Abstract
In this paper, a fuzzy logic-based Handover Decision System design is proposed that allows for quick, intelligent, and comprehensive decisions during the handover procedure. Many researchers have developed numerou Handover Decision Systems (HDSs) to ensure seamless mobility between different Radio Access Technologies (RATs). However, by increasing the input parameters in available Handover Decision Systems, the algorithm execution time also increases. On the other hand, some algorithms consider mobility parameters a handover decision criterion but lack QoS-related parameters. The proposed design uses a minimum number of fuzzy rules to select the best network for handover and reduce execution time. In addition, a total of eight decision parameters are chosen as the handover decision-making criterion, including QoS, mobility, and efficiency-related parameters. These parameters enhance the intelligence of the decision algorithm and enable a comprehensive decision for performing handover. Simulation results for the current handover decision algorithm in terms of network selection performance show that it is superior to the Simple Additive Weighting, a non-fuzzy logic-based handover decision algorithm.
