RSSI Based Location-Aware PC Power Management

چکیده
Many existing PC power saving features are under utilized since they may interfere with users’ normal operations of computers. By taking into consideration the locations of computer users, locationaware PC power management techniques can overcome such limitations and offer both energy savings and non-intrusiveness. However, existing locationaware power management schemes either rely on complex location systems for accurate location information or lack the capabilities to support efficient PC power management. In this paper, we present NAPS, a zone based location-aware power management scheme that supports efficient PC power management yet does not require exact location information. In addition, we present our preliminary study on the feasibility of using the received signal strength indicator (RSSI) to estimate zone based locations in an indoor environment. Our experiments using sensor node radios indicate that the RSSI can be used for such purposes.

متن کاملA Novel Weighted Centroid Localization Algorithm Based on RSSI for an Outdoor Environment
Location information is one of the most important services in the field of wireless sensor networks (WSNs). Compared to other proposed non-interactive localization algorithms, the weighted centroid localization scheme only uses the received signal strength indication (RSSI), which makes it simple to implement and robust to variations in the propagation environment. In this paper, we propose a w...
متن کاملReal-time Localization for Wireless Sensor Networks with multiple beacon transmissions
This paper proposes and analyses a localization mechanism for Wireless Sensor Networks. The requirement of the proposed mechanism is the use of a fixed small number of beacon transceivers which will be equipped with GPS functionality and able to transmit a gradient of power levels. The several power levels serve to identify the distance by means of power without using the Received Signal Streng...
