With the development of information technology, the demand for video transmission in
wireless networks rapidly increases. The traditional traffic shaping algorithms cannot fully (or …

The modern communication system has made the world a “Global Village” in true sense.
However, as the number of users of this communication system is increasing, the challenges …

Due to the harsh Quality of Service (QoS) requirements of video streaming, it is a great
challenge to provide multimedia service over wireless networks. In this paper, we consider …

A stream-based mapping mechanism (SBM) is proposed for improving the quality of MPEG-
4 video delivery. The proposed design keeps two factors in our previous works: significance …

The multimedia streams over the wireless access networks has increased dramatically over
the past few years. Since the wireless link is featured with restricted bandwidth and limited …

The performance of IEEE 802.11 wireless local area networks in combination with a
hierarchical token bucket traffic shaper is assessed. The analysis allows the basic …

Providing real time Quality of Service over Wireless Local Area Networks is becoming a very
challenging task in heavy loaded traffic scenario. Currently high throughput wireless …

To adjust the traffic burst rate and support dynamic service flows, a multi-service token
bucket algorithm was proposed to quality of service architecture in cable modem of HFC …

For the video packets delivery over 802.11 e WLAN networks, an improved cross-layer
mapping (ICLM) scheme is presented in this paper. There are four access categories (ACs) …

In IEEE 802.11 wireless LAN (WLAN), due to the combination of a first-in-first-out (FIFO)
transmission queue and the retransmission policy in the serving access point (AP), a single …
