In cooperative localization, minimally constrained system (MCS) refers to the minimal number of global (continuous) constraints which are indispensable for deriving node absolute locations. This paper investigates the optimality and practicability of the MCS. After deriving an optimal MCS and proving that the optimality depends on the node ground truth locations, a geometric approach to construct...
Sensor positioning is a fundamental and crucial issue for wireless ad-hoc local area network operation and management. In this paper, the hierarchical maximum likelihood algorithm for determining the positions of nodes is presented in details. The numerical simulation of the hierarchical maximum likelihood algorithm shows that with no path-loss fluctuation, the localization error decreases with increasing...
