Abstract
Mobile Ad hoc Network (MANET) is a popular mlobile network that facilitates more emergency services. However, achieving a high quality of service (QoS) and less energy consumption in MANETs remains a challenge owing to their ad hoc nature. To address these shortcomings, this paper designed a stable zone-based 5G clustered MANET environment.. The integration of the MANET with 5G communication aims to yield a high data rate while reducing the latency and cost. This study comprises four major processes, namely, the stable zone-based clustering, Grey-Dematel (GD) gateway selection, adaptive buffer management, and interest-region-based routing. Primarily, mobile nodes are gathered to form a stable cluster, which is vital in frequent topology-changing environments such as MANETs by strawberry optimization algorithm. A gateway is selected to provide 5G multimedia access to MANET users, and the GD algorithm is used to select an optimum gateway (5G user) from among the nearby 5G users of the current CH. The adaptive buffer management (ABM) method is used to reduce congestion in the CH node. ABM manages the buffer through adaptive time division multiple access scheduling, where video files are prioritized over audio/text files. Interest-region-based routing is performed among the users of MANET to reduce the delay and loss. Furthermore, the discrete interval type 2 improved fuzzy function algorithm is used to discover an optimum path in the interest region, which is formed by the angle between the source and destination. The proposed method is implemented using Network Simulator 3.26 (NS3.26). The results indicate that the proposed method improves the packet delivery ratio and throughput metrics by 30% and reduces the end-to-end delay, jitter, and packet loss ratio by 35% when compared to existing methods such as AERP, MCQR, and M-AODV.
