Multi-Hop Ad-Hoc Wireless Networks

I am interested in mathematical algorithms useful for the design and the optimization of multi-hop ad-hoc wireless networks, especially with respect to routing, power control, decomposition approaches, etc. Most of these algorithms have to work in a distributed fashion in a real-time environment, so their design can be considered as hard. My work is mainly done in conjunction with industrial partners like Alcatel-Lucent, Bell Labs, Qualcomm, etc.
