Multimedia applications have been the key driving force in converging fixed, mobile and IP networks. A major hurdle in the realisation of this convergence is obtaining Quality of Service from a heterogeneous, best-effort service network. Interactive voice requires strict bounds on delay, jitter and packet losses, video adds significant bandwidth requirements to the network, while Internet only makes...
Wireless networks and multimedia applications are two rapidly emerging technological trends. The IEEE 802.11e protocol has been developed to support QoS for such delay-sensitive applications in wireless networks. This protocol has also been extensively studied in the literature over the past few years, and several mechanisms to improve its performance have been proposed concentrating on ways to reinforce...
Recent rapid developments of high-speed wireless access technologies enable us to use real-time multimedia services as well as legacy non-real-time services via wireless access systems. These multimedia services require QoS (Quality of Service), such as low PLR (Packet Loss Rate) and short delay time. To provide QoS guarantee in wireless LAN (Local Area Network) environment, this paper proposes a...
Nowadays, it is very important to study the behavior of the wireless networks due to the variety of applications that make use of this technology. These applications frequently require a minimum QoS in order to work properly and guarantee a good service to the user. This paper aims to find a relationship between signal to noise ratio (SNR) and a 802.11g networkpsilas QoS in terms of latency, packet...
