Multi-hop is the communication architecture of current wireless networks such as mesh or ad hoc networks. Packets are sent from each source to its destination via multiple relay nodes. Each relay decodes the packets sent from the previous relay and forwards them to the next relay. Can more sophisticated cooperation between nodes significantly increase capacity of such networks? This is an important question concerning future communication architectures for such networks, and information theory has been brought to bear to try to shed some light on this question.
