Abstract

Disclosed is a wireless mesh network that includes a first node node and at least one second node. The first node is configured to provide a bi-directional mesh communication to the at least one second node. The first node is configured to broadcast a beacon periodically. The at least one second node is configured to sent a data frame to the first node. The data frame is encrypted by way of an Initialization Vector, which has been composed from at least a first node-specific Super Frame Counter included into the beacon, a Sender-Node-Specific-Frame Counter, and an identification of a sender.
