Journal ArticleDOI
Security and Privacy in Wireless IoT
TL;DR: The 13 articles in this special section focus on security and privacy in wireless Internet of Things (IoT), a paradigm that involves networked physical objects with embedded technologies to collect, communicate, sense, and interact with the external environment through wireless or wired connections.
Proceedings ArticleDOI
Resource Allocation for Edge Computing-Based Blockchain: A Game Theoretic Approach
TL;DR: The aim is to find the optimal incentive for the ESP and miners to choose auto-fit strategies under two different mining schemes, and demonstrates the effectiveness of the proposed scheme on encouraging devices to participate the Blockchain.
Proceedings ArticleDOI
A Hybrid NOMA-PLNC Wireless Relay Scheme
TL;DR: In this paper, the outage performance of a two-pair hybrid NOMA-PLNC relay network is analyzed and a closed form expression for the end-to-end outage probability is derived.
Proceedings ArticleDOI
Radio resource allocation for cooperative relay-assisted OFDMA wireless networks
Zheng Chang,Tapani Ristaniemi +1 more
TL;DR: This paper considers a wireless cooperative OFDMA network with a base station and some relays and confirms that the proposed algorithm can enhance the performance compared with newly proposed resource allocation schemes.
Journal ArticleDOI
Pay-As-You-Go: A Wireless Power Transfer-Enabled Beamforming for Cooperative Communication Systems
Selvakumar Tharranetharan,Dushantha Nalin K. Jayakody,P. Muthuchidambaranathan,Zheng Chang,Moises V. Ribeiro +4 more
TL;DR: To administrate EUs WPT and ensure the fair service policy, this proposes a novel beamforming technique named Pay-As-You-Go beamforming, which adapts data rates proportional to the amount of energy received from each EUs while optimizing the energy per bit cost of the overall system.
