Wireless network coding has recently attracted a growing interest due to its potential to improve the performance of wireless networks by taking advantage of the broadcast properties of wireless medium. The talk will focus on two basic wireless network coding problems, index coding and direct data exchange. First, we show a deep connection between the index coding problem, the more general network coding problem, interference alignment as well as the problem of finding a linear representation of a matroid.  Next, we focus on secure direct data exchange between mobile clients in the presence of an eavesdropper. We show that this problem has many interesting reformulations, such as designing constrained generator matrices of MDS codes, and leads to interesting conjectures in algebraic geometry and abstract algebra. Finally, we discuss the game-theoretical perspective of these problems as well as implementation of the network coding technique at the physical layer.
