2023年4月,信息工程学院刘鑫一教授在计算机ESI期刊《IEEE Wireless Communications Letters》上发表了题为“Identification of NLOS Based on Soft Decision Method”的学术论文(DOI: 10.1109/LWC.2023.3240846),论文署名单位为长安大学。
In this experiment, we proposed and implemented a disease forecasting system using a received signal strength indication ZigBee-based wireless network with a 3-axis acceleration sensor to detect illne...
In wireless networks, radio-map based locating tech-niques are commonly used to cope the complex fading feature of radio signal, in which a radio-map is built by calibrating received signal strength (...
A game-theoretic model is proposed to study the cross-layer problem of joint power and rate control with quality of service (QoS) constraints in multiple-access networks. In the proposed game, each us...
A miniature device that combines optogenetics – using light to control the activity of the brain–with a newly developed technique for wirelessly powering implanted devices is the first fully internal ...
Slope movements have caused severe damages of civil infrastructures and numerous human fatalities. Continuous monitoring of slope movements and the collection of vital landslide information are benefi...
A wireless sensor network of nodes with limited energy is considered. The problem of computing a routing flow that maximizes the network lifetime is formulated as a linear program. We consider a conve...
A sensor network of nodes with wireless transceiver capabilities and limited energy is considered. We propose distributed algorithms to compute an optimal routing scheme that maximizes the time at whi...
We consider sensor networks in which individual nodes with on-board sensing and low-power transmitters and receivers establish connections with neighboring nodes. The overall objective is to enable en...
The sensor is a major device in electronics for measuring physical data from the environment. Immense applications in the field of an early warning system in space sciences, atmospheric sciences & aer...
Random key predistribution scheme of Eschenauer and Gligor (EG) is a typical solution for ensuring secure communications in a wireless sensor network (WSN). Connectivity of the WSNs under this scheme ...
Abstract: A two-hop wireless communication link in which a source sends data to a destination with the aid of an intermediate relay node is studied. It is assumed that there is no direct link between ...
Abstract: Interference minimization problem in wireless sensor and ad-hoc networks is considered. That is to assign a transmission power to each node of a network such that the network is connected an...
Abstract: In this paper, we propose a methodology for estimating the statistics of the intercell interference power in the downlink of a multicellular network. We first establish an analytical express...
Abstract: Efficient link scheduling in a wireless network is challenging. Typical optimal algorithms require solving an NP-hard sub-problem. To meet the challenge, one stream of research focuses on fi...
