Energy-Efficient Localization and Tracking of Mobile Devices in Wireless Sensor Networks

Abstract

Wireless sensor networks (WSNs) are effective for locating and tracking people and objects in various industrial environments. Since energy consumption is critical to prolonging the lifespan of WSNs, we propose an energy-efficient LOcalization and Tracking (eLOT) system, using low-cost and portable hardware to enable highly accurate tracking of targets. Various fingerprint-based approaches for localization and tracking are implemented in eLOT. In order to achieve high energy efficiency, a network-level scheme coordinating collision and interference is proposed. On the other hand, based on the location information, mobile devices in eLOT can quickly associate with the specific channel in a given area, while saving energy through avoiding unnecessary transmission. Finally, a platform based on TI C-C2530 and the Linux operating system is built to demonstrate the effectiveness of our proposed scheme in terms of localization accuracy and energy efficiency.

Classifying Arm Movement with Embedded System and Machine Learning

“…As shown in Table 6, when K is 5, accuracy is high. This demonstrates that setting an appropriate K-value is important in AWKNN, as with providing weightings for features that affect class classification [8].…”

Grid Based Sensor Node Deployment Approach for Localization in WSN

“…On another hand, depend on the locality info, mobility devices in eLOT can rapidly associate with the exact channel in a provide region, while saving energy through evading needless communication. Finally, a platform depend on TI CC2530 and the Linux operating system is built to show the usefulness of our define scheme in terms of localization accurateness and energy efficiency [17].

Performance IEEE 802.14.5 and zigbee protocol on realtime monitoring augmented reality based wireless sensor network system

“…Many technologies are invented to make data transfer faster at the same times with powerless [1]- [3]. Communication technology become important because every sensor in each device must transfer data to other devices.…”

“…Nowadays the wireless technology has use less power than normal [3], [8]. This low power wireless technology is produced by Digi Enterprise with their product named Xbee [9]- [11].…”

“…Xbee have two versions S1 with IEEE 802.15.4 and other with ZigBee Protocol. Many devices built with wireless sensor network [1], [3], [8], [12], [13], but there is some problem found because device that built by Xbee must be combined by external devices like Arduino or Micro-controller to maximize the device performance [9]- [11], [14].…”
