The purpose of this paper is to reduce the complexity of scheduling scheme for OFDMA/SDMA system with multimedia traffic. To achieve this purpose, we propose a low-complexity beamforming-based scheduling (LCBS) scheme to solve the multi-dimensional (space, time, and frequency) radio resource allocation problem in OFDMA/SDMA systems. By utilizing a semi-orthogonal user selection (SUS) algorithm, the...
The increasing demand for the coverage of high-speed wireless local area networks (WLANs) is driving the installation of a very large number of access points. Wireless mesh networks (WMNs) have emerged as a promising technology in next generation networks to provide economical and scalable broadband access to wireless interconnection of multiple access points which manage individual WLANs in order...
In this paper, we present a new method to analyze the performance of the power saving class type III with a sleep-delay for self-similar traffic in the IEEE 802.16e. According to the operating mechanism of the sleep mode for power saving class type III with sleep-delay, considering the self-similar nature of massive multimedia packet in wireless networks, a discrete-time batch arrival multiple vacation...
Drawbacks such as agglutination between call process and call routing, heavy routing overhead, poor scalability and control complexity, exist in current large-scale multimedia communication. To overcome these disadvantages, we proposed a hybrid hierarchical call routing architecture based on agent. In this layered architecture, instructed by the goal of condensation and flat, and improving transmission...
State-of-the-art vehicles are now being equipped with multiple video channels for video-data transmission from multiple surveillance cameras mounted on the automobile, navigation videos reporting the traffic conditions on the planned route, as well as entertainment-multimedia streaming for passengers watching on rear-seat monitors. Wireless LANs provide a low-cost and flexible infrastructure for these...
In future wireless communications, there will be a mixture of different traffic classes, which have their own load and quality-of-service (QoS) requirements. In this paper, a traffic load and QoS-oriented packet scheduling (TLQS) is proposed for WCDMA communications, which consider the bit error rate (BER), packet loss, delay and traffic load requirements. The BER requirement can be guaranteed by...
