A routing algorithm for mobile ad-hoc networks using fuzzy logic and hierarchical tree creation

Mobile Ad hoc Networks) MANETs) have their limitations because of their dynamic topology, absence of fixed infrastructure, and restricted energy resources. This paper therefore presents a new routing algorithm that incorporates fuzzy logic and hierarchical tree topology to overcome these problems. The first step in the proposed algorithm is to identify the weight of nodes in the network depending on factors such as energy level, number of connections, and memory buffer using a fuzzy inference system. These weights are then used to form clusters and then the formation of a hierarchical tree topology is done. This topology is effective in routing performance. The results of experiments show that the proposed solutions increase the efficiency of a network. The packet delivery ratio was increased by 4% while the energy consumption was reduced by 10.03% and end-to-end delay by 16.08% when the proposed algorithm was used instead of previous methods. This improvement is due to the dynamic weighting of nodes by using fuzzy logic and the stability of the hierarchical tree structure.
