Geographical Secure Path Routing for Mobile Ad-hoc Networks
Vivek Pathak

We present geographical secure path routing, an infrastructure free
geographic routing protocol that is resilient to
disruptions from malicious or faulty nodes.  Our protocol authenticates
the geographical location of anonymous nodes to secure routing
and to provide location authentication and privacy simultaneously.

We study the overhead required for location authentication
by comparing with greedy perimeter stateless routing as the baseline.
The overhead of the protocol is also studied
under attack scenarios. Our protocol also authenticates the routing paths taken
by individual messages.  This provides a basis for geographical
security policies. .
