Q6 | How the leader node maintains and migrates the collaborative processing group. Arrange the following steps in correct order a: sensors are selected to acquire new measurements using the sensor selection algorithm b: after the leader is elected, it initializes a belief state as uniform disk centered at its own location c: as the target moves, the sensors that did not previously detect may begin detecting
