Content Delivery Networks (CDNs) [79, 97] have received considerable research attention in the recent past. A few studies have investigated CDNs to categorize and analyze them, and to explore the uniqueness, weaknesses, opportunities, and future directions in this field. Peng presents an overview of CDNs [75]. His work describes the critical issues involved(More)
Over the last decades, users have witnessed the growth and maturity of the Internet which has caused enormous growth in network traffic, driven by the rapid acceptance of broadband access, the increases in systems complexity, and the content richness. The over-evolving nature of the Internet brings new challenges in managing and delivering content to users,(More)
In recent years, multimedia cloud computing is becoming a promising technology that can effectively process multimedia services and provide quality of service (QoS) provisioning for multimedia applications from anywhere, at any time and on any device at lower costs. However, there are two major challenges exist in this emerging computing paradigm: one is(More)
Addressing some vital security issues in enterprise grid technologies is particularly important from the software industry’s viewpoint. Enterprise grid computing systems do face unique security challenges, ranging from preventing access control attacks to ensuring encapsulation and safe object reuse to masquerading and brute-force attacks. Hence, the(More)
Body Area Networks (BANs) are emerging as enabling technology for many human-centered application domains such as health-care, sport, fitness, wellness, ergonomics, emergency, safety, security, and sociality. A BAN, which basically consists of wireless wearable sensor nodes usually coordinated by a static or mobile device, is mainly exploited to monitor(More)
Spatially distributed sensor nodes can be used to monitor systems and humans conditions in a wide range of application domains. A network of body sensors in a community of people generates large amounts of contextual data that requires a scalable approach for storage and processing. Cloud computing can provide a powerful, scalable storage and processing(More)
A sensor network is expected to provide effective delivery of its services by taking an appropriate action based on one or more situations that it senses in the environment. However, due to the dynamism of application requirements and user context, it is often required to re-configure services from a sensor network to meet specific application needs. This(More)
Content Delivery Networks (CDNs) [1] have emerged to overcome the inherent limitations of the Internet in terms of user perceived Quality of Service (QoS) when accessing Web content. They offer infrastructure and mechanisms to deliver content and services in a scalable manner, and enhance users' Web experience. However, modern applications do not just(More)
