Wireless sensor networks: from theory to applications

Past

Abstract: Wireless Sensor Network have been an active research area in the past decade. In this work, we will first present our research activities in developing fundamental theories for WSN, including hardware design, node localization, object localization, data transfer and congestion control, real-time services and QoS guarantee technology, and sleep scheduling under large-scale scenarios. In addition, we will discuss our projects on how to apply the WSN technologies in heritage protection and wildlife protection. For the heritage protection, we have monitored environmental data continuously in real-time from the simulated pit of Shaanxi Normal University, the soil site of Tang imperial city wall Hanguang Museum and Xi'an Ming Palace Ruins Dan-feng gate (both with thousand-year-age). Combined with the health status of soil sites, we analyzed the collected data intelligently to explore the intrinsic relationship between the surrounding environment and the soil site. The results can suggest suitable control parameters to protect the site better, and to give experts warning messages promptly. For the wildlife protection, we have monitored the habitat of the golden monkey (Grade 1 National Key Protected Species in China) conservation in the Qinling mountain. By taking advantages of the localization and multimedia transmission analysis technology of WSN, we try to make exploratory study on the golden monkeys activity patterns. Through analyzing the golden monkeys trajectories, it is promising to know their home fields and provide scientific data to support the animal behavior studies.
