- W2898146539 abstract "With an unprecedented amount of sensitive data and private information generated by mobile devices, security becomes critical for the emerging ultradense network. The conventional approach of encryption is not suitable to provide desired level of security as a result of increased scalability. Thus, physical layer protection is stressed to ensure secure transmission to users in dense environment. In this paper, we examine the security challenges of high speed users for ultradense network under dense picocells deployment. Initially, we consider a dense condition where users are randomly distributed within the picocell. Targeting the problem of security for vehicular users, we propose a beam broadening (BB) and beam merging (BM) techniques that ensure reliable transmission between source and destination. We prove the effectiveness of proposed approach through mathematical and simulation analysis that guarantees high QoS and secure communication. Based on the above formulations, we examine the reliability and potential capability of BB and BM with the measurement of fairness security assessment (FSA). Numerical results demonstrate that BM and BB can achieve higher value of secrecy rate and FSA, in comparison to conventional beamforming. To end this, the complexity analysis is performed in terms of beam generations as a function of speed of user." @default.
