    The Internet of Medical Things (IoMT) is structured upon both the sensing and communication infrastructure and computation facilities. The IoMT provides the convenient and cheapest ways for healthcare by aiding the remote access to the patients’ physiological data and using machine learning techniques for help in diagnosis. The communication delays in IoMT can be very harmful to healthcare. Device to device (D2D) secure communication is a vital area that can reduce communication delays; otherwise, caused due to the mediation of a third party. To substantiate a secure D2D communication framework, some schemes were recently proposed to secure D2D based communication infrastructure suitable for IoMT-based environments. However, the insecurities of some schemes against device physical capture attack and non-provision of anonymity along with related attacks are evident from the literature. This calls for a D2D secure access control system for realizing sustainable smart healthcare. In this article, using elliptic curve cryptography, a certificate based D2D access control scheme for IoMT systems (D2DAC-IoMT) is proposed. The security of the proposed D2DAC-IoMT is substantiated through formal and informal methods. Moreover, the performance analysis affirms that the proposed scheme provides a good trade-off between security and efficiency compared with some recent schemes.

    A Physical Capture Resistant Authentication Scheme for the Internet of Drones
    (Institute of Electrical and Electronics Engineers Inc., 2021) Chaudhry, Shehzad Ashraf; Nebhen, Jamel; Irshad, Azeem; Bashir, Ali Kashif; Kharel, Rupak; Yu, Keping; Zikria, Yousaf Bin
    The internet of Drones (IoD) can encompass many essential services, including surveillance and emergency/rescue operations. While IoD is becomin popular and experiencing a rapid usage increase, privacy and security are the main concerns to avoid leakage of critical information and/or denial of services by a single drone or a whole IoD network. In addition to traditional privacy cum security issues, the physical capture of a single drone can severely impact the entire IoD network. This article provides an overview of the security challenges and requirements for IoD environments in addition to a discussion related to IoD communication/security standards. More-over, this article proposes a novel scheme for securing IoD specifically, from physical drone capturing and related attacks. © 2017 IEEE.

    Toward Optimal Cost-Energy Management Green Framework for Sustainable Future Wireless Networks
    (TECH SCIENCE PRESS, 871 CORONADO CENTER DR, SUTE 200, HENDERSON, NV 89052, 2021) Alsharif, Mohammed H.; Jahid, Abu; Albreem, Mahmoud A. M.; Uthansakul, Peerapong; Nebhen, Jamel; Yahya, Khalid O. Moh.
    The design of green cellular networking according to the traffic arrivals has the capability to reduce the overall energy consumption to a cluster in a cost-effective way. The cell zooming approach has appealed much attention that adaptively offloads the BS load demands adjusting the transmit power based on the traffic intensity and green energy availability. Besides, the researchers are focused on implementing renewable energy resources, which are considered the most attractive practices in designing energy-efficient wireless networks over the long term in a cost-efficient way in the existing infrastructure. The utilization of available solar can be adapted to acquire cost-effective and reliable power supply to the BSs, especially that sunlight is free, available everywhere, and a good alternative energy option for the remote areas. Nevertheless, planning a photovoltaic scheme necessitates viability assessment to avoid poor power supply, particularly for BSs. Therefore, cellular operators need to consider both technical and economic factors before the implementation of solar-powered BSs. This paper proposed the user-centric cell zooming policy of solar-powered cellular base stations taking into account the optimal technical criteria obtained by the HOMER software tool. The results have shown that the proposed system can provide operational expenditure (OPEX) savings of up to 47%. In addition, the efficient allocation of resource blocks (RBs) under the cell zooming technique attain remarkable energy-saving performance yielding up to 27%.
