Internet-based video streaming applications is becoming more and more popular and attract millions of online viewers every day. The incredible growth of viewers, dynamics of participants, and high video quality-of-service (QoS) requirement pose scalability, availability and low-latency challenges to peer-to-peer (P2P) live video streaming systems. Tree-based systems have low-delay but are vulnerable...
Data sharing is one of the most popular applications that dominate 70% of data traffic on the Internet. This application has been penetrating wireless mobile networks with dramatic speed, which allows the sharing of data whenever and wherever. However, traditional client-server data sharing model suffers from single point failure and low-scalable transmission in a highly dense and dynamic scenario...
Mobile ad hoc networking works properly only if mobile nodes cooperate in routing. However, since wireless mobile nodes are usually constrained by limited power and computation resources, some selfish nodes may refuse to forward packets which are not of their direct interest. Most previous efforts counter this behavior by having each node keep a reputation table and exchanging the information with...
Internet-based distributed systems enable globally scattered resources to be collectively pooled and used in a cooperative manner to achieve unprecedented petascale super computing capabilities. Numerous resource discovery approaches have been proposed to help achieve this goal. To report or discover a multi-attribute resource, most approaches use multiple messages with each message for an attribute,...
