Congestion control for best-effort services in wireless access network
Seungcheon Kim, Abbas Jamalipour · 2002
3G and beyond wireless networks will support user mobility fully based on mobile IP and provide multimedia services like video-conferencing etc. Although the outstanding service will be the real time service, the best effort service class will still remain as a basic service for Web browsing and short message services. Current Internet mostly relies on the TCP sliding window and slow start to regulate the source data rate and prevent congestion in the network. This paper describes network level congestion control based on explicit congestion notification (ECN) and introduces the future wireless network architecture. Also, wireless network traffic problems are introduced with numerical results and computer simulations, which shows the throughput improvement and increase of network stability when the proposed method is adapted in future wireless networks.
