Complex Network Information Exchange in Random Wireless Environments

Abstract : This document summarizes the research performed under AFOSR contract FA9550-08-1-0480, entitled Complex network information exchange in random wireless environments.'' The objective of this project was to develop novel techniques, structures, and algorithms for optimization of complex wireless networks where channels change dynamically and randomly, effecting network performance and reliability. These random dynamics, while challenging for ensuring robust high-performance network operation, also create opportunities that adaptive network control policies can exploit. This is particularly important for advanced military networks operating in rapidly changing, heterogeneous and sometimes hostile environments. A main focus of this research was to develop the new technique of Wireless Network Utility Maximization (WNUM), extending NUM ideas to include network and traffic dynamics. The research also explore optimization of network security protocols that exploit random wireless environments. Finally, compressed sensing and matrix completion ideas were explored to develop low-complexity network control.
