Performance analysis of proposed mobile autonomous agent for detection of malicious node and protecting against attacks in MANET

Routing in mobile ad hoc network (MANETs) for groups should aim at providing reliable and robust multicast routes to the group members against link and node failures with mobility conditions. This paper propose an agent-based multicast routing scheme like On-Demand Multicast Routing Protocol (ODMRP) which can be more suitable for Ad Hoc network but D-ODMRP Destination driven On-Demand Multicast Routing Protocol is used to reduce the number of nodes to be added in the forwarding group. D-ODMRP introduces the features into the existing on demand process of multicast forwarding structure in MANET that builds a backbone in the form of a reliable mesh and finds multicast routes. Mobile autonomous agent technique for intrusion detection system in MANET has been proposed where agents are fired from a source node which traverses each node randomly and detect the malicious node. The link failure are detected and repaired by nearby nodes. This paper illustrate three types of performance analysis they are packet delivery ratio against number of multicast group, power consumption of nodes verses number of nodes & network area verses no of nodes and found that proposed system is better.
