Shannon's information theory was a towering achievement of 20th century science and laid a theoretical foundation for understanding how to design communication systems, and to judge their optimality. However, the bedrock assumptions in the Shannon framework of unbounded delay and reliability are not appropriate for mobile ad hoc networks, which has rapidly changing topologies and end-to-end performance constraints. The lack of a descriptive theory for ad hoc networks has greatly impeded their design and commercialization. In response to this roadblock, DARPA has recently initiated a $13.5m Grand Challenge to develop a new information theory capable of describing the performance limits of mobile wireless networks. UT Austin is leading this effort, with one of the two winning proposals, entitled Non-equilibrium
