An EKF based overlapping coalition formation game for cooperative wireless network navigation

Abstract The problem of efficient link selections for cooperative navigation is investigated in dynamic wireless networks, using an extended Kalman filter based overlapping coalition formation (OCF) game approach. Due to the densely deployment of nodes without proper link selections, the conventiona...
