Trend of accelerated aging society increases need of care for the aged at home. To fit this need, we designed the continuous body posture monitoring system based on wireless sensor networks. The hardware platform is made up of anchor nodes, the central control node and wireless sensor nodes which include the three axis low-g accelerometer MMA7260, 2-axis magnetic sensor HMC5883L and CC2431 System-on-Chip...
This paper presents a new method for odor source localization using a Wireless Sensor Network (WSN) by means of collaboration with a mobile robot. The method has two steps: an initial estimation of the position of odor-source is obtained centrally by one robot and is based on particle filtering. It does not require any prior information about the position of the nodes. In the second stage, the nodes...
