Area Query Processing Based On Gray Code In Wireless Sensor Networks, Chunyu Ai, Yueming Duan, Mingyuan Yan, Jing He

Faculty and Research Publications

Area query processing is significant for various applications of wireless sensor networks since it can request information of particular areas in the monitored environment. Existing query processing techniques cannot solve area queries. Intuitively centralized processing on Base Station can accomplish area queries via collecting information from all sensor nodes. However, this method is not suitable for wireless sensor networks with limited energy since a large amount of energy is wasted for reporting useless data. This motivates us to propose an energy-efficient in-network area query processing scheme. In our scheme, the monitored area is partitioned into grids, and a unique gray …


A Neutral Network Based Vehicle Classification System For Pervasive Smart Road Security, Naixue Xiong, Jing (Selena) He, Jong Hyuk Park, Donald Cooley Mar 2009

A Neutral Network Based Vehicle Classification System For Pervasive Smart Road Security, Naixue Xiong, Jing (Selena) He, Jong Hyuk Park, Donald Cooley

Faculty and Research Publications

Pervasive smart computing environments make people get accustomed to convenient and secure services. The overall goal of this research is to classify vehicles along the I215 freeway in Salt Lake City, USA. This information will be used to predict future roadway needs and the expected life of a roadway. The classification of vehicles will be performed by a synthesis of multiple sets of features. All feature sets have not yet been determined; however, one such set will be the reduced wavelet transform of the image of a vehicle. In order to use such a feature, it is necessary that the …
