Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2007. / With the rapid advancement of communication technologies and broadband communication, an
era is starting to emerge where everything and everyone is always connected, regardless of geography.
No other technology has made this more possible than over-the-air data communications
technologies such as Wi-Fi, WiMAX and cellular technologies.
With the possibility of connecting more devices to a common communications network, more
and more applications become available and necessary. One such application is a concept designed
to manage a different type of network; the traffic networks of large metropolitan areas. These
networks carry more traffic with each passing year and the need to manage them fficiently has
become essential. A system to manage traffic networks is an intelligent transport system (ITS),
which integrates all methods of transportation into a single manageable resource. Information
about the current status of the traffic network can be relayed to road users, allowing them to
make informed decisions about alternative routes, or to emergency personnel to inform them of
accidents that occurred on the traffic networks. In order to implement an ITS, a communication
network is required.
This thesis investigates different communication technologies, discussing their merits and
shortcomings in an ITS implementation. A suitable technology is selected and a communications
system is conceptualised. The communications system is an ad hoc wireless network and a routing
protocol used to manage the network, is designed and tested through simulation.
The TH(O)RP routing protocol was developed with a focus on scalability, stability and low
latency in an ad hoc network. TH(O)RP was designed to operate in an ITS environment, where
traffic intersection controllers (TIC) are monitored from a central entity, with optimal routes
between the central entity and the TICs, that can be automatically configured and repaired.
