Abstract: In one embodiment, a method comprises a network device detecting an event severity encountered by the network device; the network device selectively changing a window size, for a maximum number of unacknowledged data packets that can be sent by the network device to a receiver device, to correspond to the event severity encountered by the network device; and the network device transmitting, to the receiver device, a number of data packets up to the window size, enabling the receiver device to detect the corresponding event severity encountered by the network device based on the number of unacknowledged data packets received by the receiver device from the network device.

Abstract: In one embodiment, an authorizing device (e.g., a gateway) receives a native protocol request packet from a requesting device destined to a serving device, and translates the native protocol request packet into an authorization protocol mapping. The authorizing device may then apply authorization protocol based authorization (e.g., OT protocol independent) to the native protocol request packet based on the authorization protocol mapping, and transmits the native protocol request packet toward the serving device in response to the authorization protocol mapping being authorized. In one embodiment, the techniques herein may also perform an audit in this manner.

Abstract: A system and method for improved location tracking of a target device based on location estimates for multiple types of location technologies/sensor types. A received signal strength location estimate of a target device based on wireless transmissions made by the target device received at a plurality of receiver devices at known locations in a location region. A first search area for the target device is derived based on the received signal strength location estimate. An ultrasound based area in which the target device is estimated to be is derived based on reception by the target device of a particular ultrasound beacon in the location region. An intersection of the first search area and the ultrasound based area is computed to produce a second search area. A location estimate of the target device in the second search area is computed based at least on the received signal strength location estimate.
