Defense Against Selective Forwarding
{"Image DocumentName": "Defense Against Selective Forwarding", "Image ImageDescription": "Acknowledgements: Every intermediate node that forwards a packet waits for an acknowledgement from the next hope. If the next hope node does not return the same number of acknowledgements as the number of the packets sent, the node generates an alarm about the next hop node. Compromised nodes can generate acknowledgements also for the packets that they dropped which make this scheme fails. Moreover a malicious node can generate fake alarms to organize a DoS attack. Multipath routing: This requires at least link disjoint paths, where two paths may share some nodes but any link. Of course node disjoint paths, where two paths do not have any node in common, are better and reduce the risk of selective forwarding attack.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
