choose a multiple-access protocol that provides the best performance for the following scenarios. Please consider the following protocols: TDMA, FDMA, CSMA/CD, CSMA/CA, Token-passing, and polling protocols. You need to: (1) specify your choice, and (2) briefly justify your answer. (a) (2 points) 10 smart home devices (say, TV, ring camera, etc) are connected to your home WiFi. Some devices have heavy data to transmit (e.g., video streaming, >10Mbps) and some devices rarely have traffic to transmit (e.g., Nest Thermostat, < 1KB per 24 hours). (b) (2 points) 10 IoT sensors (say, temperature sensors) are deployed in the field (say, 100 m x 100m area). They all are connected to a sink via wireless (which can be bluetooth, LoRa or any wireless medium). Each IoT sensor rarely has data to transmit (say, < 1KB per 24 hours).
