Smart network users can use sensing and intelligence to optimise various parameters for their communications as in CSMA channels. Though this paper focuses on energy consumption per successfully transmitted packet as the primary QoS metric, we also examine how the different QoS metrics, such as throughput and delay, also interact with energy consumption, and show how trade-offs can be effected among them. The approach combines a queueing theoretic analysis with the sensing and error control effects in the channel in the presence of interfering communications.
