Abstract
Low-power and Lossy Network (LLN) environments may comprise, possibly among other things, different personal area networks (PANs) resulting in, for example, node communication challenges across or between PANs. To address these types of challenges, techniques are presented herein that support a novel secure group management method to self-solve the inter-PAN problem that is both low-cost and customer-friendly. Aspects of the techniques presented herein encompass establishing a secure node-to-node (N2N) communication link between involved inter-PAN nodes, automatically looking for the relay neighbors between different PANs (as the inter-PAN node can help with forwarding the local the Routing Protocol for LLN (RPL) messages), automatically propagating the group information and maintaining the local RPL tree between the inter-PAN nodes, etc. Aspects of the techniques presented herein employ, among other things, spreading PAN advertisement (PA) messages with group and hop information to identify a feasible routing path, using the Extensible Authentication Protocol-Tunneled Transport Layer Security (EAP-TTLS) protocol to establish a secure transport tunnel, automatically unicasting a destination-oriented directed acyclic graph (DODAG) Information Solicitation (DIS) message to join the group tree, etc. Under aspects of the techniques presented herein an application server need not know the topology of a network.
