With growing acceptance of cloud environment, demand for cloud services based applications is rapidly increasing. Cloud environment is inherently distributed and highly dynamic. Usually, many cloud services having similar functionalities but varying performances are offered. This makes difficult for user to identify the appropriate cloud service. Consequently, trust assessment is becoming essen...

The deployment of 3-D image techniques is one of the most promising fields among the development of new applications for natural image scenes. Driven by urgent demands from industry and users, 3-D image technology has received sign...

Many network applications rely on stochastic QoS guarantees. With respect to loss-related performance, the Effective Bandwidth/Capacity theory has proved useful for calculating loss probabilities in queues with complex inputand server-processes and for formulating simple admission control tests to ensure associated QoS guarantees. This success has motivated the application of the theory for del...

Wireless networking has become an important area of research in academic and industry. The main objectives of this paper is to gain in-depth knowledge about the Wi-FiWiMAX technology and how it works and understand the problems about the WiFiWiMAX technology in maintaining and deployment. The challenges in wireless networks include issues like security, seamless handover, location and emergency...

Computer systems have become powerful enough to be capable of processing video and audio data streams in real-time. While processing power and bandwidth are available in abundance, the infrastructure of handling time-sensitive, highbandwidth data is not yet commonplace. This paper shows the approach taken by this research to design a possible implementation of Quality of Service guarantees with...

The BROADEN (Business Resource Optimisation for Aftermarket and Design on Engineering Networks) project aims to build a Rolls-Royce Grid as a proving ground for utilising Grid services technology. One of the central applications in this project is XTO ((eXtract Track Order) which is used to facilitate distributed diagnostics support for aircraft engines. One of the key elements in BROADEN is th...

Communications ecosystem covers a huge area from technical issues to business models and human behaviour. Due to this extreme diversity various societies need to discuss with each other, each of them using their own language. Engineers talk about network performance and quality of service, business people talk about average revenue per user and customer churn while behavioural scientists talk a...

The importance of Feedback Control Theory used for dynamic systems has grown in recent years, due to the fundamental role played in modern technological systems. It represents a well developed analytic foundation for performance control in physical systems. Recent results have shown that the Feedback Control can also be successfully applied to the control of software performances of open system...

Despite a growing body of literature demonstrating a positive relationship between sleep and optimal performance, athletes often have low sleep quality and quantity. Insufficient sleep among athletes may be due to scheduling constraints and the low priority of sleep relative to other training demands, as well as a lack of awareness of the role of sleep in optimizing athletic performance. Domain...

Quality of Service routing for multicast enables a group member to find and install a branch of the multicast tree that can meet its QoS constraints. The most promising protocols in this area use receiver-oriented path searching heuristics to find feasible routes. In this paper, we examine the performance of the path searching heuristics used by these protocols, to determine which techniques ar...
