The environment consists of the interaction between the physical, biotic, and anthropic
means. As this interaction is dynamic, environmental characteristics tend to change naturally over
time, requiring continuous monitoring. In this scenario, the internet of things (IoT), together with
traditional sensor networks, allows for the monitoring of various environmental aspects such as air,
water, atmospheric, and soil conditions, and sending data to different users and remote applications.
This paper proposes a Standard-based Internet of Things Platform and Data Flow Modeling for Smart
Environmental Monitoring. The platform consists of an IoT network based on the IEEE 1451 standard
which has the network capable application processor (NCAP) node (coordinator) and multiple wireless
transducers interface module (WTIM) nodes. A WTIM node consists of one or more transducers, a
data transfer interface and a processing unit. Thus, with the developed network, it is possible to
collect environmental data at different points within a city landscape, to perform analysis of the
communication distance between the WTIM nodes, and monitor the number of bytes transferred
according to each network node. In addition, a dynamic model of data flow is proposed where the
performance of the NCAP and WTIM nodes are described through state variables, relating directly
to the information exchange dynamics between the communicating nodes in the mesh network. The
modeling results showed stability in the network. Such stability means that the network has capacity
of preserve its flow of information, for a long period of time, without loss frames or packets due
to congestion.
