As content providers adopt peer-to-peer approaches for content sharing and distribution, they face new challenges in guaranteeing privacy to their clients. Participating peers can glean information from their communication with other peers, such as their identities or the shared data and use this information for malicious purposes. We present Nemor, a protocol that allows a requesting peer and a corresponding...
With the development of space science and technologies the exploration of the deep space has become the most important and direct way of exploring the unidentified planets or space resources. The data gathered by the equipment of deep space exploration need to be sent back to the Earth exactly, and the network is in a reliable manner. The transmission protocol of the deep space communication network...
Recent success deployment of P2P streaming can provided hundreds of media channels of users at any given time. This evokes an interesting question can the streaming server allocate channel resources efficiently with limited capabilities? In this paper, we propose an auction-based new strategy for resources allocation. The mechanism enable streaming server can provide service according to peer's bidding...
The use of peer-to-peer (P2P) mechanisms for content delivery is attractive to content and service providers alike. P2P data transfers offload the demand on servers and reduce the bandwidth requirements, with corresponding benefits of improved scalability and performance. This, however, poses interesting challenges in ensuring content integrity. Peers may be malicious and attempt to send corrupt and/or...
GloSDC is a JXTA-based three-tiered framework for global catalog in grid GIS, which is a mechanism of using P2P model to solve the problem of grid replica organization. We use horizontal non-overlapping fragmentation method to partition a logical layer into physical fragments according spatial extent. A fragment layer is an autonomous layer stored in a grid node, being accessed through node SDE. There...
