A mobile ad hoc network (MANET) is a self-contained network made up of mobile nodes that communicate via wireless links. In the absence of a fixed infrastructure, nodes must work together to provide the network functionality that is required. The AODV (Ad hoc On Demand Distance Vector) protocol is one of the most common routing protocols used in ad hoc networks. The AODV protocol's security is jeopardized by a type of attack known as a "Black Hole" attack. A malicious node advertises itself as having the shortest path to the node whose packets it wants to intercept in this type of attack. To reduce the likelihood, it is suggested that you wait and check the responses from all of your neighbors to find a safe route. To combat the Black Hole Attack, we'll use a 'Fidelity Table,' in which each participating node will be assigned a fidelity level that acts as a measure of that node's reliability. If a node's level falls to 0, it is considered a malicious node, known as a "Black hole," and it is removed. In the presence of Black holes, computer simulations using GLOMOSIM show that our protocol provides better security and also better performance in terms of packet delivery than the traditional AODV, with minimal additional delay and overhead.
