A piece of relevant on-going work, not quite related to routing per se' but very important overall, is the minstrel-blues stuff going on, which couples wifi rate control with power management, so as to use minimum power when transmitting to stations nearby. I have GREAT hopes for that to reduce the impact of there being (in the USA, anyway) a mere 4 people per AP now, a situation that is only going to get worse. http://www.linuxplumbersconf.org/2014/ocw/sessions/2439 patches are in need of review on linux-wireless (I have tested, but we could use more playing with it - Andrew McGregor and I would add a tested-by but I am not on the linux-wireless list presently), and there remains tons of low lying fruit inside wifi left to improve. http://snapon.lab.bufferbloat.net/~d/ieee802.11-sept-17-2014/11-14-1265-00-0wng-More-on-Bufferbloat.pdf I will certainly argue that figuring out the ratio (amdahl's law) energy costs of routing protocol overhead vs actual transmit costs and other costs (like waking up the cpu to do a measurement) would be a good thing. I am very interested in figuring out how IoT devices using FRAMS, in particular, like these: https://plus.google.com/u/0/107942175615993706558/posts/gXH8mrit1Lf http://www.ti.com/lsds/ti/microcontrollers_16-bit_32-bit/msp/ultra-low_power/msp430frxx_fram/overview.page could be made to scale up. Similarly, there are now a VERY low cost set of wifi IoT devices out there, with mind blowing performance and energy characteristics - but I can't remember the name of them right now - 2 bucks in quantity!
