please every body show me code based on..
The logic behind detecting malicious nodes is as follows:
1. The source node sends a fake RREQ (Route Request) into the network.
2. As soon as a blackhole node receives it, it generates a fake RREP (Route Reply), falsely claiming to have the shortest path back to the source.
3. The source node waits for responses from the network. If it receives an immediate reply, that node is flagged as a blackhole.
4. The source node then broadcasts an alert to other nodes, warning them about the malicious node, add to suspended list.
5. Once the blackhole node is suspended, the system becomes secure against further attacks during real RREQ transmissions and other processes
