Abstract
Background:
Because of some inherent characteristics of MANETs such as infrastructural
instability, limitations and shortcomings, multi-hop communication, wireless media and dynamic
topology, routing has emerged as the most important challenge in these networks. This
prompted a wealth of research which attempted to improve the routing quality through focusing
on various qualitative criteria.
Objective:
However, these researches have not adequately addressed the applied characteristics of
MANETs as the most important capability of such networks. In other words, application of these
networks in different fields have warranted the development of different services with varying
Quality-of-Service requirements. This requires the network to support the quality of various services
in proportion with the varying qualitative requirements of transaction services.
Methods:
In order to efficiently address this issue, this research introduces an enhanced protocol
dubbed MMSR-AOMDV based on the development of basic AOMDV protocol and reaping the
benefits of Fuzzy Logic. MMSR-AOMDV is a double-step protocol that attempts to enable distinguishing
transaction services and supporting the various services associated with the specific demands
and requirements of each service based on the performance in each step. For this, MMSRAOMDV
has been developed in a way to enable in the first step the assessment of qualitative indicators
which are associated with the requirements of the services sent via utilizing multi-route
routing and classification techniques, while the second step has been dedicated to offering effective
support for multi-service routing quality thanks to the merits of Fuzzy Logic features.
Results and Conclusion:
The simulation of the proposed protocol using OPNET simulator revealed
that in terms of end-to-end delays, packet lost, network throughput and data reception rate,
MMSR-AOMDV significantly outperformed other corresponding methods.
