Network coordinates (NCs) construct a logical space which enables efficient and accurate estimation of network latency. Although many researchers have proposed NC-based strategies to reduce the lookup latency of distributed hash tables (DHTs), these strategies are limited in the improvement of the lookup latency; the nearest node to which a query should be forwarded is not always included in the consideration...
The ever growing request for digital information raises the need for content distribution architectures providing high storage capacity, data availability and good performance. While many simple solutions for scalable distribution of quasi-static content exist, there are still no approaches that can ensure both scalability and consistency for the case of highly dynamic content, such as the data managed...
Kademlia is a famous routing algorithm based on DHT in P2P network research. To conquer the shortages of Kademlia in searching efficiency and the strategy of cache, an improved Kademlia routing algorithm is proposed which can accelerate the hotspots inquiry speed in P2P network and is implemented by using fast table look-up and weights setting method. This technique avoids inefficient inquiry under...
The established host-centric networking paradigm is challenged due to handicaps related with disconnected operation, mobility, and broken locator/identifier semantics. This paper soberly examines another topic of great interest: distributed information object resolution. After recapping the notion of an information object, we review object resolution in today's Internet which is based on uniform resource...
