aside from using mobility (as per grossglauser/tse), see:
A. Ozgur, O. Leveque and D. Tse, "Hierarchical Cooperation Achieves Optimal 
Capacity Scaling in Ad Hoc Networks",  submitted to the IEEE Transactions on
Information Theory, Sept. 2006 (Revised Feb. 2007).
for an example of a scheme which might work

main problems with cooperation techniques is achieving them in practice may not
be do-able (it reminds me of quantum computing in this regard, full of promises,
but possibly impossible:)
