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

• Wireless Sensor Networks are networks that consist of sensors that are A: distributed in an ad hoc manner. B: These sensors work with each other to sense some physical phenomenon and then the information gathered is processed to get relevant results. C: Wireless sensor networks consist of protocols and algorithms with self-organizing capabilities.
• Node gather enough anchor points and measurements, they compute their own locations. Once they have localized, they also declare themselves as an anchors. In this way, sensor nodes without enough anchors get a chance to localize. This approach is called as ____________ localization.
