— This paper addresses the problem of optimizing the packet transmission schedule in a multihop wireless network with end-to-end delay constraints. The emphasis is to determine t...
Facility location problems have always been studied with the assumption that the edge lengths in the network are static and do not change over time. The underlyingnetwork could be ...
Abstract—We present a unified graphical model framework for describing compound codes and deriving iterative decoding algorithms. After reviewing a variety of graphical models (...
It is well known that optimal server placement is NP-hard. We present an approximate model for the case when both clients and servers are dense, and propose a simple server alloca...
We study a generative model in which hidden causes combine competitively to produce observations. Multiple active causes combine to determine the value of an observed variable thr...
