Consider a wireless link between two IoT devices as shown such that the sender transmits at fixed power of 30 mw when active for 1.5% of the time and is able to deliver throughput to the receiver node at a rate of 20 Kbps. A node consumes 5 w when asleep. Assume transmission energy reception energy and the sleep/wakeup schedules for the two devices are perfectly synchronized. 1) Compute the system energy consumption over a day. 2) Compute the normalized energy consumption over one hour. 3) Compute the system energy efficiency
