Abstract
As the number of IoT devices increase exponentially, the importance of betterWiFi energy efficiency methods becomes more and more important. Target Wake Time (TWT) is the newest mechanism mandated by WiFi 6 to making the awake and sleep cycles of devices to be more flexible and efficient by scheduling a time slot for communication. However, as a relatively new technology, it has not been efficiently implemented in its behavior with other pre-existing protocols, namely TCP. TCP uses computed RTT values to guide a lot of its operations, and when RTT is suddenly increased because the TWT operations, TCP mechanisms could become inefficient and even having the connection be closed if the conditions are right. This paper looks at four different scenarios with different duty cycle configurations and RTTs to convey the TCP inefficiencies with TWT enabled. To alleviate the problems with these scenarios, we look into a model where TCP is aware of TWT configurations, adapting RTTs to be more accurate of physical environment conditions.
