As mobile terminals become increasingly sophisticated, the need for robust security also increases. Terminals are moving from simple, voice centric, devices to devices which are capable of multiple functions with multi media capability. Increased capability and the convergence of systems (for example wireless with the internet) bring increased risks. In this article the increase in capability of current and future devices is examined and security issues are observed, considering the large range of terminals - from simple hand-held terminals to more complex, nomadic, laptops or even wireless PCs. In addition the environments within which these devices may operate is considered (and in this document particular attention is paid to the Personal Area Network environment). With wireless devices one of the most important features for secure data transmission is the use of encryption - the basic concept is therefore outlined herein before looking at mobile tracking (a service that might be seen in a similar light to location based services) and finally the article indicates an approach to security for future systems. 相似文献

Mobile sensors have become a connection with more of the new devices and the fast pace. A new group of these devices is a wearable device, wireless sensor networks, and integrating them into sensors and wearable devices is the concept of bringing a new experience to daily living activities. Potential physiological characteristics and training that may affect the strength will contain considerations for improving the expression of maximal expression of Power and limited time. Various factors and strengths related to profit to achieve exercise capacity and great strength. Strong muscle strength contributes to the overall performance improvement of the relevant players in the time characteristics. In the proposed method using K-Nearest Neighbor (KNN)algorithm are using Sports training is physical strength, skill, tactics, psychology, includes the development of intelligence and ability. Physical training is an important part of the training of competitive sports. Physical conditions may also perform directly affects the players. Depletion might not be necessary for the maximum strength benefit of it is not necessary to increase the maximum muscle strength. In practice, programming can combine heavy chains and light loads with improving board strength and power consumption characteristics. Compared to multiple sets, a single set produces excellent training allowances, but the athlete's training status and response relationships must be considered. 相似文献

In response to dramatic changes in the environment, and supported by advances in wireless networking, pervasive sensor networks have become a common tool for environmental monitoring. However, tools for on-site visualization and interactive exploration of environmental data are still inadequate for domain experts. Current solutions are generally limited to tabular data, basic 2D plots, or standard 2D GIS tools designed for the desktop and not adapted to mobile use. In this paper, we introduce a novel augmented reality platform for 3D mobile visualization of environmental data. Following a user-centered design approach, we analyze processes, tasks, and requirements of on-site visualization tools for environmental experts. We present our multilayer infrastructure and the mobile augmented reality platform that leverages visualization of georeferenced sensor measurement and simulation data in a seamless integrated view of the environment. 相似文献
