In Mobile Ad Hoc Networks (MANET), Quality of Service (QoS) is an important factor that must be analysed for the showing better performance. The Node Quality-based Clustering Algorithm using Fuzzy-Fruit Fly Optimization Cluster Head and Gateway Selection (NQCAFFFOCHGS) has best network performance because it uses Improved Weighted (IWCA) to cluster FFO algorithm, which fuzzy-based metrics selec...
