Abstract
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.
Highlights
Every application and system that is managed in a cloud and mobile cloud service is promising for big data processing
In QAODV, two additional fields were added to the message of ad hoc on-demand distance vector (AODV) routing protocol in order to improve the performance in terms of Packet Delivery Ratio (PDR), Packet Loss Rate (PLR), and average E2ED
The reverse path will be maintained for a certain time in the routing table, so that the route reply (RREP) message can return to the source node along it
Summary
Every application and system that is managed in a cloud and mobile cloud service is promising for big data processing. Centralized cloud computing is unnecessary and inefficient for the management and application in a large-scale mobile ad hoc network. Fog computing was firstly proposed by Cisco in 2012 [1]. It is an extension of the cloud-based Internet. It is introduced as an intermediate layer between mobile devices and the cloud in order to provide smooth, low-latency service delivery from the cloud to the mobile.
