Drive-thru Internet has become a popular solution vehicular Internet access. However, the quality-of-service provisioning for high-data-rate drive-thru Internet services poses significant challenges upon medium access control (MAC) in a large-scale and highly dynamic vehicular environment. In this paper, to achieve high throughput in drive-thru Internet, we exploit the mobility interdependency between...
Nowadays, millions of Internet users watch and upload a large number of videos on User Generated Content (UGC) sites (e.g., Youtube) everyday. Moreover, online videos about hot events, such as breaking news and Olympic games, attract lots of users. In this paper, we study the characteristics of hot-event videos by collecting video traces of the largest UGC site in China for 28 days. We first empirically...
Monitoring the status of running applications is a real life requirement and important research area. In particular log analysis is often required to understand how the system is behaving during execution. For example it is common for system administrators to collect and view logs from different hardware and software components to gain an understanding into system behavior, especially during activities...
The current implementation of BGP protocol has a variety of vulnerabilities and weakness. Monitoring BGPpsilas behavior is an effective way to improve the security of inter-domain routing. Due to the difficulty of obtaining routing tables from autonomous systems, a packet-based model for detecting routing anomalies is presented. This model contains data collectors, anomaly detection engine, routing...
