Abstract
In this Scientific Report, we investigate the development of relative localization techniques based on internode distance measurements for small wireless networks where global navigation satellite systems are not available. Internode distance measurement errors are assumed to be small compared to their corresponding internode distances. High precision ranging can be achieved by using technologies such as ultra-wide band (UWB) ranging. A number of approaches are proposed, which include the Linear Least Squares (LLS) approach, the Maximum Likelihood Estimation (MLE) approach, the Map Registration Approach (MAP), the Multidimensional Scaling (MDS) approach and the enhanced MDS approaches. Computer simulations are used to demonstrate and compare the performances and effectiveness of the proposed approaches. Both fully and partially connected networks are simulated for studying the relative localization performance. Finally, conclusions are drawn on the results for relative localization in small networks.
