    65 The mesh operation is adequately built with a “route discovery” routine since the goal is to send frame (resquest/response) to node in the network. The “route discovery” routine is used to build a route to forward the frame in the network. Once the route is build, the unicast “routing” from the originator to the addressee can be used.
    66 The netflood operation is use to flood all nodes in the network.

    70 All packets are transmitted on the radio channel according to the framing of the IEEE802.15.4 standard (Erreur : source de la référence non trouvée) where the useful packet for the MAC, the MPDU(=PSDU), length is limited to 127bytes.
    71 The frame formats transmitted over the air are summarised here:

     73All packets are transmitted on the radio channel according to the framing of the IEEE802.15.4 standard (Figure 3) where the useful packet for the MAC, the MPDU(=PSDU), length is limited to 127bytes.
     74The frame formats transmitted over the air are summarised here after.

    87 To sink from gateway, the source address is added at its beginning of the APDU, the rest of the frame being unchanged. To gateway from sink, ‘/0’ ascii characters is added at its ending of the APDU.
