Estimation of the Available Bandwidth for TCP and UDP traffic over 802.11 WLANs
Wireless bandwidth estimation is a critical issue for quality of service provisioning in IEEE 802.11 WLANs. Current bandwidth estimation solutions focus on either probing techniques or cross-layer techniques and either requires significant bandwidth resources or protocol modifications. To alleviate these problems, this paper proposes an analytical model-based bandwidth estimation algorithm for multimedia services over the IEEE 802.11 networks. The MBE module for available bandwidth estimation is developed based on novel TCP/UDP throughput models for wireless data communications.
