Layering of protocols o ers several well-known advantages, but typically leads to performance ine ciencies. We present a model for layering, and point out where the performance pr...
A power optimized space-time code is presented for reliable delivery of layer coded multimedia data through wireless channels. Appropriate power control further improves the perfo...
One central issue in practically deploying network coding is the adaptive and economic allocation of network resource. We cast this as an optimization, where the net-utility
Abstract--Network performance can be increased if the traditionally separated network layers are jointly optimized. Recently, network utility maximization has emerged as a powerful...
In this paper, we propose a general cross-layer optimization framework in which we explicitly consider both the heterogeneous and dynamically changing characteristics of delay-sens...
