In this paper, A Urban public transportation positioning system is designed based on overlay network. and its Network topology structure and system framework are also shown, based on the postioning system, it decribles the hardware model of GPRS accessing internet and control programe. and then gives the Transceiver circuit of RF model and control programe. According to the characteristics of buses...
In this paper, A production environment monitoring system based on GPRS-Internet was designed and implemented. The system uses ARM9 embedded CPU as its host and realizes monitoring function and man-machine interface by using cross-platform C++ graphic interface library Qt in Linux OS. It sends collected data to remote server by GPRS model and clients realize real-time and long distance monitoring...
We present a novel lightweight password-based solution that safeguards users from Phishing and Pharming attacks. The proposed authentication relies on a hashed password, which is the hash value of the user-typed password and the authentication server's IP address. The solution rests on the fact that the server connected by a client using TCP connection cannot lie about its IP address. If a user is...
With Ajax firmly established as a widespread Web application-development technique, it is possible to build GPS monitoring system based on B/S architecture, so a large number of Web GPS monitoring systems are released recently. This article analyzes the common GPS monitoring systems based on AJAX and points out three main existing weaknesses. Then the article introduces how to use AJAX push pattern...
"Botnet" is a network of computers that are compromised and controlled by an attacker. Botnets are one of the most serious threats to today's Internet. Most current botnets have centralized command and control (C&C) architecture. However, peer-to-peer (P2P) structured botnets have gradually emerged as a new advanced form of botnets. Without central C&C servers, P2P botnets are more...
As the next generation Internet (NGI) is coming, and with the rapid development and great research progress achieved, mobile Internet Protocol version 6 (MIPv6) based network has become a hotspot all over the world. Considering of the rapid growth of network service quality and data exchange requirement, we are going to propose a new data exchange method in this paper. This method uses resource reservation...
Near-duplicate image detection is a critical task in copyright protection. More challenging than the common similarity search, this task requires not only the retrieval of the top similar images but also the detection of the entire near-duplicates collection from the Internet. The common similarity search algorithms are not capable to undertake the latter demand. This paper proposes the query oriented...
This paper presents a mechanism that automatically build evaluation metadata for grid services by using the information from the execution of different applications. A new MetaService AMDBS, automatic metadata building service, is designed to support this mechanism. The typical feature of this mechanism is that it can get not only the absolute evaluation information, but also the relative global ranking...
