不可信环境下的路由性能问题,是移动自组织网(mobile ad-hoc networks,MANET)匿名路由协议面临的主要问题之一.本文为在不可信环境下通过对自私节点进行高效的协作激励,提高匿名路由协议的性能,提出了一种基于哈希链的匿名位置辅助路由激励机制.该机制利用哈希链在计算上的高效性和安全上的不可逆性,达成了对匿名数据转发节点的即时激励；通过基于支付代价的路由选择机制,优化了现有位置辅助路由机制的路由发现过程.匿名性分析证明,该机制能保证参与路由节点的匿名性.效率评价表明,在数据传输总量较大时,该机制对路由性能的影响很小,且该机制在较小规模的网络中有更好的性能.%The routing performance issues in untrusted environments are the serious challenges for the privacy protection routing protocols in mobile ad-hoc networks (MANET). In order to encourage the selfish nodes and improve the routing performance in untrusted environments, this paper proposes an anonymous incentive mechanism based on hash-chain for the location-aided routing protocols. By using the efficiency and irreversibleness of hash-chain to the location-aided routing protocols, this mechanism can realize immediate incentive to the anonymous forwarders.Moreover, this mechanism can optimize the routing discover process through a route selection mechanism based on the payment price. The anonymity analyses indicate this mechanism can guarantee the anonymities of the nodes involved in routing.The performance evaluation shows that this mechanism has little effect on the routing performance when large amounts of data are transferred,and it is more efficient in small scale networks.
