Reference node selection for cooperative positioning using coalition formation games

摘要

Selective choice of cooperating nodes leads to decrease of error propagation while reducing power consumption at the same time. Our approach to the node selection problem consists in modeling the localization process as a cooperative game. From the localization accuracy point of view, observations may be highly correlated in space domain. In that sense, we propose a node selection scheme to avoid collection of redundant information and thereby reduce the number of necessary measurements.
