Network performance and nodes energy problems are considered as one of the most important aspects of a wireless network based on ZigBee technology. How to prolong the life of ZigBee networks is an important purpose to design ZigBee routing protocol. Based on energy management, ACO-AODV (Ant Colony Optimization-Ad hoc On-Demand Distance Vector Routing) routing protocol can keep the good network performance...
This paper analyzes the signal spectral leak problem of continuous conductivity imaging system of EH-4 after Fourier transform of signals adopted from field surveying under different frequency, which influences the data quality. On the base of analyzing and understanding the characteristics and function of different window functions, combined with the analysis and interpretation on the data during...
As a current main end-to-end communication protocol there are a few vulnerabilities in TCP specification. The paper discusses the theory and vulnerability of TCP persist timer and analyzes the implementation of it in Linux. The vulnerability can lead to the infamous DOS attack. In the end of the paper we give two solutions to defense this type of DOS attack through modifying Linux kernel codes or...
The telecommunication e-Business Navigation System is a typical Information Management System. In this paper a design of the Telecommunication Business Navigation System based on the J2EE has been proposed, which mainly implements the management of the telecommunication company's daily business, such as product information, goods information, AP information, SP information and etc. It uses Structs...
In the embedded field the resolution of LCD is no more than 600??480 pixels by the resource limitation. The article mainly discusses the implementation methods of high resolution of LCD based on ARM-Linux. These methods optimize the system performance and the application with these implementations can support high resolution of LCD, such as 1024??768??16bit@60Hz.
It is very necessary to research the forecasting approach and model for the non-detector intersections flow volume, for large-scale traffic control and traffic-induced the provision of real-time, effective information. This paper presents a comprehensive analysis method based on ridge trace analysis and fuzzy linear regression method. First, take into account the multicollinearity among input variables,...
In this paper, combined with ant colony algorithm, particle swarm optimization algorithm, K-means clustering algorithm, we propose an APSO-K-means clustering algorithm applied to speaker recognition. The algorithm utilizes the strong ability of the ant colony algorithm to process local extremum to avoid the sensitivity to local optimization of the PSO algorithm (APSO). Meanwhile, it utilizes APSO...
