无线网状网(WMN)正逐渐成为未来的关键技术。WMN的自配置特性和可添加网状网路由器/网状点的简单性使其与确保其安全操作相关。无线网状网中的所有路由协议都天真地假设节点在转发彼此的分组时是合作的。然而，一个节点可能会表现出自私的行为，不连续地丢弃其他节点的数据包，试图最大化其吞吐量。在本文中，我们提出了一种用于促进节点协作的分布式方案，称为分布式自律架构(D-SAFNC)，用于加强WMN中节点之间的协作。我们使用一种分布式的方法来隔离任何自私的节点，并借助称为汇聚节点的局部检测代理。通过ns-2仿真验证了D-SAFNC算法能够有效地防止自私节点的存在导致网络性能下降。
Wireless Mesh Networks (WMNs) are evolving to be the key technology of the future. The self-configuring nature of WMNs and the ease, with which a mesh router/mesh point can be added, makes it pertinent to ensure their secure operation. All the routing protocols in WMNs naively assume the nodes to be co-operative in forwarding each other's packets. However, a node can behave selfishly by discretely dropping other's packets, in an attempt to maximize its throughput. In this paper, we present a distributed scheme called, Distributed Self-policing Architecture for Fostering Node Cooperation (D-SAFNC), for enforcing cooperation among the nodes in a WMN. We use a distributed approach in isolating any selfish node with the help of localized detection agents called sink nodes. We study the effectiveness of our scheme through simulations using ns-2 which reaffirm that D-SAFNC can successfully prevent any performance degradation due to the presence of selfish nodes.
