Overview
Topic status: We're looking for students to study this topic.
Wireless is now a pervasive aspect of everyday life, and has become ubiquitous. This makes it possible to develop emerging and location-aware services that cannot be provided by existing network systems. Potential applications of location-aware services include emergency services, aged care and assisted living, to just mention a few. Although the Global Navigation Satellite Systems (GNSS) are an ideal positioning technology for open sky operation, they have limited availability in urban settings, especially in indoor applications, due to the blockage of signals. Preliminary studies have shown several possible solutions using wireless networks for positioning services. One is to use access points; however, noise characteristics will result in inaccuracy in location determination. An alternative and distributed solution is to establish relative clocks of the mobile nodes; however, accurate relative clocks and their synchronization in wireless networks are still challenging. Addressing both challenges, the projects to be carried out on this topic aim to develop effective technologies for accurate location determination in wireless networks. Specific objectives include:
- Comprehensive requirements analysis for wireless location determination;
- Development of fast and precise relative clock synchronization protocols
- Development of innovative methods, algorithms, and protocols for wireless location determination; and/or
- Evaluation and demonstrations of the developed technologies.
