The main challenge of the MANET network is the continuous management of information, each device, to ensure the correct direction of traffic. MANET consists of a peer-to-peer connection; the network is self-repairing and at the same time self- formed. The network can be used in the field of road safety, in sensors in the home, healthcare, robotics, etc. The aim of this work was to study the MANET network and its protocols and especially the AODV protocol, the choice of peer in the AODV protocol, and the subsequent improvement of this mechanism. The work deals with ETX metrics and its subsequent implementation in the AODV protocol. The work includes simulations of the AODV protocol and subsequently also simulations of the AODV-ETX protocol. The implementation of the proposed result simulation takes place in Network Simulator 3 tool. The work contains a comparison of the AODV and AODV-ETX protocols. The simulation results are shown in tables and plotted. The AODV-ETX has better properties compared to the AODV protocol, but with a larger number of nodes over 20, these properties approach the AODV protocol. The packet loss, packet delay, and permeability are considered for performance evaluations. 1. Introduction 1.1. MANET Network. An ad hoc network is one in which devices such as computers and cell phones communicate with each other using wireless devices [1–7]. In the MANET network, nodes (laptops, mobile phones, and other wireless devices) can move freely and completely randomly as the topology changes frequently [7–14]. Each node can act as a client and receive information or as a server that sends the provided data over the network. The structure of the MANET network is shown in Figure 1.
