Adaptive QoS for Mobile Multimedia Services over Wireless Networks
نویسندگان
چکیده
Absfrucf-A wireless network that provides multimedia services should control the quality of the transmission link for users, allocating resources according to the service type of each user, be it voice, video, image or data. This paper proposes a scheme to allocate the desired signal to interference noise ratio (SINR) for those users with multimedia services by exploiting power control and smart antennas, while not affecting users with voice service. A method to quickly initialize new users into such a network is also proposed.

At the core of mobiware lies a novel ad...
متن کاملA Fuzzy Based Approach for Rate Control in Wireless Multimedia Sensor Networks
Wireless Multimedia Sensor Networks (WMSNs) undergo congestion when a link (or a node) becomes overpopulated in terms of incoming packets. In WMSNs this happens especially in upstream nodes where all incoming packets meet and directed to the sink node. Congestion in networks, if not handled properly, might lead to congestion collapse which deteriorates the quality of service (QoS). Therefore, i...

With the emergence of broadband wireless networks and increasing demand of multimedia information on the Internet, wireless multimedia services are foreseen to become widely deployed in the next decade. Real-time video transmission typically has requirements on quality of service (QoS). However, wireless channels are unreliable and the channel bandwidth varies with time, which may cause severe ...
متن کاملNovel Adaptive QoS Provisioning in Heterogeneous Wireless Environment
In this paper we introduce novel concept for adaptive QoS provisioning for multimedia services in wireless/mobile networks. The concept is proven via simulation analysis in integrated environment with 3G and IEEE 802.11 networks. We introduce a new module that provides the best QoS and lower cost for a given service by using one or more wireless technologies at a given time. The performance of ...
متن کاملAn Adaptive Time slot Allocation for Statistical QoS guarantees in Wireless Networks using Cross-layer approach
Quality of Service (QoS) guarantees plays a critically important role in mobile wireless networks. For the real time services like multimedia video conference, the key QoS metric is to ensure a stringent delay-bound rather than high spectral efficiency. In this paper, a cross-layer approach is proposed to investigate the impact of physical-layer infrastructure on data-link layer QoS performance...
متن کاملBandwidth degradation QoS provisioning for adaptive multimedia in wireless/mobile networks
Adaptive multimedia is promising in wireless/mobile networks since it mitigates the ¯uctuation of resources caused by mobility in these networks. However, bandwidth adaptation entails the bandwidth degradation for some applications. In order to effectively characterize the bandwidth degradation and to provide better quality of service (QoS) to users, we propose two new QoS parameters for adapti...
