Despite their gross simplicity, random (linear) codes gained great fame with their use in Shannon's 1948 noisy-channel coding theorem. In this talk, we survey three of our applications of these codes to the field of networks. Our first work is a concrete implementation of random coding for over-the-air programming of sensor motes. Our second work relates to fair and secure bandwidth sharing of assymetric channels, where we utilize a game-theoretic framework to craft a protocol resistant to maliciously colluding parties. Our third application involves the use of extreme value theory to predict system-level error rates for wireless broadcast. Each case serves to demonstrate the astonishing power that can be harnessed from these amazingly simple codes.
