WiFi continues to be a prime source of energy consumption in mobile devices. This paper observes that, despite a rich body of research in WiFi energy management, there is room for improvement. Our key finding is that WiFi energy optimizations have conventionally been designed with a single AP in mind. However, network contention among different APs can dramatically increase a client's energy consumption. Each client may have to keep awake for long durations before its own AP gets a chance todoi:10.1145/1999995.2000020 dblp:conf/mobisys/ManweilerC11 fatcat:y3ahebnfm5fppj44ok57r5e62y
