Now I use Contiki to develop 6LoWPAN for CC2538. I want to use DTLS for security.
The architecture of DTLS is C/S, so edge router is server and node is client.
My question is whether DTLS can support mesh networks.
For examples, node cannot communicate with other nodes while at stage of neighbour discovery
because all of nodes are client. It means node cannot decrypt ciphertext from neighbour nodes.
What is wrong with me?
Thanks.
