dc.description.abstractIn this thesis the design of a low-cost ad hoc network for short distance data acquisition applications with low data arrival intervals will be presented. The focus is on cost reduction by replacing the traditional high power radios with low-power RF transceivers. The conventional way of using multiple stationary repeater towers (depending on the network) is also replaced by using an ad hoc con guration, where each individual station also serves as a repeater station to adjacent stations. This approach reduces network design time enormously, seeing that the network is able to con gure itself. By using this auto-routing multi-hop approach, data acquisition points are no longer restricted to the reception areas of base stations. A CSMA contention protocol is used for the data communication. Current models used to model this protocol are dependent on various assumptions. In the research reported in this thesis, a statistical study of the collision probability is performed and the results used to expand the current CSMA models. Inter-dependent characteristics of this model are also further enhanced to provide a more realistic model. A simulink model of the particular CSMA protocol is also designed. Both the mathematical- and the simulink models provide relatively good predictions when compared to actual measured resultsen_ZA
