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 …
