Fog-based MANET (Mobile Ad hoc networks) is a novel paradigm of a mobile ad hoc network with the advantages of both mobility and fog computing. Meanwhile, as traditional routing protocol, ad hoc on-demand distance vector (AODV) routing protocol has been applied widely in fog-based MANET. Currently, how to improve the transmission performance and enhance security are the two major aspects in AODV's research field. However, the researches on joint energy efficiency and security seem to be seldom considered. In this paper, we propose a source anonymity-based lightweight secure AODV (SAL-SAODV) routing protocol to meet the above requirements. In SAL-SAODV protocol, source anonymous and secure transmitting schemes are proposed and applied. The scheme involves the following three parts: the source anonymity algorithm is employed to achieve the source node, without being tracked and located; the improved secure scheme based on the polynomial of CRC-4 is applied to substitute the RSA digital signature of SAODV and guarantee the data integrity, in addition to reducing the computation and energy consumption; the random delayed transmitting scheme (RDTM) is implemented to separate the check code and transmitted data, and achieve tamper-proof results. The simulation results show that the comprehensive performance of the proposed SAL-SAODV is a trade-off of the transmission performance, energy efficiency, and security, and better than AODV and SAODV.
基于雾的移动自组织网络（MANET）是一种新型的移动自组织网络范式，兼具移动性和雾计算的优势。同时，作为传统路由协议，自组织按需距离矢量（AODV）路由协议已在基于雾的MANET中得到广泛应用。目前，如何提高传输性能和增强安全性是AODV研究领域的两个主要方面。然而，关于联合能效和安全性的研究似乎很少被考虑。在本文中，我们提出了一种基于源匿名的轻量级安全AODV（SAL-SAODV）路由协议来满足上述要求。在SAL-SAODV协议中，提出并应用了源匿名和安全传输方案。该方案包括以下三个部分：采用源匿名算法来实现源节点不被跟踪和定位；应用基于CRC-4多项式的改进安全方案来替代SAODV的RSA数字签名并保证数据完整性，同时降低计算量和能耗；实施随机延迟传输方案（RDTM）来分离校验码和传输数据，并实现防篡改效果。仿真结果表明，所提出的SAL-SAODV的综合性能是传输性能、能效和安全性的权衡，并且优于AODV和SAODV。
