Abstract

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 attempt to deliver packets across the network, they benefit from adapting their timeout periods so as to accommodate long round-trip times while waiting for their response. Upon applying all optimizations in the source code, network performance greatly improved and thereafter, statistics were recorded to show the benefits of using Wi-Fi protocol within 50 km of coverage.
