Automatic and real-time monitoring of the deformation and instability of slopes and crags is an effective means to predict landslide and other geological disasters. It helps grasp the disaster rules, make a timely qualitative or quantitative safety evaluation, and minimize the disaster occurence and damage. The ZigBee-based WSN (Wireless Sensor Network) technology was used to real-time sample and...
Current society, Emergency Management System (EMS) widely uses Wireless Sensor Network(WSN) to assure safety. If emergency happens, in dynamically changing environment, real-time property of emergency information should be assured. But conventional approaches which are based on static situations and centralized management can not satisfy this requirement. Thus, we introduce community. Community is...
Wireless Sensor Network (WSN) is widely used in Emergency Management System (EMS) to assure requirement of safety. If emergency happens, real-timely transmitting emergency information in dynamically changing environment should be assured. Therefore, community is introduced to solve this problem. In this paper, to achieve high assure, autonomous community coordination technology is proposed. Each community...

In this paper, we present a practical wireless sensor network for environmental monitoring (OceanSense) deployed on the sea. The system is mainly composed of TelosB motes, which are deployed on the surface of the sea collecting environmental data, such as temperature, light and RSSI from the testbed. The motes communicate with a base station, which transmits collected data to a visualization system...
In this paper we discuss a novel multihop transport scheme for wireless sensor and actor networks (WSAN) that facilitates (a) reliable multihop data packet transmission from the sensor nodes to a centralized controller (sink), and (b) reliable multihop control packet transmission from the sink to different actor nodes. The transport scheme works on a model of prioritized packet store-and-forward mechanism...
Radiofrequency identification (RFID) technology has been adopted in various supply chain management applications because of its fast and low-cost ability to identify items uniquely. In this paper, we consider the integration of a wireless sensor network (WSN) with RFID to provide item-level inventory monitoring in retail stores. First, we present a basic formulation for RFID-based item-level inventory...
