Question 5 [Total 25 Marks] -- a) b) i. Sketch and discuss the Zigbee architecture to demonstrate the main components of the system. [10 Marks] Consider the blood-pressure sensing node in the Zigbee network that works on a 2 V battery with a capacity of 50mAh. Usually, a Zigbee node is to last 3 years on this battery. If the node is operated continuously, Determine the power in appropriate units that can be consumed by the node. [3 Marks) Assume that node can turn off its transceiver to reduce the power consumption by 80%. This indicates that the node only consumes 20% of the power when the transceiver is not operating. If the node can use sleep modes to keep the transceiver on only 10% of the time, how much longer will the battery life become? [3 Marks ii. co Zigbee is implemented either as non-Beacon-based network or as Beacon-based-network. Compare both network setups and discuss which of these is advantageous for acquiring and analysing data in case of oil and gas industry
