Abstract
Polling systems were first introduced in the early 1970’s. Polling
system provides performance evaluation criteria for a variety of demand
based, multiple access scheme in computer and communication
systems. Polling systems may be classified into several classes according
to buffer capacity, service discipline, and polling strategy. This
thesis presents an overview for all polling models, putting the emphasis
on applications. Also overview was made on all classifications of
polling systems. We present a complete study on single buffer systems
as a continuous time polling model. This study provides an analysis
for a one message buffer polling system consisting of statistically identical
queues where the reply intervals and the message service times
are generally distributed. Finally we present some numerical results
and the corresponding graphs, on the performance measures for one
message buffer system, and how they are affected by changing different
parameters of the system conditions.
The thesis consists of three chapters: Chapter 1 ”Performance
Analysis”, Chapter 2 ”Polling Systems”, and Chapter 3 ”One Message
Buffer Systems”.
The thesis contains an Appendix on the MIG I 1 FCFS queuing
system and a bibliography including 63 references. We conclude this
thesis by giving a recommendation for future work.
