Fuzzy Logic Based Trusted Candidate Selection for Stable Multipath Routing

In mobile ad hoc networks (MANETs), providing\udreliable and stable communication paths between wireless\uddevices is critical. This paper presents a fuzzy logic stablebackbone-based\udmultipath routing protocol (FLSBMRP) for\udMANET that provides a high-quality path for communication\udbetween nodes. The proposed protocol has two main phases.\udThe first phase is the selection of candidate nodes using a fuzzy\udlogic technique. The second phase is the construction of a\udrouting backbone that establishes multiple paths between nodes\udthrough the candidate nodes, thus forming a routing backbone.\udIf any candidate node in the path fails due to a lack of\udbandwidth, residual energy or link quality, an alternate path\udthrough another candidate node is selected for communication\udbefore the route breaks, because a candidate node failure may\udlead to a broken link between the nodes. Simulation results\uddemonstrate that the proposed protocol performs better in terms\udof the packet delivery ratio, overhead, delay and packet drop\udratio than the major existing ad hoc routing protocols.\u
