An Efficient Routing in Urban Vehicular Ad Hoc Networks
Xu Liya,Deng Anyuan,Gao Guangyong,Yang Wenzhong,Cheng Yong 보안공학연구지원센터 2016 International Journal of Smart Home Vol.10 No.8
VANET is a highly mobile wireless ad hoc network that is targeted to support road safety, traffic monitoring and other applications. The node communication is easy to break due to the high mobility of vehicles and the road layout. In this paper, we propose an efficient routing based on static node assistance. The static nodes are fixed in each intersection. Each static node stores information of other static nodes in path. The routing takes static nodes as backbone nodes and vehicles as relay nodes between static nodes. The static nodes are selected dynamically and sequentially, and they are chosen according to the delay that packets are forwarded from the current static node to the candidate one. The vehicular relay selection between two static nodes considers the link stability as the parameter. Simulation results show performance improvement comparing with performance of other existing routing approaches.
Parametric investigation on an industrial electromagnetic continuous casting mould performance

This research aimed at conducting a quantitative investigation of process parameters on the magnetic field contribution in an electromagnetic continuous casting mould. The Taguchi method (4 factors and 3 factor value levels: L9 orthogonal array) was adopted to design matrix of the simulation runs and the analysis of variance was used to evaluate the contributions of each control factor. The simulations were conducted based on the finite element method and the numerical set-up was validated by the designed experiment. The results showed that the applied alternating current magnitude contributed most (76.64%) to the magnetic field level in the mould, compared to the other control factors. It was followed by the slit length (17.72%), the alternating current frequency (4.17%) and the slit width (1.57%).
