Abstract
Mobile ad hoc network is one of most important research topics as they are infrastructure-less and mobile. Open medium, wide distribution and de-centralization of nodes makes MANETs vulnerable and malicious. It is crucial to develop efficient intrusion detection system to protect MANETs. A new intrusion detection system named bandwidth shared acknowledgment (BSA) in which all transmission packet data and acknowledge should be cryptographically signed. Swarm Based Detection techniques for multiple paths establishment among source to destination and random casting is use during intrusion in MANETs. Eavesdropping in MANET is scheduled based on number of acknowledgement received at every instance in network. The theme of this paper is to provide a seamless message delivery in a MANET despite its threats using random casting and the existing mechanisms like 2-hop acknowledgement or source directed acknowledgement does not hold when a network topology changes frequently or when a node is compromised. These drawbacks are to be addressed ensuring secured connecting edges between source and destination. The source collision, exposure to vulnerability is also minimized using this mechanism. We propose an optimize solution for above problem using BSA techniques which overcomes eaves dropping based on acknowledgement from intermediate only and P2P content-based file sharing system, namely Intracommunity File Searching, for disconnected MANETs. The system uses an interest extraction algorithm to derive a node’s interests from its files for content- based file searching
