MANET (mobile ad•hoc network) is a wireless ad•hoc network made up of mobile devices that use peer•to•peer routing to provide network access instead of using a preexisting network infrastructure. Despite the network infrastructure’s simplicity, it faces issues such as changeable connection capacity, dynamic topology, node battery power exhaustion, and inadequate physical security. Broadcasting is a standard MANETapproach for sending messages from a source node to all other nodes in the network. Flooding is a frequent method for broadcasting route request (RREQ) packets, which is susceptible to broadcast storms. Te high retransmission rate is caused by the standard fooding technique, which causes media congestion and packet collisions, which can drastically reduce throughput and network performance. In a mobile ad•hoc network, efcient broadcasting focuses on selecting a compact forward node set while assuring broadcast coverage. Te goal is to fnd a limited number of forward nodes that will provide complete coverage. In this paper, we propose an optimized and energy•efcient routing protocol for MANET (mobile ad• hoc network) based on dynamic forwarding probability in general and AODV (ad hoc on•demand distance vector) in particular, in which the route request packets are randomly controlled to increase the network lifetime and reduce packet loss in the fooding algorithm. We tested and assessed the results of our proposed solution using various network performance factors after implementing and integrating it into NS•2. According to simulation fndings, our proposed technique efectively reduced route request propagation messages (RREQ). Te suggested technique is more efcient, has a longer network lifetime, and uniformly utilizes node residual energy, enhancing network throughput and minimizing routing overhead when compared to regular and modifed AODV protocols. 1. Introduction Wireless networks can be categorized mainly into two groups such as infrastructure•based and infrastructure•less networks. In infrastructure•based networks, all the nodes are controlled by a centralized access point or base station; whereas, the nodes communicate with each other through multiple links without any centralized monitoring system in infrastructure•less networks (i.e., ad hoc network). Trough the advancements in wireless communication and economy, portable computing devices have made mobile computing possible 1]. MANET (mobile ad•hoc network) consists of a set of mobile nodes (hosts) that are connected by wireless links. Te network topology (the physical connectivity of the communication network) in such a network may keep changing randomly. Routing protocols that fnd a path to be followed by data packets from a source node to a destination node used in traditional wired networks cannot be directly applied in MANET due to their highly dynamic topology, Hindawi Journal of Computer Networks and Communications Volume 2022, Article ID 5750767, 13 pages https://doi.org/10.1155/2022/5750767
