  Generally, combinatorial design concerns with the arrangement of a finite set
of elements into patterns (subsets, words, arrays) according to specified
rules. The usefulness of this design method is that the number of input
combination can be reduced dramatically but all of them are covered by the
combinatorial set. This paper presents the application of this design method in
communication networks. Communication engineers can use this novel method to
generate test cases for producing a cost-effective set of experiments to
recognize the factors that have the least and most impact on the system's
performance. A well-known scenario is used for the purpose of the experiment
and five factors with different values are chosen to qualify their effect on
the network performance. The experimental set is generated using combinatorial
design method and then it is been used to analyze the effect of each factor.
The experiments showed the effectiveness of the method to be used for analyzing
the effect of factors on the communication network.
