Localized Topology Control in Wireless Networks
… hoc networks as an application of the proposed topology control algorithms, and propose Broadcast on Local Spanning Subgraph (BLSS), which broadcasts in a constrained flooding fashion over the network topology by FLSS. We show that BLSS is scalable, power-efficient, reliable, and significantly …

Game-Theoretic Analysis of Topology Control
… challenges to efficient network design, we study topology control using game theory. We develop a game-theoretic framework of topology control that broadly captures the radio parameters, one or more of which can be tuned under the purview of topology control. In this dissertation, we consider two …
