Target Localization and Tracking Using WSN

With the recent advances in RF and MEMS field, the WSN started playing active role in target LT however, maintaining the LOS is generally a rare possibility especially for indoor environments. Additionally, the localization accuracy of GPS is approximately 2.5 m, which is good for navigation along the road (i.e., for outdoor environment). However, such low localization accuracy is not at all sufficient for indoor L&T applications. Therefore, the research trend is to develop innovative, low cost, and low power indoor targets tracking system, which can overcome the drawbacks of GPS-based systems. The most feasible solution in line with this trend is to use the WSN-based system for target L&T.
