by: Abdullah M. Rana Multimedia Communication

Project Overview… Motivation of the Project… ◦ Multimedia Transmission ◦ Low bandwidth wireless networks ◦ Cellular Network infrastructure ◦ GPRS as the medium ◦ Applications requiring better audio/video quality these wireless networks.. ◦ NS2 Network Simulator ◦ Evalvid- Quality Evaluation.

GPRS GSM based architecture Provision for multi slotting IP Network Channel Protection Coding schemes (CS1-CS3) Packet switched radio transmission Suited for bursty applications (e.g. Internet) Data rates up to 170 kbps Re-uses GSM resources Lower call set-up times; cheaper Scheme Code Rate Throughput(bits/ts) Data Rate cs-I I / cs-2 2/ cs-3 3/ cs

GPRS architecture

Network Simulator NS2 Event driven simulator Split language – OTcl and C++ Nodes and links; routing algorithms; queuing schemes Protocols – TCP, UDP, IP Traffic generators – CBR, Exponential, Pareto Basic mobility support. Graphical interface NAM Graphs - Xgraph
