The Center for Real-Time Monitoring and Communications Technologies(CRTMCT), established in 2008, conducts active research on the frontier of computer networks and systems. Major research areas include (but are not limited to) radio-frequency based wireless charging and energy harvesting, wireless passive sensor networks, cognitive radio, mobile internet, wireless communications, and mobile computing. CRTMCT has led and participated in more than 40 research projects, including 863 National Major Projects, 973 Science and Technology Project, National Technology Key Projects, National Science Foundation of China (NSFC)-Guangdong Joint Fund, NSFC, Guangdong S&T Major Project, and research projects supported by enterprises. CRTMCT has built up a high-level professional team consisting of 3 IEEE Fellows, 3 Professors, Chief Scientists and CAS Foreign Distinguished Professor, along with more than 20 technical and supporting staff members.
1.RF based Wireless Charging
Based on RF wireless energy harvesting technology, ultra low power wireless communication system is developed to support the multiband powering. Sensors and wearable devices can work long time without replacing the batteries. The research is expected to solve the energy bottleneck faced by mobile internet and IoT industrial applications, promote the related industries upgrading and development. Relying on this technology, our institute is approved for Shenzhen peacock team “RF based wireless Powering Technology Innovation Team"
2.Mobile Cognitive Radio Network Oriented Spectrum Big Data
The study uses IoT to collect spectrum data, creates spectrum big data system, analyzes and predicts spectrum sharing opportunities. Combining the mobility of network nodes and widely existing potential spectrum accessing opportunities in city, the capacity of the vehicle network are improved and efficient, universal spectrum sharing and communication services are provided to urban mobile cognitive radio networks. This Project was supported by NSFC-United Fund of Guangdong. It hold independent design and development spectrum data acquisition equipment. It can achieve 70MHz-6GHz spectrum scanning.
SpinLight uses infrared LED lamps as signal transmitters, and light sensors as receivers. The main idea is to divide the space into spatial beams originating from the light source, and identify each beam with a unique timed sequence of light signals. This sequence is created by a coded shade that covers and rotates around the LED, blocking the light or allowing it to pass through according to pre-deﬁned patterns. SpinLight presents both 2D and 3D localization designs, demonstrated by a prototype implementation. Experiments show that SpinLight produces a median location error of 3.8 cm, with a 95% of 6.8 cm. SpinLight is very low power and thus can operate for months to years with a button coin battery. A paper describing the work was accepted by a top conference ACM SenSys 2015.
4. Image Forensics
Image Forensics is a promising technique for passive image authentication. It can used to identify camera source, to expose image manipulation, and to detect image tampering by only analyzing the statistical characteristics of images. Our research includes JPEG compression detection, median filtering detection, camera source identification, and so on. In recent years, several studies related to image forensics have been done by our research group.
