We first propose a new cell loss scheduling scheme, referred to as the QoS-scheme. This scheme can satisfy different individual quality of service (QoS) requirements of a group of virtual channel connections with minimum required bandwidth. We next derive a simple formula based on Gaussian approximation to allocate bandwidth to heterogeneous VBR video conferencing connections. Comparing the pro...

Dynamic bandwidth allocation for upstream transmission in EPONs has gathered significant attention. Maximizing utilization is inversely related to dynamic bandwidth allocation. We propose an auctioning mechanism for bandwidth allocation with a view to dissolution of the paradox between efficiency (utilization) and dynamism. While conventional bandwidth auctioning schemes pose efficiency as well...

461 Abstract—This paper proposes an efficient bandwidth allocation algorithm in which higher priority is given to the videos with higher weights using agent technology. The popularity and weight profile of the videos which is used for efficiently allocating bandwidth is periodically updated by a mobile agent. The proposed approach allocates more bandwidth for higher weight videos [popular video...

This paper presents a sender side only TCP mechanism to prevent compromise for bandwidth utilization in IEEE 802.11 wireless networks. In absence of mechanism for accurate and immediate loss discrimination, the TCP sender unnecessarily reduces its Loss Window in response to the packet losses due to transmission errors. At the same time, frequent transmission losses and associated link retransmi...
