1. An Internet of Things (TOT) network system, comprising:
a first subnet, including:
a first wireless base station; and
a plurality of first nodes communicating with one another directly through a second communication protocol, wherein a first specific node of the plurality of first nodes communicates with the first wireless base station through the second communication protocol;
a second subnet, including:
a second wireless base station communicating with the first wireless base station through a first communication protocol; and
a plurality of second nodes communicating with one another directly through the second communication protocol, wherein a second specific node of the plurality of first nodes communicates with the second wireless base station through the second communication protocol,
wherein the first specific node communicates with the second specific node through the first wireless base station and the second wireless base station,
wherein one of the plurality of first nodes generates sensed data and transmits the sensed data to the first specific node through the second communication protocol,
wherein in response to the first specific node processing the sensed data and determining that a surveillance event occurs, the first specific node transmits a warning signal to the second specific node through the first communication protocol, and the second specific node broadcasts the warning signal over the second subnet through the second communication protocol by using the network packet.
