The capacity of wireless networks
We show that under optimal circumstances, the throughput is only /spl Theta/(W//spl radic/n) bits per second for each node for a destination nonvanishingly far away. Expand

The Number of Neighbors Needed for Connectivity of Wireless Networks
We show that in a network with n randomly placed nodes, each node should be connected to Θ(log n) nearest neighbors in order that the overall network is connected in a multi-hop fashion. Expand

Optimality of Zero-Inventory Policies for Unreliable Manufacturing Systems
We show that there are ranges of parameter values describing an unreliable manufacturing system for which zero-inventory policies are exactly optimal even when there is uncertainty in manufacturing capacity. Expand

A network information theory for wireless communication: scaling laws and optimal operation
How much information can be carried over a wireless network with a multiplicity of nodes, and how should the nodes cooperate to transfer information? To study these questions, we formulate a model ofExpand

A cautionary perspective on cross-layer design
We show that the conventional layered architecture is a reasonable way to operate wireless networks and is in fact optimal up to an order. Expand
