Rigidity Theory in Joint Position-Clock Estimation for Ultrawideband Sensor Networks

Research overview

Ultrawideband sensors are widely used for distributed sensing in multi-agent localisation for their high accuracy, low price and low computation complexity.  The measurement relies on time-based ranging methods, which necessitates clock synchronisation in the sensor network. Based on graph theory, especially graph rigidity, we proposed a topological condition under which an ultrawideband sensor network can jointly perform localisation and clock-synchronisation. It provides a graph-theoretic approach for designing and implementing position-clock estimators in multi-agent systems.
