Distributed optimization and market analysis of networked systems
(Massachusetts Institute of Technology, 2014)
In the interconnected world of today, large-scale multi-agent networked systems are ubiquitous. This thesis studies two classes of multi-agent systems, where each agent has local information and a local objective function. ...
Model-code separation architectures for compression based on message-passing
(Massachusetts Institute of Technology, 2015)
Data is compressible by presuming a priori knowledge known as a data model, and applying an appropriate encoding to produce a shorter description. The two aspects of compression data modeling and coding - however are not ...
Towards security without secrets
(Massachusetts Institute of Technology, 2016)
Physical Unclonable Functions (PUFs) are a promising new cryptographic primitive that leverage manufacturing variation to create unclonable secrets in embedded systems. In this case, the secret is no longer stored permanently ...
Network localization and navigation : theoretical framework, efficient operation, and security assurance
(Massachusetts Institute of Technology, 2014)
Reliable and accurate localization of mobile network nodes is a key enabler for numerous emerging applications in the commercial, public safety, and military sectors. Achieving such location awareness by conventional ...
Application workload prediction and placement in cloud computing systems
(Massachusetts Institute of Technology, 2014)
Cloud computing has become popular in recent years. Companies such as Amazon and Microsoft host large datacenters of networked machines available for users to rent. These users are varied: from individual researchers to ...
The value of field experiments in estimating demand elasticities and maximizing profit
(Massachusetts Institute of Technology, 2014)
In many situations, the capabilities of firms are better suited to conducting and analyzing field experiments than to analyzing sophisticated demand models. However, the practical value of using field experiments to optimize ...
Fast in-memory storage systems : two aspects
(Massachusetts Institute of Technology, 2014)
This dissertation addresses two challenges relating to in-memory storage systems. The first challenge is storing and retrieving data at a rate close to the capabilities of the underlying memory system, particularly in the ...
The role of control information in wireless link scheduling
(Massachusetts Institute of Technology, 2015)
In wireless networks, transmissions must be scheduled to opportunistically exploit the time-varying capacity of the wireless channels to achieve maximum throughput. These opportunistic policies require global knowledge of ...
Super-efficient rational proofs
(Massachusetts Institute of Technology, 2014)
Information asymmetry is a central problem in both computer science and economics. In many fundamental problems, an uninformed principal wants to obtain some knowledge from an untrusted expert. This models several real-world ...
Hardware-level fine-grained thread migration
(Massachusetts Institute of Technology, 2014)
Although thread migration has long been employed to satisfy load-balancing goals in operating systems for symmetric multiprocessing hardware, the high cost of OS-mediated migration has made more fine-grained applications ...
