We present a secure position-based protocol framework S-CORE, for ad-hoc networks. S-CORE consist of a secure hello protocol and a secure greedy forwarding protocol (SecFwd). The secure hello protocol helps nodes establish a neighbor table free of malicious nodes, defends against ID-spoofing, position-spoofing, and black lists malicious nodes. To detect position-spoofing, nodes use a new distributed position verification algorithm that uses a position- bounding technique. SecFwd mitigates forwarding misbehaviors and insures proper execution of greedy forwarding. We present a security analysis of S-CORE and results from an extensive simulation study using GloMoSim. Our simulation results show that S-CORE detects misbehaving nodes to a high degree with a fewer number of false accusations.
