The use of peer-to-peer (P2P) networks for multimedia distribution has spread out globally in recent years. The mass popularity is primarily driven by efficient distribution of content, also giving rise to piracy. An end user (buyer) of a P2P content distribution system does not want to reveal his/her identity during a transaction with a content owner (merchant), whereas the merchant does not w...

Due to the content bundling and the dramatic increase of content size, the download performance in peer-to-peer networks has become a research focus again recently. In this paper, we propose a novel approach to improve the download performance based on the classical space-time trade-off. With the approach, a peer can speed up local downloads in peer-to-peer networks by contributing a portion of...

Peer-to-peer (P2P) services allow users to share networked resources, notably bandwidth and content, from the edges of the network. These services have been popularized because of file sharing — particularly the sharing of unlicensed copyrighted files. Concerns about such P2P file sharing were highlighted by content owners’ recent lawsuits against individual users and P2P network operators. How...

This paper proposes an efficient algorithm for clustering nodes, classifying and replication of content on demand basis for content distribution in p2p overlay networks. Peer-to-peer overlay networks are a good solution for distributed computing than client-server model since nodes in P2P networks act both as client and server. With such functionality of managing replicas is an astonishing task...

With the explosive growth of vehicle applications, vehicular networks based on millimeter wave (mmWave) bands have attracted interests from both academia and industry. mmWave communications are able to utilize huge available bandwidth provide multiple Gbps transmission rates among vehicles. In this paper, we address content distribution scheduling problem in networks. It has been challenging fo...

Water distribution networks are one of the important and costly infrastructures of cities and many meta-heuristic algorithms in standard or hybrid forms were used for optimizing water distribution networks. These algorithms require a large amount of computational cost. Therefore, the converging speed of algorithms toward the optimization goal is as important as the goal itself. In this paper, a...

Content Distribution Networks (CDNs) have been developed and evolved to meet the growing commercial need for efficient and secure delivery of content over the Internet. Several proprietary CDN systems are now operating successfully, fulfilling the commercial demands to a certain extent. The protocols and algorithms used in these systems are mostly of proprietary nature and not standardized. Fur...
