According to the localization principle of the Dv-hop algorithm, this paper proposes two improvements including the estimation of average single hop distance, the calculation of distance between unknown nodes and reference nodes. The localization performances are analyzed in theory and with simulations at different communication radius and the rate of anchor nodes. The results show that the proposed improvements can greatly enhance the localization accuracy of the unknown nodes. In addition, the proposed schemes do not change the localization process of the Dv-hop algorithm, and hence they need no further communication resource. It is an optional scheme of localization.

This paper proposes a blind watermarking algorithm based on B-rep for CAD models, the algorithm embeds watermarking aiming at NURBS surfaces or curves, and its merit is preserving the model’s shape exactly. Firstly, we go through the model for obtaining all NURBS primitives, and order these primitives by its length, then use interfacing knot insertion method to embed generated watermarking into ordered primitives. Semi-Blind watermarking is improved and becomes All-Blind watermarking, so we can directly extract watermarking from corresponding ordered NURBS curves, and don’t need provide origin model and origin watermarking messages. At last, through comparing the similarity both the extracted watermarking and origin messages to test if this watermarking is distorted or not. Results show blind algorithm can embed high-capacity watermarking into models, and reduce the time of extracting watermarking.

Abstract:One advantage of the network coding based P2P live streaming system is that multiple source peers can serve the requests efficiently without explicit cooperation control. However, the lack of cooperation also brings redundant data due to the linear dependence, even when the Galois field of the coding coefficients is large enough. In this paper, we first analyze the causes of the redundant data. Then, we propose selecting active source peers from the source set given by the tracker to handle this problem. Active source peer selection problem can be regarded as a variant of 0-1 knapsack problem, which is NP hard, such that we design an approximation algorithm to compute the solution. Through formal proofs and simulations, we verify the validity of the algorithm, which can further improve the QoS of the P2P live streaming.

Meanwhile, a dynamic adaptive method is used in the determination of the jitter threshold. The result of simulation indicates that with the improved algorithm the jitters has been reduced remarkably and other related QoS has also been improved.
