In crossing safety protection system application background, we put forward a radar measurement technique based on adaptive filtering algorithm in order to adapt to the complex environment of level crossings. Firstly, the adaptive learning of the current environment is carried out, and the characteristic values of the noise mean and small signal disturbance are obtained; then the sampling value of...
With the application of wireless sensor networks, many applications not only have ease of installation, reliable data transfer, short-range operation, and extremely low cost and reasonable battery life, whilst maintaining a simple and flexible protocol, but also should have high confidentiality. So the research of the security of the IEEE 802.15.4 is becoming very important. The IEEE 802.15.4 specification...
In the environment of wireless and pervasive computing, wireless storage can provide flexible data access function, data transfer, data collection, and information services, etc. The paper proposes the architecture of wireless storage system, discusses wireless storage system key technologies, and gives performance analysis of it. Later, the paper illustrates related question and some algorithms,...
Mobile grid combines mobile computing and grid computing and develops rapidly. This paper aimed at designing a general architecture of mobile grid, illustrated mobile grid architecture design principle, presented a novel architecture, analyzed the mobile grid constitutes and logical structure. After that we discussed mobile grid resource and service management and allocation mechanism from description,...
Wireless grid is an emerging communication and resource sharing architecture in recent years. It is getting more and more researches and application in mission, industry, business, science research. Wireless grid technique is developing and improving, especially with the storage capacity rising, we can manage storage resources in the wireless grid, and ensure the grid availability and reliability...
