XPS: FULL: CCA: Collaborative Research: Automatically Scalable Computation

For over thirty years, each generation of computers has been faster than the one that preceded it. This exponential scaling transformed the way we communicate, navigate, purchase, and conduct science. More recently, this dramatic growth in single processor performance has stopped and has been replaced by new generations of computers with more processors on them; […]

CIF: Small: Quantization for Acquisition and Computation Networks

Networks of sensors are increasingly important in a variety of applications including national security, environmental monitoring, and health care. These systems should serve their purposes with minimal communication between sensors and minimal computation overhead from coding. In particular, these efficiencies can dramatically improve battery life, and in systems such as those implanted in a body, […]

CIF: Small: Collaborative Research: Exploring Synergies of Multi-State Networks

The objective of this project is to undertake a comprehensive study of synergistic gains for multi-state communication networks and develop strategies that can exploit them. The project is organized into three complementary thrusts, focusing on 1) dynamic channels, 2) dynamic channel knowledge, and 3) mixed channel knowledge. The first thrust seeks ways to exploit channel […]

CIF: Medium: Collaborative Research: Interference-Aware Cooperation via Structured Codes: Creating an Empirical Cycle

The classical approach to wireless communication is to isolate communication links by maximizing signal strength and minimizing interference between users. This simple philosophy is supported by a rich theoretical foundation which has inspired powerful coding techniques and protocols that lie at the heart of modern wireless systems. However, these systems have recently become victims of […]

CAREER: Harnessing Interference Structure in Networks

Wireless networks are the fabric of the mobile Internet. High-speed, ubiquitous wireless access is increasingly an enabling technology for important applications ranging from communication to commerce, medicine, and education. It is thus critical to create a pathway for sustainable wireless network growth in terms of the number of users and their data rates. A major […]

CIF: Small: Sensing-Aware Decision Making for High-Dimensional Signals

There has been an explosion in our ability to sense and record the world around us. This has led to new discoveries and allowed us to consider new paradigms in nearly every walk of life. While the promise of these developments is significant, the explosion of sensing has also created substantial challenges. These challenges include […]

NeTS: Small: Understanding Communication Strategies for Ad hoc Networks

Ad-hoc networks hold great promise, but there is a vast array of competing proposals for organizing such networks. Unfortunately it is unclear, in general, how to choose among the various proposed designs in any given deployment. In response, this project is asking a fundamental question: how should a collection of nodes decide what basic architecture […]

NeTS: Small: New Directions in Network Dimensionality Reduction for Routing and Beyond

Many important problems in computer networking depend on the observed properties of network graphs — graphs obtained by measuring real network. These include networks of routers, autonomous systems, wireless nodes, and social relationships. Unfortunately, despite the explosion of detailed data now available, such graphs are still poorly understood, in part because of the high dimensionality […]
