Reducing communication in sparse solvers
… of these operations is limited by irregular point-to-point communication. Multiple methods are investigated throughout this dissertation for reducing the cost associated with communication throughout sparse matrix operations. Algorithmic changes reduce communication requirements, but also …

Relay-aided communications with partial channel state information
Modern wireless communication systems strive to enable communications at high data rates, over wide geographical areas, and to multiple users. Unfortunately, this can be a daunting task in practice, as natural laws governing the wireless medium may hinder point-to-point transmissions. …

Performance Tuning and Modeling of Communication in Parallel Applications
… However, in- troducing parallelization to an application also introduces synchronization and com- munication overhead, which in turn creates a performance bottleneck. Performance modeling and tuning can be used to predict and ease this bottleneck to improve the overall performance of the …

Multiple reflector scanning antennas
Narrow beamwidth antenna systems are important to remote sensing applications and point-to-point communication systems. In many applications the main beam of the antenna radiation pattern must be scannable over a region of space. Scanning by mechanically skewing the entire antenna assembly is …

Correlated Sources In Distributed Networks - Data Transmission, Common Information Characterization and Inferencing
… source and channel coding is optimal for point-to-point communication. However, this is not the case for multi-terminal communications. In this thesis, we study the problem of communicating correlated sources over interference channels (IC), for both the lossless and the lossy case. For …

Selfishness and Malice in Distributed Systems
… In this dissertation, we provide algorithms to address both of these issues. One approach to ameliorating selfishness in large networks is the idea of a mediator. A mediator implements a correlated equilibrium when it proposes a strategy to each player privately such that the mediators …
