| Abstract | The research presented in this thesis consists of the design and investigation into the performance
of a novel hybrid CDMA/CSMA-CD protocol for applications in High Speed Integrated Services Local
Area Networks (HSIS LANs). A class of DSSS protocols which have a true capacity improvement per
unit bandwidth over conventional contention protocols, such as Ethernet, have been identified. CSSS/CD
is used as a generic name describing this class of protocols with various forms of channel sensing and
collision detection. The protocol procedures of Connection, Data Transfer and Disconnection (including
full-duplex capabilities) for High Speed Integrated Services Local Area Networks (HSIS LANs) are
specified. Computer simulation models which can be used to analyse and examine the behaviour of the
CSSS/CD protocols under varying design and operating conditions are devised. These models are built
up using OPNET/M version 2.3 which is a workstation-based network simulation tool conceived by MIL
3 Incorporation. Finally, the delay/throughput performance of the new lP-CSSS/CD protocols are
evaluated and compared with 1 P-CSMA/CD (Ethernet) for identical channel conditions. The advantage
of these protocols is that they may be realised by only a physical layer change to the standard Ethernet
protocol while achieving a true capacity improvement over Ethernet for large offered loads and large data
rates, thus making these protocols ideally suited to HSLN applications |
