Abstract: A routing attack exclusion method using a reliability scoring system in an Ad Hoc network is provided to recognize a wrong node using a routing error signal and a claim check signal and exclude the wrong node in path assignment later, thereby configuring a stable Ad Hoc network system. A node(100) for an Ad Hoc network system comprises a data generation/relay unit(110), a reception checking unit(120), a claim reporting unit(130), a claim check/verification unit(140) and a reliability value processing unit(150). The data generation/relay unit generates, or relays and transmits data. The reception checking unit generates reception check signal when data transmitted from a different node is received as a final destination and transmits the reception check signal in a reverse direction. The claim reporting unit transmits an RERR(Routing Error) signal to a source node when the reception check signal is not received from a target node of a final destination during operation as a relay node, and reports a claim to the source node. The claim check/verification unit transmits a claim check signal to a relay node nearest to the target node, wherein a previous good node receiving the claim check signal transmits a claim verification signal to the target node. The reliability value processing unit recognizes a node of a next path as a wrong node when the claim check signal is received and excludes the node in path assignment later.
