Encryption is provided through the AES 128 bits algorithm. Specifically through the type AES-CTR. In this case the
Frame Counter field has a unique ID and encrypts all the information contained in the Payload field which is the
place in the link layer frame where the data to be sent is stored.
The way in which the libraries have been developed for module programming means that encryption activation is
as simple as running the initialization function and giving it a key to use in the encryption.

The classic topology for this type of network is Star topology, as the nodes can establish point to point connections
with brother nodes through the MAC address.
