无线Mesh网络中基于跨层信誉机制的安全路由协议

Cross layer reputation mechanism based secure routing protocol for WMNs

无线Mesh网络特殊的网络结构和通信模式,使其容易遭受各种安全威胁.其中,针对路由安全和用户隐私安全的内部攻击是最具有挑战的问题之一.针对上述问题,首先提出了一种新的跨层信誉机制.然后,基于跨层动态信誉机制提出了一种能够实现隐私保护的安全路由协议CR-HWMP.仿真结果表明,CRHWMP能够有效抵御黑洞和灰洞等内部攻击,实现用户信息的隐私保护,提高网络的可靠性和安全性.

Wireless mesh networks are faced with various security threats due to their special infrastructure and communication mode, where the internal attacks aiming at routing security and user privacy security are one of the most challenging issues. In this paper a novel cross layer reputation mechanism is first proposed to identify and isolate the internal malicious nodes. Then, a privacy-aware secure routing protocol CR- HWMP based on the proposed reputation mechanism is proposed. Performance analysis and simulation results show that CR-HWMP can effectively implement the privacy preserving and defend against the internal attacks such as black hole and gray hole, and improve the reliability, robustness and security of the wireless mesh networks efficiently.
