Wireless Sensor Networks (WSNs) are exposed to a number of network attacks. Blackhole attacks are those in which an attacker takes control of the nodes and modifies the programming of a set of nodes such that packets are stopped rather being forwarded to the base station. In response to a route request message, a node acts as a gray hole node, selectively discarding and forwarding data after finding the shortest route to the destination node. The system sends packets to their destination via the AODV protocol. As a result, data entered in the attack area is intercepted and cannot reach its destination, resulting in reduced throughput and end-to-end delays. The system employs the IDS AODV technology to enhance performance, allowing us to effectively reduce assaults on integrated MANET-Internet connection.
