Over the past few years there has emerged a network information theory motivated by the twin goals of applicability as well as tractability vis-a-vis the rapidly emerging field of wireless networking. A central aspect of this theory is that the spatial aspects of the system, including locations of nodes and signal attenuation with distance, are explicitly modeled. Also, distance is intimately involved even in the performance measure of transport capacity that is analyzed. This theory has been used to develop bounds on the distance hauling capacity of wireless networks, feasibility results, scaling laws for network capacity as the number of nodes increases, and also suggest ...
