A mobile ad-hoc network (MANET) is a remote system that exchanges data from a source to a destination. This technology is now widely used all over the world since it does not require any fixed-wired system to establish communication between the source and the objective. The major threats to the mobile ad-hoc network include dark gap assaults and wormhole attacks. One of the most common attacks against mobile ad hoc networks (MANETs) is the gray hole attack, in which a hostile node promises to participate in route construction but then refuses to send data. The sensitivity of two popular ad hoc routing systems, Ad hoc On-Demand Distance Vector Routing (AODV) and Dynamic Source Routing (DSR) are investigated in this work. The Ad hoc On-demand Distance Vector (AODV) protocol is a common reactive routing technology that is vulnerable to the well-known packet dropping attack, in which a hostile node drops some packets without forwarding them to their intended destination. In this paper, the authors investigate how to protect packet dropping attacks in MANET using security measures such as data routing information (DRI) and cross-checking operations.
