Routing of Misbehavior Nodes in Manets Using Acknowledgement Method
Bhagyashree Somnath Madan, R. Krishna · 2014
collection of mobile nodes (hosts) which communicate with each other via wireless links either directly or relying on other nodes as routers. The operation of MANETs does not depend on pre-existing infrastructure or base stations. Network nodes in MANETs are free to move randomly. The nodes which drop the information to send forward considered as a selfish Node. Specifically, nodes may participate in the route discovery and maintenance processes but refuse to forward data packets. To detect such misbehavior and more efficient detection process, the 2ACK technique is analyzed. The main idea of the 2ACK scheme is to send two-hop acknowledgment packets in the opposite direction of the routing path. The 2ACK scheme detects misbehavior through the use of a new type of acknowledgment packet, termed 2ACK. Thus it detects the misbehaving nodes, eliminate them and choose the other path for transmitting the data. The main aim of this application is to detect the routing misbehavior in Manets that occurs due to the presence of selfish node. The input to the system will be the number of nodes with data transmission between them. The output of the system will involve detecting the misbehaving link and misbehaving node due to which the packet loss occurs.
