The Use of Taguchi Method to Determine Factors Affecting the Performance of Destination Sequence Distance Vector Routing Protocol in Mobile Ad Hoc Networks

In this study, Taguchi method was used to identify the several factors that may affect the performance of Destination Sequence Distance Vector (DSDV) routing protocol. The performance of DSDV routing protocol in mobile ad hoc networks were greatly influence by factors such as node speed, node pause time and traffic load. Problem statement: By using orthogonal experimental design and analysis techniques, the protocol performance can be analyzed with more objective conclusion through only a small number of simulation experiments. Approach: The performance was measured with respect to packet delivery ratio. Analysis of variance (ANOVA) was carried out to identify the significant factors affecting the response and the best possible factor level combination was determined through analysis of the signal-to-noise ratio. Results: It was found that the traffic load has a stronger influence on the packet delivery ratio, followed by the pause time. Conclusions/Recommendations: The optimal setting of the best performance is determined. The optimal setting has resulted in increased packet delivered. These findings demonstrate that Taguchi method may be valuable tool for the investigation of main effect or interactions of multiple factors in the performance of mobile ad hoc network routing protocols.
