    A Secure Routing Protocol for MWNs Based on Cross-Layer Dynamic Reputation Mechanism

    • 摘要: 无线多跳网络(multi-hop wireless networks, MWNs)面临着各种攻击的威胁,尤其是针对路由安全的内部多层攻击和诽谤攻击.信誉机制作为评估节点间信任关系和抵御内部攻击的有效方法,已经被引入MWNs用于保护路由安全.然而,现有成果主要采用分层设计,只考虑单一层次上的攻击,忽略了多层攻击;同时,现有成果还忽略了诽谤攻击和推荐节点的可信性,降低了信誉度评估结果的可靠性.针对上述问题,首先提出基于可靠推荐的跨层动态信誉机制(cross-layer dynamic reputation mechanism, CRM).然后,基于CRM提出了基于推荐保护和跨层信誉机制的安全路由协议(recommendation protection and cross-layer reputation mechanism based secure routing protocol, RPCSR).仿真结果和性能分析表明,RPCSR能够有效抵御内部多层攻击及诽谤攻击,保障路由安全.

       

      Abstract: Multi-hop wireless networks (MWNs) face various attacks threats, especially the internal multi-layer attacks and bad mouthing attack aiming to the routing security. As an effective method to evaluate the trust relationship between the nodes and against internal attacks, reputation mechanisms have been introduced into MWNs to preserve the routing security. Although there are a multitude of research work, most of them are based on the layered design and only considering the single layer attacks, thus ignoring the multi-layer attacks. And they also ignore the bad mouthing attack and the creditability of the recommended nodes and recommended information, which reduces the reliability of the reputation evaluation results. To solve the above problem, this paper first proposes a new reliable recommendation based cross layer dynamic reputation mechanism named CRM, and then proposes a secure routing protocol RPCSR based on the CRM. Simulation results and performance analysis demonstrate that the proposed secure routing protocol RPCSR can implement routing security preserving against the internal multi-layer attacks and bad mouthing attack effectively.
