MANETs (Mobile Ad Hoc Networks) are widespread today and are becoming a popular research topic.The wireless ad hoc network is another name for it.MANET is a portable multi-hop network with no infrastructure.In a MANET, data is transmitted to victims of mobile devices.These mobile nodes have no restrictions on their movement within a network.When a source node in a MANET needs to send or transfer data to a destination node, it first initializes the route to the destination node and then forwards the packets along this route.The intermediate nodes help transfer data packets from the source to the destination.However, due to the presence of malicious or misbehaving nodes such as black holes (BH), MANET data transmission is vulnerable to both internal and external attacks.MANET routing protection becomes a major problem as malicious or misbehaving nodes disrupt routing and result in significant loss of sensitive and confidential data.The main attack on MANET is the attack on the black hole.The aim of this document is to target the black hole attack using the SETRP (Secure and Efficient Transmission Routing Protocol) to identify and eliminate faulty nodes and to evaluate the efficiency of the network based on parameters such as average power consumption and service life of the network and the residual energy.In addition, we measured the effect and appearance of a black hole attack on the network based on the number of mobile nodes and the cumulative number of black nodes.Further investigation can be done by removing network parameters and applying a prevention strategy to avoid black hole attacks.
