开放式移动的社交网络(OMSN)使用户能够形成用于信息共享的即时社交网络(例如,观看同一场足球比赛的人可以分享他们的即时评论)。OMSN本质上是特设的,因此依赖于成员之间关于消息传输的合作。然而,一些不正常成员的不合作或恶意行为可能会降低网络性能,甚至破坏整个网络。目前,还没有有效的机制来检测自私和恶意节点。为了解决这个问题,我们提出了一个动态的信任框架,以方便一个节点来获得另一个节点的信任值的基础上,后者的行为。我们的框架的新奇包括以下内容:1)我们设计了一个新的度量的信任值的节点和2)我们提出了一个“两跳反馈方法”,需要在转发路径中的中间节点生成ACK消息,以验证节点的诚实,如果他们是两个跳。在大多数现有的信任模型中,最终ACK消息被认为是关键因素。在OMSN中,节点没有完全连接,最终的ACK消息不能被可靠地接收。为了避免最终ACK消息很少能被接收到的问题,我们提出了一种“两跳反馈方法”。仿真结果表明,我们的方法能够检测到大多数异常节点,包括恶意节点,自私节点,和那些发动阴谋攻击的节点。因此,可以提高整个网络的效率,而不会受到异常节点的负面影响。此外,我们的信任框架可以很容易地应用到当前流行的机会网络路由协议。
Opportunistic mobile social network (OMSN) enables users to form an instant social network for information sharing (e.g., people watching the same soccer game can share their instant comments). OMSN is ad hoc in nature, thus relies on the cooperation of members regarding message transmission. However, some uncooperative or malicious behavior from abnormal members may reduce network performance, even damage the entire network. Currently, there does not exist effective mechanisms to detect selfish and malicious nodes. To tackle this problem, we propose a dynamic trust framework to facilitate a node to derive a trust value of another node based on the behavior of the latter. The novelty of our framework includes the following: 1) we design a new metric for a trust value of a node and 2) we propose a “two–hop feedback method” that requires intermediate nodes in a forwarding path to generate ACK messages to verify a node’s honesty if they are two hops away. In most existing trust models, final ACK messages are considered as critical factors. In OMSN, nodes are not fully connected and final ACK messages cannot be reliably received. In order to avoid the problem that few final ACK messages can be received, we propose a “two–hop feedback method.” Simulation results show that our approach is able to detect a majority of abnormal nodes including malicious nodes, selfish nodes, and those nodes launching conspiracy attacks. Thus, the entire network efficiency can be improved without negative impact of abnormal nodes. Besides, our trust framework can be easily applied to the current popular routing protocols of opportunistic networks.
