Abstract
The exponential rise in wireless transmission has gained widespread attention to meet major mobile communication purposes including, Internet of Things (IoT) and Machine-to-Machine (M2M) communications. Mobile Ad-hoc Network (MANET) has emerged as one of the most viable solution to meet aforesaid mobile communication purposes; however, being decentralized and infrastructure-less network it undergoes adversaries including dynamic topology and security breaches due to malicious node attachment during routing. On the contrary, data security and allied Quality-of-Service (QoS) provision are inevitable in NextGen communication systems. Unlike routing-based security measures, Medium Access Control (MAC) based approaches are found more effective for MANETs. However, most of the classical MAC designs either address QoS or security as standalone objective. Unlike existing MAC solutions, in this paper a state-of-art novel Huffman Coding and Multi-Generation Mixing (MGM) assisted random linear network model-based MAC design (HM2-MAC) is proposed for MANET. Realizing the robustness of the network coding algorithms towards reliable, secure and error-free multicast transmission, we designed HM2-MAC in such manner that Huffman coding helps securing the source data packets, while MGM concept enables reduction in redundant packets to make overall communication resource efficient and secure. Unlike redundant packet-per-generation, MGM concept helps in reducing redundant transmission and hence achieves resource efficiency. Since, in HM2-MAC model the coefficient matrix used to encode the data is known only to the sink, no intermediate node can decode it or can pollute it. It makes multicast transmission more secure over MANET. Additionally, the use of iterative buffer flush technique preserves resources or buffer to accommodate more data for transmission and hence higher throughput. Noticeably, error sensitive packetization and MGM control strengthens our proposed model to retain optimal performance. HM2-MAC has been applied as a sub-layer of native IEEE 802.11 MAC and hence retains backward compatibility towards real-world implementation. MATLAB based simulation revealed that our proposed HM2-MAC protocol achieved almost 99.6% throughput even under varying link-loss patterns, which reveals its robustness to ensure QoS delivery with secure data transmission in MANET.
Highlights
In the last few years wireless communication has gained significant demands to meet major communication purposes serving healthcare sector, defense sector, industrial monitoring and control, civic as well as strategic monitoring and surveillance, business communication etc
Aforesaid network characteristics broadens the horizon for intruders or malicious node to become a part of routing table or forwarding path
Unlike routingbased approaches Medium Access Control (MAC) based systems have higher potential to meet both data security as well as QoS support; there are very less efforts made to explore MAC efficiency towards QoS and data security together. Considering these facts, in this paper we focused on designing a state-of-art new MAC routing protocol or architecture which could retain both QoS as well as data security, especially for Mobile Ad-hoc Network (MANET), a mobility based wireless routing technology
Summary
In the last few years wireless communication has gained significant demands to meet major communication purposes serving healthcare sector, defense sector, industrial monitoring and control, civic as well as strategic monitoring and surveillance, business communication etc. Homomorphic encryption-based network coding and MAC designed [40][43] can prohibit pollution attack up to certain extent, the computational overheads imposed and compromised throughput performance can’t be denied It can affect overall QoS provision by MANET. A compression-based encryption at one hand improves data security from any possible pollution attack or intermediate attack, while MGM with iterative buffer flush enables resource efficient and error-resilient multicast transmission over MANETs. The proposed HM2-MAC has been designed to cope up with multicast transmission and error-sensitive MGM generation, which makes it robust to achieve resource efficiency even with low Galois Field (GF) size and (low) number of redundant packets.
