Denial-of-service attack (BH and PDA) effect analysis on AODV Routing Protocol with Random Mobility
Main Article Content
Abstract
Mobile ad hoc networks (MANETs) has received significant attention in the research domain of routing protocol as they provide security to transmit the data at the destination node. Mobile ad hoc networks do not have a fixed infrastructure, and nodes have random mobility due to this network topology changing dynamically and it vulnerable to external threats. Block hole and packet dropping are well-known network layer Denial of service attacks. during the route, discovery phase malicious nodes work normally and it became the shortest path to route the data and after that, it will drop all the data instead of transferring the data to the destination and in case of the packet dropping attack node drop the packet due to the elfishness of a node, Lack of energy resources, Bandwidth consumed by the attacker node, Overflow of the transmission queue, Misbehavior of a malicious node, it will drop the packet in the network. In this paper, we analyze the impact of both attacks on the AODV routing protocol in the random mobility environments with the different simulation parameters.
