@article{(Open Science Index):https://publications.waset.org/pdf/9998513, title = {A Wireless Sensor Network Protocol for a Car Parking Space Monitoring System}, author = {Jung-Ho Moon and Myung-Gon Yoon and Tae Kwon Ha}, country = {}, institution = {}, abstract = {This paper presents a wireless sensor network protocol for a car parking monitoring system. A wireless sensor network for the purpose is composed of multiple sensor nodes, a sink node, a gateway, and a server. Each of the sensor nodes is equipped with a 3-axis AMR sensor and deployed in the center of a parking space. The sensor node reads its sensor values periodically and transmits the data to the sink node if the current and immediate past sensor values show a difference exceeding a threshold value. The operations of the sink and sensor nodes are described in detail along with flow diagrams. The protocol allows a low-duty cycle operation of the sensor nodes and a flexible adjustment of the threshold value used by the sensor nodes. }, journal = {International Journal of Computer and Information Engineering}, volume = {8}, number = {6}, year = {2014}, pages = {957 - 960}, ee = {https://publications.waset.org/pdf/9998513}, url = {https://publications.waset.org/vol/90}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 90, 2014}, }
