摘要：Mobile Ad Hoc Networks (MANET) has been highly vulnerable to attacks due to the dynamic nature of its networkinfrastructure. Among these attacks, the routing attacks getting more attention because it’s changing the whole topology itself and it causesmore damages to MANET. The existing algorithm not provides the anonymity protection and finding the malicious node with degree ofevidence from the expert knowledge and detects the important factors for each node. In proposed method the ALERT protocol is developedfor overcome the existing problem. ALERT protocol is mainly providing a high anonymity protection with low cost. Using proposed protocolthe network fields are dynamically partitions into zones and zones are randomly chosen from the nodes as intermediate relay nodes, whichform a non-traceable by anonymous route. Particularly in every routing step, a data sender or forwarder division the network field in orderto disconnected itself and the destination into two zones. In the last step, the data are broadcast to k nodes in the destination zone providingk-anonymity to the destination. ALERT is also flexible to timing attacks and intersection attacks. In addition, the experiments demonstratethe effectiveness of proposed approach with the consideration of several performance metrics
