Secure Data Transmission to Improve the Performance of Communication in Hybrid Systems

Abstract

Light Fidelity (Li-Fi) is a way of communication using LED’s with a high data rate and secures data transmission. But it has some drawbacks like data loss during shadowing and flickering of light, interference, etc. To deal with data loss we can use Hybrid Li-Fi and Wi-Fi  Networks (HLWNets) by combining Li-Fi and Wireless Fidelity (Wi-Fi). Emerging HLWNets design and implementation face secure data transmission issues introduced due to Wi-Fi networks. We propose a novel comprehensive solution called Efficient Handover Protocol with Secure Data Transmission (EHPSDT).To assure the total security of data, we proposed security architecture based on Attributed-based Elliptic Curve Encryption (AECC) that ensures confidentiality and integrity. It also allows for fine-grained access control in HLWNets. Compared to other current methodologies, the proposed method minimizes overall processing overhead. The result of simulation revealed the performance of the proposed EHPSDT compared to underlying methods in terms of packet delivery ratio (PDR), average throughput, and communication overhead.
