1. An apparatus for providing signaling for transfer of custody of sensor nodes in a wireless sensor network (WSN), comprising:

  • communications circuitry to interact with a cloud server to receive an instruction regarding a transfer of custody for at least one sensor node within the WSN, wherein the at least one sensor node is assigned to the apparatus for tracking and wherein the instruction identifies a second apparatus within the WSN to assume custody of the at least one sensor node; and

    control circuitry coupled to the communications circuitry to, in response to the instruction, signal the second apparatus and the at least one sensor node regarding the transfer of custody;

    wherein the communications circuitry is further to scan through all channels of the WSN for a ping from an orphan sensor node, and, in response to receipt of the ping, transmit a notification to the cloud server,wherein the instruction, the signal, the ping and the notification are sent over a wireless protocol of the WSN.
