    • A Robust Channel Estimation Scheme for 5G Massive MIMO Systems 

      Khan, Imran; Rodrigues, Joel J. P. C.; Al-Muhtadi, Jalal; Khattak, Muhammad Irfan; Khan, Yousaf; ... more authors ( Hindawi Limited , 2019 , Article)
      Channel state information (CSI) feedback in massive MIMO systems is too large due to large pilot overhead. It is due to the large channel matrix dimension which depends on the number of base station (BS) antennas and ...

    • DAGIoV: A Framework for Vehicle to Vehicle Communication Using Directed Acyclic Graph and Game Theory 

      Hassija, Vikas; Chamola, Vinay; Han, Guangjie; Rodrigues, Joel J.P.C.; Guizani, Mohsen ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)
      Data sharing and content offloading among vehicles is an imperative part of the Internet of Vehicles (IoV). A peer-to-peer connection among vehicles in a distributed manner is a highly promising solution for fast communication ...

    • Privacy and security issues in online social networks 

      Ali, Shaukat; Islam, Naveed; Rauf, Azhar; Din, Ikram U.; Guizani, Mohsen; ... more authors ( MDPI AG , 2018 , Article)
      The advent of online social networks (OSN) has transformed a common passive reader into a content contributor. It has allowed users to share information and exchange opinions, and also express themselves in online virtual ...

    • Secure and Lightweight Authentication Scheme for Smart Metering Infrastructure in Smart Grid 

      Garg, Sahil; Kaur, Kuljeet; Kaddoum, Georges; Rodrigues, Joel J.P.C.; Guizani, Mohsen ( IEEE Computer Society , 2020 , Article)
      In this article, a secure and lightweight authentication scheme, which provides trust, anonymity, and mutual authentication, with reduced energy, communicational, and computational overheads, is proposed for resource-constrained ...
