Guaranteed Delivery Flooding Protocols for Mobile Ad Hoc Networks* Ioannis (Yannis) Avramopoulos Department of Electrical Engineering Princeton University Abstract: Flooding is an important tool in the routing operations of wireless ad hoc networks with applications to both topology/route discovery and data packet forwarding. I will present two "guaranteed delivery" flooding protocols. The protocols "guarantee" successful delivery of packets from a source router to any non-faulty router in a network that is connected by at least one non-faulty path to the source router, even if the behavior of faulty routers and links is arbitrary and malicious. The first protocol is based on digital signatures. It improves earlier work by preventing the adversary from overwhelming a victim router with spurious digital signatures. The second protocol is based on the TESLA broadcast authentication protocol. * Joint work with Hisashi Kobayashi
