Question 3 ['15 marks) The figure above depicts a personal area network {PAH} which is used to gather information on the average ambient temperature of an area at regular time intervals. N motes are equipped with temperature sensors and organised in a cluster. Consider the following two scenarios: 1. The sensors (circles) periodically report their temperature measurements to the cluster-head of the PAH [trianglel which then relays each measurement to the Sink [square}; the Sink compUtes the average
