Why each option
IoT networks are characterized by resource-constrained devices and limited bandwidth, which drives their design requirements and protocol choices.
IoT transmission rates are highly variable depending on device type, protocol, and environment - consistency is not a characteristic of IoT networks.
IoT devices are frequently battery-powered sensors and actuators that cannot sustain high energy consumption, so network protocols and hardware must be designed around low power budgets - this is a foundational IoT design constraint.
IoT networks do not use IS-IS for routing; they rely on lightweight protocols such as MQTT, CoAP, and RPL designed for constrained environments.
IoT networks operate in noisy, lossy wireless environments and are inherently unreliable - designs must account for packet loss and intermittent connectivity.
IoT networks commonly operate over low-rate wireless technologies such as Zigbee, LoRaWAN, or NB-IoT, which impose strict bandwidth limitations, requiring efficient and compact data transmission.
