现有的合作通信协议的设计假设，用户总是表现在一个社会有效的方式。这个假设在单一权威控制下的网络中可能是有效的，其中节点有效地合作以实现共同的目标。另一方面，在商业无线网络中，节点被单独激励合作，假设节点将始终遵守合作规则可能不成立，而不实施一种机制来检测和减轻不当行为。本文提出了一种基于序贯概率比测试（SPRT）的自动重传请求（ARQ）协作网络中的序贯错误行为检测方法。我们评估性能的检测技术分析和使用数值方法。
Existing cooperative communications protocols are designed with the assumption that users always behave in a socially efficient manner. This assumption may be valid in networks under the control of a single authority where nodes cooperate efficiently to achieve a common goal. On the other hand, in commercial wireless networks where nodes are individually motivated to cooperate, the assumption that nodes will always obey rules of cooperation may not hold without implementing a mechanism to detect and mitigate misbehavior. In this paper, we present a sequential misbehavior technique based on Sequential Probability Ratio Test (SPRT) for cooperative networks using automatic repeat request (ARQ). We evaluate performance of the detection technique both analytically and using numerical methods.
