Abstract: Disclosed are techniques for detecting a security threat in a wireless mesh network. In an aspect, a monitoring device in the wireless mesh network detects a first message transmitted by a source node in the wireless mesh network to a destination node in the wireless mesh network via at least one relay node in the wireless mesh network, collects information from the first message as it is transmitted in the wireless mesh network, determines that the first message has been corrupted based on analysis of the information from the first message, and detects the security threat in the wireless mesh network based on the first message being corrupted.

Abstract: Systems and methods of managing a Bluetooth SigMesh network involve a supervisor configured to monitor one or more network parameters of the SigMesh network, such as topology, message identity, transmit count, transmit interval, relay retransmit count, or relay retransmit interval. The supervisor determines whether one or more of the network parameters are to be adjusted for improving transmission efficiency, reducing traffic congestion, avoiding flooding of packets on the mesh network, or ensuring injection of packets in the SigMesh network. The supervisor provides feedback to one or more nodes with the adjusted network parameters to improve transmission efficiency and reduce traffic in the SigMesh network.
