Continuously enriched distributed systems in data centers generate much network traffic in push-style one-to-many group mode, raising new requirements for multicast transport in terms of efficiency and robustness. Existing reliable multicast solutions, which suffer from low robustness and inefficiency in either host-side protocols or multicast routing, are not suitable for data centers. In order to...
Base station (BS) location privacy has been widely studied and researched in different applications like field monitoring, agriculture, industry and military etc. The purpose is to hide the location of BS from outside/inside attacker in any shape. Hundreds of thousands of sensor nodes are deployed in some area, bring lot of new challenges regarding routing, forwarding, scaling and security. Different...
By making the best of the wireless channel's broadcasting property, opportunistic routing can greatly improve the performance of wireless multi-hop networks. Traditional routing security mechanism is no longer suitable for the design of routing protocol in Ad hoc network. So this thesis introduces trust, i.e. the concept of security and credibility into opportunistic routing, and put forward an opportunistic...
Real-time file sharing is important to improve the quality of cloud services. Current cloud systems however fail to efficiently offer cost-effective data analytics due to slow response and energy inefficiency. In order to support real-time processing and improve energy efficiency in the cloud, this paper proposes a novel cost-effective data analytics scheme, called Needle. The idea behind Needle is...
Range query in Peer-to-Peer networks based on Distributed Hash Table (DHT) is still an open problem. The traditional way uses order-preserving hashing functions to create value indexes that are placed and stored on the corresponding peers to support range query. The way, however, suffers from high index maintenance costs. To avoid the issue, a scalable blind search method over DHTs - recursive partition...
