Existing session routing strategies tend to primarily focus on performance and cost efficiency, with less emphasis on energy consumption or sustainability. To address this, devices, systems, methods, and processes that facilitate sustainability-aware collaboration session activity routing are described herein. A session control logic receives attributes of a plurality of network devices and determines sustainability scores for the plurality of network devices. The session control logic further selects a target network device from the plurality of network devices based on the sustainability scores, and directs a collaboration session activity to the selected target network device. Thus, the target network device receives the collaboration session activity in response to its sustainability score being optimal in comparison to respective sustainability scores of peer network devices. As a result, the session control logic explicitly considers sustainability impact of a routing decision when determining routes, leading to improved energy efficiency or reduced environmental impact.

Systems and methods for radio-frequency identification (RFID) are disclosed where session control tasks are offloaded from an RFID reader to a separate device which can take the form of an RFID transmitter such as a session control broadcaster. Accordingly, the RFID transmitter transmits messages to RFID tags to control which of the tags within range of the RFID transmitter are in a readable state and / or unreadable state. These messages can take the form of session control messages, and these session control messages can be targeted to tags of interest. By offloading the transmission of messages that control the readability of tags to a separate RFID transmitter, the system frees up the RFID reader to spend more time on inventory read operations, which reduces the risk that an RFID tag will stay hidden when it briefly exists in a hot spot.
