Biological scientists work with bioinformatics algorithms that are either computational or data intensive in nature. Distributed platforms such as Grids and Peer-to-Peer (P2P) networks can be used for such algorithms. Classical Grid Computing platforms are available only to a restricted group of biologist, since they are expensive, and require skilled professionals for deployment and maintenanc...

One of the most intriguing trends in the development of internet applications in past few years is the immense rise in popularity of peer-to-peer (P2P) applications and networks. Peer-to-peer networks are characterized by the lack of central control or a-priori hierarchical organization in which all or most communication is symmetric. Moreover a P2P system is expected to scale gracefully as the...

Clusters, grids, and peer-to-peer (P2P) networks have emerged as popular paradigms for next generation parallel and distributed computing. They enable aggregation of distributed resources for solving large-scale problems in science, engineering, and commerce. In grid and P2P computing environments, the resources are usually geographically distributed in multiple administrative domains, managed ...

Peer-to-peer networks have gained a lot of attention over the last couple of years, mainly due to the popularity of the free multimedia file-sharing program Napster and a legal battle around it. Being open by nature P2P systems represent an ideal environment for various types of malicious intrusions. The problem of securing hosts on P2P network while keeping the openness of the system has been ...

Efficient communications among computers participating in Peer-to-Peer (P2P) computing remains a problem when they are geographically distributed across multiple network domains. In this paper, we propose DINCast to support group communications required in P2P computing. DINCast is built on top of an existing P2P multicast tree and results in a hop efficient dynamic multicast infrastructure. We...

With the increasingly developed technology of mobile devices and wireless networks, more and more users share resources by mobile devices via wireless networks. Compared to traditional C/S architecture, P2P network is more appropriate for mobile computing environment. However, all existing P2P protocols have not well considered the characteristics and constraints of mobile devices and wireless ...

Peer-to-Peer is a model of communication where every node in the network acts alike. It is as opposed to the Client-Server model, where one node provides services and other nodes use the services. Peer-to-peer computing takes advantage of existing desktop computing power and networking connectivity, allowing economical clients to leverage their collective power to benefit the entire enterprise....

Cloud computing is a promising profitable infrastructure framework that assures to eradicate the requirement for sustaining expensive computing facilities by companies and institutes alike. Information systems supported on the cloud computing and peer-to-peer (P2P) model are now receiving popularity. In the cloud computing form, a cloud of servers sustain few clients with different types of ser...

Recently P2P networks become more and more popular. Though they have many advantages, P2P networks suffer from authentication of nodes. To overcome this problem, a new authentication method called Hash-based Distributed Authentication Method (HDAM) is proposed. HDAM realizes a decentralized efficient mutual authentication mechanism for each pair of nodes in the P2P network. It performs a distri...
