A novel sensor deployment method utilize Discrete wavelet transform (DWT) is proposed, and the DWT is used to calculate the sub-band energy entropy to ascertain the coverage cavities in Wireless sensor networks (WSNs). We address the problem of deploying a limit number of sensors to optimize the coverage ratio in 3D surface, while it is a complex surface in space and sensors can be deployed only onto...
The cluster head is selected by the random number generated by nodes in the hierarchical routing protocol which is implementing Low Energy Adaptive Clustering Hierarchy (LEACH). As a result, the cluster head may be chosen randomly and be distributed asymmetrically. Focus on this problem, this paper introduces a function to improve the problem. This function uses the relative distance between nodes...
Through analyzing the applied require for millimeter wave automotive anti-collision radar, we design the simple structure of radar system. For satisfying the demands of digital signal processing and dispatching affairs, the signal processor is designed by linking DSP and SCM. Considering the complexity of radar signal received, high efficient digital signal processing algorithms should be applied...
The multi-disciplinary modeling and collaborative simulation of multi-robot systems (MRS) based on High Level Architecture (HLA) is presented. The major constitutions of this system - the HLA, the modeler, the simulator and the database - are described in this paper, whose implementation and functions are discussed in detail. This paper also introduces further refinements of this system. According...
Aiming at realizing the aircraft engine test visualization in the test link, we have done research and development on gas turbine engine test visualizations using configuration method. In this paper, a set of aircraft engines test visible plan is introduced. In this paper, the plan has used the advanced object-oriented thought to build basic module, and configuration design technology has been fully...
