Abstract

Mobile Ad hoc Network (MANET) attracted many proficient researchers because of its various features. In MANETs, routing is a challenging issue because of route changes and link breaks. Among the reactive routing protocols in MANETs, Dynamic MANET On-demand (DYMO) routing protocol is selected because it is scalable for larger networks and it has less routing overhead. Drawback of DYMO routing protocol is that it does not support for smaller networks with low mobility speed. In this paper, we apply Taguchi Design of Experiments approach to identify the most significant factor that enhance (Quality of Service) QoS performance of DYMO routing protocol for smaller networks with low mobility by considering Route Request Wait Time(RRWT),Route Timeout(RT), Route Request Retries(RRT)as influencing parameters of DYMO routing protocol. The impact of three influential factors on two QoS performance metrics i,e Average Throughput and Packet Delivery Ratio has been evaluated. The experiments are run on NS2 simulator and the results are analyzed through Statistical tool Minitabusing Main Effects Plot, Response Table and validated using Normal probability plot of Residuals, Residual Histogram, Residuals vs Fits, Residuals vs Order. The Route Request Wait Time (RRWT) is identified as the most significant factor among the other factors for enhancing QoS of DYMO routing protocol for smaller and medium network sizes.
