Anonymous technology is an effective way for protecting users' privacy. Anonymity in sensor networks is to prevent the unauthorized third party from revealing the identities of the communication parties. While, in unstable wireless sensor networks, frequent topology changes often lead to route-failure in anonymous communication. To deal with the problems of anonymous route-failure in unstable sensor networks, in this paper we propose a fully anonymous routing protocol with self-healing capability in unstable sensor networks by constructing a new key agreement scheme and proposing an anonymous identity scheme. The proposed protocol maintains full anonymity of sensor nodes with the self-healing capability of anonymous routes. The results from the performance analysis show that the proposed self-healing anonymity-focused protocol achieves full anonymity of source nodes, destination nodes, and communication association.
匿名技术是保护用户隐私的有效方式。传感器网络中的匿名性旨在防止未经授权的第三方泄露通信各方的身份。然而，在不稳定的无线传感器网络中，频繁的拓扑变化常常导致匿名通信中的路由失败。为了解决不稳定传感器网络中匿名路由失败的问题，本文通过构建一种新的密钥协商方案并提出一种匿名身份方案，提出了一种在不稳定传感器网络中具有自愈能力的完全匿名路由协议。所提出的协议通过匿名路由的自愈能力保持传感器节点的完全匿名性。性能分析结果表明，所提出的以自愈匿名性为重点的协议实现了源节点、目的节点和通信关联的完全匿名性。
