Mamdani Fuzzy Control based adaptive gateway discovery for ubiquitous Internet access in MANET
Rafi U. Zaman, Khaleel Ur Rahman Khan, A. Venugopal Reddy · 2014
Ubiquitous Internet access has become a reality with the proliferation of mobile devices. One of the architectures which have the potential to abet ubiquitous Internet access is the Integrated Internet-MANET architecture, which is an interconnection of the wired Internet with wireless MANET. Gateway discovery and gateway load balancing are important issues in Integrated Internet-MANET and have been addressed separately in the literature. In this paper a new solution which addresses these two issues together is proposed. In the proposed mechanism, the problem of finding efficient values to gateway discovery parameters is treated as a control system which uses the Mamdani Architecture for Fuzzy Control. Gateway load balancing is achieved through the WLB-AODV routing protocol. The proposed protocol has been simulated in ns-2 network simulator. Simulation results show that the proposed protocol gives better packet delivery ratio and comparable end to end delay to the existing solution.
