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 point-to-point transmissions between relaying nodes. The origins of this approach are rooted in the practice of traditional wire-line networks. Today, the increasing need to connect a massive number of wireless devices and to support various resource intensive applications necessitates discussing the large system performance of this architecture: Can multi-hop efficiently support communication in large wireless networks or do the people need new architectures for the rapidly growing wireless networks of the future? In particular, can other architectures, tailored more carefully for wireless networks, significantly outperform multi-hop? These are important questions concerning future architectures for such networks.
