移动自组织网络（manet）由于其独特的特性，如高度动态的网络拓扑结构、严格的功率限制和容易出错的传输介质，容易受到各种节点错误行为的影响。已经做出了重大的研究努力来解决不良行为检测的问题。然而，对于区分真正的恶意行为和错误行为的研究工作却很少。大多数传统的不当行为检测机制通常将恶意行为和错误行为等同视为不当行为，而不作进一步的研究。在本文中，我们提出并开发了一种基于策略的恶意对等体检测机制，该机制收集通信通道状态、缓冲状态和传输功率水平等上下文信息，然后用于确定错误行为是否可能是恶意活动的结果。仿真结果表明，基于策略的恶意对等体检测机制能够以较高的置信度区分恶意对等体和故障对等体。此外，该机制以有限的通信开销收敛于所有节点之间的恶意节点的一致视图。
Mobile Ad hoc Networks (MANETs) are susceptible to various node misbehaviors due to their unique features, such as highly dynamic network topology, rigorous power constraints and error-prone transmission media. Significant research efforts have been made to address the problem of misbehavior detection. However, little research work has been done to distinguish truly malicious behaviors from the faulty behaviors. Both the malicious behaviors and the faulty behaviors are generally equally treated as misbehaviors without any further investigation by most of the traditional misbehavior detection mechanisms. In this paper, we propose and develop a policy-based malicious peer detection mechanism, in which context information, such as communication channel status, buffer status, and transmission power level, is collected and then used to determine whether the misbehavior is likely a result of malicious activity or not. Simulation results il-lustrate that the policy-based malicious peer detection mechanism is able to distinguish malicious peers from faulty peers with high confidence. Moreover, the mechanism converges to a consistent view of malicious nodes amongst all the nodes with a limited communication overhead.
