Many call admission control schemes for ATM-type networks are based on the concept of eeective bandwidth (EB). Most such schemes focus on the cell loss rate as the exclusive QoS metric and therefore base their EB on cell-loss rate approximations. We use simulation data to train an adaptive logic network (ALN) to estimate cell loss and delay; these estimates can then be used to compute eeective ...

This paper presents a high precision wide band switched delay line with fine tuning capability and low insertion loss. The circuit is designed to operate in the frequency range from 1 GHz to 5 GHz and tuned using MEMS switches targeting a minimum delay step of 7 ps. The delay line uses a single layer of a high permittivity substrate (εr =10), and the MEMS devices are interconnected using conven...

WLAN has been widely deployed over public and private areas and has become one of popular access technologies for mobile Internet services in recent several years. Handoff between WLAN access points (APs) that introduce packet loss and delay is one of the critical issues for mobile Internet applications, especially for real-time communications. Previous studies indicated that channel scanning t...

The quality of audio in IP telephony is significantly influenced by various factors, including type of encoder, delay, delay variation, rate and distribution of packet loss, and type of error concealment. Hence, the performance of IP telephony systems is highly dependent on understanding the contribution of these factors to audio quality, and their impact on adaptive transport mechanisms such a...

In an ad-hoc network’s there is no specific infrastructure and no static topology. It has more dynamic topology that changes over time and less battery power of the nodes, less bandwidth and transmission quality enhancements. It supported Real time & multimedia application by Manet. QOS have parameter like as easy bandwidth utilization, less delay, minimum packet loss, good throughput, jitter. ...
