Exercise 6-4 Considering a WSN following the hybrid MAC protocol of (Yang et al. 2009) which implies a super frame of 5 sec of a signaling slot of 0.1 sec and a TDMA slot of 0.1 sec. Suppose a node draws mA when the radio is activated and 0.5 mA when the node is sleeping. We use two AA batteries of 1.6 V and 2000 mAh. There is a superframe every 30 min or 2 per hour. Calculate total current drawn by a non-parent node (only one TDMA slot) in 24 h. Calculate how many days it would take to discharge the batteries
