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. 2012-08-27T11:33:14Z 2012-08-27T11:33:14Z 2004-10 Thesis http://hdl.handle.net/10019.1/50093 en_ZA Stellenbosch University 103 p. : ill. application/pdf Stellenbosch : Stellenbosch University |
