The Performance Analysis and Security Aspects of Manet

Abstract

Mobile Ad hoc NETwork (MANET) is a type of network that is built by connecting a number of mobile devices together in a temporary manner through impermanent connections. Through broadcasting, the information should be distributed to all nodes in the network. A MANET is a network of self-configurable mobile nodes that are connected wirelessly. The security aspect of MANET is a major challenge, and there is a great deal of research being done in this area. The availability of energy is a critical criterion for a decentralised network. The protocol for AODV and DSR routing, as well as the security of the black hole node, are all investigated in this study. Protocols that are used during the route discovery process are particularly vulnerable to attack by the black hole. The goal of this survey, as a result, is to thoroughly investigate black hole attacks while also evaluating the performance of AODV and DSR during black hole attack scenarios. With Network Simulator 3, the work is completed by simulating both protocols under normal operation as well as under a black hole attack. The work is completed with Network Simulator 3 by simulating both protocols under a black hole attack (NS-3). AODV is more vulnerable to a black hole attack than the DSR, according to the results of simulations, and this vulnerability is greater under normal operating conditions. It has been discovered that MANET attacks are carried out with the assistance of a "black hole," according to simulation results.
