Abstract: Apparatus, systems and methods for managing wireless devices. A wireless device identifier from an access device is received. An encryption key associated with the wireless device identifier that matches an encryption key stored in the wireless device is identified. The identified encryption key is transmitted to the access device so that the access device can communicate with the wireless device over an encrypted communication channel that is established by use of the identified encryption key and the encryption key stored in the wireless device.

Abstract: In a method for directing packets in a radio network, instances of a packet sent from an origin node to a destination in the radio network are received at each of a set of receiving nodes. At each of one or more of the set of receiving nodes, the received packet is processed by delaying re-transmission of the packet for the delay interval following receipt of the packet. Transmissions of the packet for other nodes are monitored during a delay interval. The node then determines whether to re-transmit the packet according to the monitoring of transmissions of the packet. The node can determine the delay interval from a probability distribution, which can depend, for example, on the progress of the packet to its destination or on signal or link characteristics for the received packet.
