Design and Analysis of Wireless Networks: Connectivity, Coverage, and Capacity

In the second part of this dissertation, we study how fading, a fundamental aspect of all wireless communications, influences the scaling of the transport capacity of wireless networks. The transport capacity is the supremum of the sum of distance-rate product over all source destination pairs. Our results show that in the high attenuation regime when the absorption constant of the medium is positive or the path-loss exponent is larger than 3, the transport capacity scales as theta(n), whenever every pair of nodes is separated by at least a constant distance. This is true in various fading environments and for any causal strategy. This fundamental result shows that the current technological strategy of relaying by repeated decode-and-forward is order optimal even in the presence of fading.
