Unraveling quality of experience (QoE) of video streaming is very challenging in bandwidth shared wireless networks. It is unclear how QoE metrics such as starvation probability and buffering time interact with dynamics of streaming traffic load. In this paper, we collect view records from one of the largest streaming providers in China over two weeks and perform an in-depth measurement study on flow...

Content centric networks (CCN) is a new content-oriented network paradigm. It changes the communication mode from where to what. CCN can realize efficient content transmission and support consumer mobility inherently because of its receiver-driven characteristic. But it cannot handle provider mobility effectively since the movement will lead to the entire routing information updating. In this paper,...
The tracking robustness can be improved greatly using multi-camera system because the overlapping field of view provides more information of the objects. However, traditional template matching based multi-camera object tracking suffers from the tracking errors brought by view point differences. To solve the problem, we propose the extended online HECOL (Homography and Epipolar-based Consistent Labeling)...
In the emerging peer-to-peer (P2P) live streaming, users cooperate with each other to support efficient delivery of video over networks. Pollution attack is an effective attack against P2P live streaming, where attackers upload useless data to their peers, which may cause distrust among users. To resist pollution attacks and stimulate user cooperation in P2P live streaming, this paper proposes a joint...
In the emerging peer-to-peer (P2P) live streaming, users cooperate with each other to support efficient delivery of video over networks in live streaming applications. Pollution attack is an effective attack against P2P live streaming, where attackers upload bogus multimedia data to their peers. The polluted data can spread over the entire network, and cause severe quality degradation of the videos...
