Feasibility Of 802.11a-Based Transceivers For Vhf/Uhf Communications In Remote Regions, Abhimanyu Nath

Graduate Theses & Non-Theses

The project focuses on adapting a traditional IEEE802.11a specification originally designed for indoors, to work across mountainous terrains such as areas of rural Montana in the UHF band. The goal of the project is to experiment with various CSMA/CA timing parameters to accommodate long propagation delays between mountain peaks. The simulation tool was built in C++. When links with various data rates and hidden nodes were introduced during worst case performance analysis, severe packet drops and queue latencies were found in the network statistics. A few timing optimizations were explored and alternatives were considered in the systems design. When stations …
