A fuzzy-based data replication system for QoS improvement in MANETs

In Mobile Ad hoc Networks (MANETs), mobile wireless devices communicate together in an autonomous fashion. The transmission is done by multi-hop routes. Because of mobility and limited resources in MANET, it is difficult to guarantee the QoS requirements. In this work, we propose a fuzzy-based system, which improves the QoS of MANETs via data replication. We aim to support critical requirement applications based on MANETs such as disaster management scenarios in which data retrieval is an important requirement to support real time decision making. There are several techniques to optimize data replication strategy for this task. In this paper, we use fuzzy logic and build a system which has three input linguistic parameters and one output linguistic parameter. We evaluate by simulations the proposed system. The simulation results show that the proposed system has a good decision.
