Abstract—Existing work on cross-layer optimization for wireless networks adopts simple physical-layer models, i.e., treating interference as noise. In this paper, we adopt a dete...
— We consider a network of n sender/receiver pairs, placed randomly in a region of unit area. Network capacity, or maximum throughput, is defined as the highest rate that can be...
A sender wishes to broadcast a message of length n over an alphabet of size k to r users, where each user i, 1 i r should be able to receive one of possible mi messages. The cha...
Abstract--Two types of noise-free relay cascades are investigated. Networks where a source communicates with a distant receiver via a cascade of half-duplex constrained relays, and...
We consider a wireless collision channel, shared by a finite number of users who transmit to a common base station. Each user wishes to minimize its average transmission rate (or p...
