The fusion of Multimedia and Internet technology has introduced an ever-increasing demand for large-scale reliable media services. This exposes the scalability limitations of current middleware architectures, as they traditionally operate on either very large-server configurations or on tightly coupled distributed systems. On the other hand, the wide availability of high-speed networks and the ...

In recent years, various applications of Peer-to-Peer (P2P) computing have been widely used because of its unique advantages, which have played an important role in commerce, communications and other fields. The P2P system is essentially a distributed system, without central servers. Each peer is both client and server, who have the same status. However, some features of P2P networks, such as a...

It seems likely that TCG-compliant computing platforms will become widespread over the next few years. Once one accepts that the Trusted Computing paradigm offers an interesting and powerful set of security features, the natural question arises: for what purposes can this technology be exploited? In this chapter, we examine the application of Trusted Computing to securing Peer-to-Peer (P2P) net...

In recent years, we have witnessed the evolution of computing paradigms with the advent of the Internet as a dominant application, content and service delivery platform as well as with the gradual migration of some applications and services from client-server, to edge services, and then to peer-topeer (P2P) and distributed computing systems. P2P computing systems are capable of accommodating a ...

Peer-to-peer computing has emerged as a significant paradigm for providing distributed services, in particular collaboration for content sharing and distributed computing. However, this computing paradigm suffers from several drawbacks that obstruct its wide adoption. Lack of trust between peers is one of the most serious issues, which causes a number of security challenges in the P2P systems. ...

Peer-to-Peer (P2P) computing is a distributed computing paradigm which considers unreliable peer collections as target platform for application execution. In this paper such collections are considered in the context of enterprises. Unlike other P2P scenarios, more control and knowledge is available in regards to peers. This paper focuses on application task scheduling for such environments. Env...

We are interested in peer-to-peer (P2P) computing, where a P2P application consists of a (wireless) network of nodes (peers), and assumes full peer autonomy, no global control, and intermittent connectivity. P2P computing has many advantages over classical client-server and web-based distributed architectures. However, the P2P computing model also has a number of limitations in the mechanisms i...

Content Networks (CNs) are distributed networks/systems tailored to the management, distribution, discovery and delivery of content to Internet users. They can be considered as an extension and improvement of Content Distribution Networks that emerged previously as an innovative technology that can improve the efficiency of static, time-dependent and rich media content delivery atop large-scale...

Grid and P2P systems have become popular options for large-scale distributed computing, but their popularity has led to a number of varying definitions that are often conflicting. Taxonomies developed to aid the decision process are also quite limited in their applicability. While some researchers have argued that the two technologies are converging [1], in this paper, we develop a unified taxo...

Web services are the new paradigm of distributed computing because of their promise toward interoperability of applications and integration of large scale distributed systems. On the other hand, with the ever increasing number of computers all around the globe, peerto-peer(P2P) networks have gained large popularity capitalizing on their open, distributed, inter-operable, cost-effective and reso...
