1. A computer-implemented method for securing a wireless mesh network of beacon devices, comprising:

  • receiving, by a master beacon device and from a plurality of servant beacon devices in a mesh network, survey data comprising, for each of the servant beacon devices, a beacon device identifier and path loss information of proximate servant beacon devices detected by each servant beacon device;

    transmitting, by the master beacon device and to each of the plurality of servant beacon devices, enrollment data comprising beacon device identifiers and corresponding path loss values of proximate beacon devices to servant beacon devices determined from the received survey data, wherein the enrollment data may be retransmitted by servant beacon devices within the mesh network to reach other recipient servant beacon devices;

    receiving, by the master beacon device, authentication data from a plurality of servant beacon devices, the authentication data comprising beacon device identifiers for servant beacon devices and path loss information detected by servant beacon devices of proximate servant beacon devices;

    comparing, by the master beacon device, the received survey data to the received authentication data; and

    determining, by the master beacon device, that the mesh network is insecure based on identified differences between the path loss data from the received survey data and the path loss data from the received authentication data.
