In view of the development of the computer network and the vehicle networking technology in the field of transportation, the traffic data which need to be processed in the practical application is explosive. ARM-Linux was proposed based on cloud computing hadoop platform real-time monitoring remote terminal in the big scheme of data analysis and calculation, Hadoop is facing big data computing, open...
We propose AccountTrade, a set of accountable protocols, for big data trading among dishonest consumers. To secure the big data trading environment, our protocols achieve book-keeping ability and accountability against dishonest consumers who may misbehave throughout the dataset transactions. Specifically, we study the responsibilities of the consumers in the dataset trading and design AccountTrade...
For mobile devices, communication via cellular networks consumes more energy than via WiFi networks, and suffers an expensive limited data plan. On the other hand, as the coverage and the density of WiFI networks are smaller than those of the cellular networks, users cannot purely rely on WiFi to access the Internet. In this work we present a behavior-aware and preference-based approach to prefetch...
We study the problem of identifying additive and static link metrics of a set of interesting links in a communication network, by using end-to-end cycle-free path measurements among selected monitors. To uniquely identify the metrics of these interesting links, three questions should be addressed: monitor assignment (which nodes should serve as monitors), paths selection (which cycle-free paths connecting...
A real-time monitor and rescue system must be able to both quickly and reliably detect the event happening in its monitoring region. Furthermore, it is required to fulfill certain rescue mission, e.g., navigate victims to exit through safe path in case of emergency. Current monitor and rescue approaches generally rely on either teleoperated robots, or teams of wireless robots. Typically the robots...
Target tracking is a main application of wireless sensor networks (WSNs), and has been studied widely \cite{tian06RTAS, Bahl2000INFOCOM}. In this work, we study multiple objects tracking problem using WSNs, in which we assume no equipment is carried by the object and the tracking procedure is passive. We first show that without carefully design, Received Signal Strength Indicator (RSSI) and Link Quality...
A kind of embedded smart home system Machine adopted M2M (Machine to Machine) technology is designed, home appliances real-time control and remote communication can be realized. M2M is a new type of data transmission technology, and the most direct communication mode of equipment and equipment. System chose samsung's S3CZ44B0X as MPU, with LINUX operating system, and adopted 3G wireless communication...
Target tracking is a main application of wireless sensor networks (WSNs), and has been studied widely [4], [10]. In this work, we study indoor passive tracking problem using WSNs, in which we assume no equipment is carried by the target and the tracking procedure is passive. We propose to use light to track a moving target in WSNs. To our best knowledge, this is the first work which tracks a moving...
For problems existing in seed-metering device uniformity testing, use photoelectric detection technology on seeding uniformity testing. Its working principle is to use optical sensors to monitor the situation that seeds passing through the seed channel, records the cumulative number of seeds of each channel by counting chips and MCU and periodically send to the PC, obtaining relevant data such as...
In this work, we present a monitor and rescue system utilizing hybrid networks which is a integration of stationary sensor networks and mobile sensor networks: stationary sensor networks comprised of large numbers of small, simple, and inexpensive wireless sensors, and the mobile sensor network contains a set of mobile sensors (robots). The static sensors in our network have “monitoring” ability,...
As it is difficult to previously determine rockmass rheology constitutive model using phenomena methods of mechanics, so a new self-adapting system identification method, a hybrid genetic programming (GP) with the chaos-genetic algorithm (CGA) based on self-rheological characteristic of rock mass, is proposed. Genetic programming is used for exploring the modelpsilas structure and the chaos-genetic...
Aimed at the defects of intelligent electronic household appliances with higher producing cost, and the standard was not unified. This paper analyzed the technical schemes of Embedded Internet in the world at present, combined with the development needs of intelligent community, and used AT91SAM9260 as the host controller, designed a Home Intelligent System which has several merits such as credible,...
