Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2005. / The Automatic Position Reporting System (APRS) is a well-established packet communication
protocol that offers users a graphical position display system and a peer-to-peer
textual message service. APRS is used in temporary and mobile networks where rapid
deployment of infrastructure is required and limited a priori knowledge of the network
topology is available. The APRS protocol can be used for emergencies and public service
applications.
ARPS, functioning as an access network, was originally designed to require low complexity
and support high flexibility of a network. These design directives have limited APRS’s
performance by resulting in low throughput and poor reliability. In order for APRS to be
used in time-critical applications, these limitations would need to be improved.
The thesis considers the limitations of ARPS by proposing an improved protocol stack
with a substitution of the media access control (MAC) layer. The new protocol is modelled
in order to develop a largely platform-independent implementation, which could be
efficiently retargeted for different platforms. Lastly, a protocol performance evaluation is
done in order to determine the resulting improvements on APRS and the overall viability
of the proposal.
