Received signal strength indicator (RSSI) is not suitable for fine-grained indoor applications because of imprecise and unreliable readings caused by multipath fading. This paper presents a simple and robust mechanism to improve RSSI by mitigating multipath fading effects in an indoor environment. Signal analysis is provided to explain the rationale of this method. The proposed method provides instantaneous...
The real-time monitoring about the activity of the human provides useful information about the activity quantity and ability. The present study implemented a small-size and low-power acceleration monitoring system for convenient monitoring of activity volume and recognition of emergent situations such as falling during daily life. For the wireless transmission of acceleration sensor signal, we developed...
With the advancement in the wireless sensor network technologies, it is possible to use them for health monitoring from remote location. The monitoring of human movement can provide valuable information about individual's daily activities. Wireless sensor node with 3-axes accelerometer were used to monitor daily activities i.e. walking, running, resting and dangerous activities such as falling. Three...
