Selection Of Channel-Access And Routing Protocols For Mobile Ad Hoc Networks With Frequency-Agile Radios And Directional Antennas, Rebekah Schloemann
Selection Of Channel-Access And Routing Protocols For Mobile Ad Hoc Networks With Frequency-Agile Radios And Directional Antennas, Rebekah Schloemann
All Theses
In this thesis, ad hoc networks with frequency-agile radios utilizing omni-directional and directional antennas form the basis of study. This work focuses on the selection of channel-access and routing protocols for these networks. Findings demonstrate that protocol selection must occur jointly in order to increase the efficient utilization of available spectrum while achieving maximum network performance.
In this thesis, we investigate several channel-access methods that provide different ways of selecting one of the heterogeneous non-overlapping channels for transmission. We also investigate a modification of least-resistance routing that accounts for the variations in transmission channels. Through simulation, we find that better …

Mitigating Misbehavior In Wireless Networks: A Game Theoretic Approach, Wenjing Wang
Electronic Theses and Dissertations
In a distributed wireless system, multiple network nodes behave cooperatively towards a common goal. Though such assumptions on cooperation are desirable (e.g., controlling the transmit power level, reducing interference for each other, revealing private information, adhering to network policies) for analyzing and modeling, certain nodes belonging to a real-world system have often shown to deviate. These nodes, known as misbehaving nodes, bring more challenges to the design of the wireless network because the unreliable channel makes the actions of the nodes hidden from each other. In this dissertation, we analyze two types of misbehavior, namely, selfish noncooperation and malicious attacking. …
