This paper proposes a model to estimate the packet loss probability in a mesh-based P2P network. Because of the irregular mesh structure, packet loss estimation for a mesh-based P2P network is more complicated than that in a tree-based network. The proposed model takes into account the channel packet drop rate, peer dynamics, and FEC protection to capture(More)
Infectious bursal disease virus (IBDV) causes a highly contagious disease in young chicks and leads to significant economic losses in the poultry industry. The capsid protein VP2 of IBDV plays an important role in virus binding and cell recognition. VP2 forms a subviral particle (SVP) with immunogenicity similar to that of the IBDV capsid. In the present(More)
In recent years, the autonomous mobile robot has found diverse applications such as home/health care system, surveillance system in civil and military applications and exhibition robot. For surveillance tasks such as moving target pursuit or following and patrol in a region using mobile robot, this paper presents a fuzzy Q-learning, as an intelligent(More)
This paper proposes a hybrid sender/receiver-driven error protection scheme to transmit scalable video packets over packet-lossy peer-to-peer networks. In our scheme, given an estimated system uplink capacity, a joint source-channel coding (JSCC) mechanism based on receiver-driven subscriptions is proposed to minimize the visual distortion received by(More)
Due to the rapid improvement in resolution and codec, the number of video sensing device grows fast in the recent years. Tremendous data need to be stored and processed. To meet such a need, we developed a video hosting and processing platform for near-real time applications. An intelligent device can obtain connection-less upload function from our(More)
This paper proposes a distributed packet protection mechanism that can minimize the packet loss probability for mesh based P2P video streaming systems. The proposed scheme combines a peer selection method with forward error correction (FEC) codes. The parent peers select the child peers, which can achieve the minimal packet loss probability compared to(More)
The demands of faster video streaming and higher resolutions induce the next generation video coding standard, High Efficiency Video Coding (HEVC), which utilizes more complicated codec structures to obtain better video compression ratio than H.264/MPEG4. However, its computational complexity also grows significantly. The paper investigates the acceleration(More)
