A throughput based fuzzy system in MANET

Abstract

In mobile ad-hoc network, throughput is very important performance parameter. It depends upon different other network parameters like speed of nodes, pause time, density of nodes. To obtain a desired throughput in mobile ad-hoc network, a fuzzy based throughput calculation work has been performed in this paper. In this work, DSDV routing protocol is implemented in two steps: one is fuzzy based system and another is network simulation based scenarios. Designing the rule based fuzzy system and evaluating the DSDV routing protocol in network simulator work is carried out in this research work. Throughput is considered as main performance parameter for evaluating the table driven protocol. Fuzzy system is designed using one input parameter throughput and four output parameters like pause time, maximum speed, node density, and maximum number of connections. An input will be given by the user and based on that input value; other output parameter values will be calculated by the fuzzy system. In network simulator based scenario, varying the maximum number of connections, maximum speed, pause times, number of nodes, different scenarios were generated and routing protocol’s performance is evaluated.
