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.
Abstract translation: 提供了使用Ad Hoc网络中的可靠性评分系统的路由攻击排除方法，以使用路由错误信号和索赔检查信号来识别错误的节点，并且稍后在路径分配中排除错误节点，从而配置稳定的Ad Hoc网络系统 。 用于Ad Hoc网络系统的节点（100）包括数据生成/中继单元（110），接收检查单元（120），索赔报告单元（130），索赔检查/验证单元（140）和可靠性 值处理单元（150）。 数据生成/中继单元生成或中继和发送数据。 当从不同节点发送的数据作为最终目的地接收时，接收检查单元产生接收检查信号，并且以相反的方向发送接收检查信号。 当在作为中继节点的操作期间没有从最终目的地的目标节点接收到接收检查信号时，权利要求报告单元向源节点发送RERR（路由错误）信号，并向源节点报告权利要求。 权利要求检查/验证单元向最接近目标节点的中继节点发送权利要求检查信号，其中接收权利要求检查信号的先前良好节点向所述目标节点发送权利要求验证信号。 当接收到权利要求检查信号时，可靠性值处理单元将下一路径的节点识别为错误节点，并且稍后在路径分配中排除节点。
