Mobile networks (MANETs) and wireless mesh networks (WMNs) are used in a variety of research areas, including the military, industry, healthcare, agriculture, the Internet of Things (IoT), transportation, and smart cities. The swift advancement in MANET technology is the driving force behind this rising adoption rate. Routing over MANET is a critical problem due to the dynamic nature of the link qualities, even when nodes are static. A key challenge in MANETs is the need for an efficient routing protocol that establishes a route according to certain performance metrics related to the link quality. The routing protocols utilised by the nodes in WMNs and MANETs are distinct. Nodes in both types of networks exchange data packets through the routing protocols. For this highly mobile network, the On-Demand Distance Vector (AODV) routing protocol has been suggested as a possible solution. Recent years have attracted researchers' attention to AODV since it is a routing technique for networks that prevents looping. The architecture of this routing protocol considers several factors, including the mobility of nodes, the failure of connection links, and the loss of packets. In this systematic review, one of the key focuses is bringing attention to the classic AODV, which was developed after discussing the recent development of several versions of AODV. The AODV routing protocol performs a path strength check to generate a more reliable and secure route between the source and destination nodes. In AODV, investigations demonstrate advances in both the format protocol approach and the network simulation-2 (NS-2), and these improvements were made in the same scenario used to revitalise AODV. It has been discovered that the AODV is more effective in several aspects, such as throughput, end-to-end delay, packet delivery ratio (PDR), energy consumption, jitter, packet loss ratio, and network overhead. Furthermore, this paper presents this systematic review based on AODV modifications in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). It also provides a methodological framework for the papers' selection.
移动自组织网络（MANETs）和无线网状网络（WMNs）被应用于各种研究领域，包括军事、工业、医疗保健、农业、物联网（IoT）、交通运输和智能城市。MANET技术的迅速发展是其采用率不断上升的驱动力。由于链路质量的动态特性，即使节点是静态的，在MANET上进行路由也是一个关键问题。MANET的一个关键挑战是需要一种高效的路由协议，该协议能根据与链路质量相关的某些性能指标建立路由。WMNs和MANETs中节点使用的路由协议是不同的。这两种类型网络中的节点都通过路由协议交换数据包。对于这种高度移动的网络，已提出按需距离矢量（AODV）路由协议作为一种可能的解决方案。近年来，AODV引起了研究人员的关注，因为它是一种用于防止网络环路的路由技术。这种路由协议的架构考虑了几个因素，包括节点的移动性、连接链路的故障和数据包的丢失。在本系统综述中，一个关键重点是关注经典的AODV，它是在讨论了多个版本AODV的最新发展之后开发的。AODV路由协议执行路径强度检查，以在源节点和目标节点之间生成更可靠和安全的路由。在AODV中，研究表明在格式协议方法和网络仿真-2（NS-2）方面都有进展，并且这些改进是在用于改进AODV的相同场景中进行的。已经发现AODV在几个方面更有效，例如吞吐量、端到端延迟、数据包交付率（PDR）、能耗、抖动、数据包丢失率和网络开销。此外，本文基于系统评价和Meta分析的首选报告项目（PRISMA）中对AODV的修改进行了本系统综述。它还为论文的选择提供了一个方法框架。
