Thesis (MScEng)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: This thesis investigates and develops some aspects of low speed wireless telemetry applications.
The system configuration is one of a single master, controlling and communicating
with multiple slave stations over a radio network. The aim of this thesis is to develop a
narrow band wireless communications network based on a protocol with slotted time base,
utilizing standard, off the shelf hardware. The idea is to investigate different strategies
for improvement of data throughput performance under conditions of both low- and high
loading, using this basic protocol. Such strategies may, amongst others include collision
detection, flow control and pre-scheduling algorithms.
This thesis will also show the how the non-adaptive system's data throughput performance
can be improved using an adaptive system under low- and high loading. Half-duplex
communication mode will be used for data communication. / AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek en ontwikkel sommige aspekte van laespoed radiotelemetrie toepassings.
Die stelselkonfigurasie is een van 'n enkel meesterstasie wat met 'Il aantal buitestasies
kommunikeer oor 'n radionetwerk. Die doel van die tesis is om 'n tydgegleufde protokol
te ontwikkel vir nouband radiotoepassings, deur gebruik te maak van standaard, maklik
beskikbare hardeware. Die doel is om verskillende benaderings te ondersoek vir die verbetering
van datadeurset onder toestande van beide hoë- en lae belading. Sulke strategieë
mag botsingsdeteksie, vloeibeheer en voor-skedulering insluit.
Die tesis salook aandui hoe die data deurset van die nie-aanpasbare metode verbeter
kan word, deur gebruik te maak van 'n aanpasbare metode vir beide beladingstipes. Die
kommunikasiestelsel is half-dupleks gebaseer.
