Due to the dramatic development of mobile devices and technologies, wireless networks have become a convenient and popular means of accessing the Internet for the public. However, the existing wireless networking techniques still face several fundamental inherent problems, such as network scalability, flexibility, and interoperability. As a result, future wireless communication networking, such as...
The emerging sensor grid that combines WSN (wireless sensor networks) with Grid provides a new way for high energy physics to improve the performance of radiation detection system. In this paper, WSN are utilized to automatically detect the radiation status with high resolution in real-time so as to reduce the radical risk of physicists to the least degree. Further, Grid is combined organically to...
The transmission radius that affects the consumption of energy in WSNs is an important design parameter. In this paper, we define the expected cost of energy as the product of the average hops of packets that sensor nodes intend to transmit to sinks and single-transmission energy consumption. We use mathematical methods deriving a constrained programming model by which the optimal transmission radius...
The attempts to develop a ubiquitous health care monitoring system arisen from the need of automatic real-time medical services for emergent diseases. Besides, the physiological statuses gathered and maintained by this system are very helpful for diagnosis and early warning. To improve the medical services and diagnosis accuracy, a Wireless Health Advanced Mobile Bio-diagnostic System (abbreviated...
