Abstract

The dynamic nature of Mobile Ad hoc Networks (MANETs) demands a new-fangled set of communication strategies to enhance the performance of Quality of Service (QoS). It is very difficult to find viable QoS routes in MANETs due to its environment. AODV version 2 is called Dynamic MANET On-demand (DYMO) Routing protocol. Drawback of AODV is, it does not support larger networks. DYMO supports both medium and larger networks. To enhance the performance of DYMO, this paper proposes FBNTT DYMO by applying dynamic Node Traversal Time (NTT) in place of defacto NTT using fuzzy logic and Matlab. Fuzzy concept is used by taking network size and mobility is inputs and NTT as output. NTT plays a vital role in improving QoS in MANETs. For the Existing DYMO the default NTT value is 90 ms in QualNet simulator, however in a lively and dynamic environment we should not depend on the static values during protocol configuration. This paper implements FBNTT DYMO using QualNet simulator. The QoS metrics used are: throughput, delay, jitter and First packet received. The experimental result reveals that FBNTT DYMO radically improves the QoS as compared with defacto NTT–DYMO.
