“…For the reason that Nakagamim distribution is equal to Rayleigh distribution, Rician distribution and unilateral Gaussian distribution respectively when it chooses different shape parameter, which can better fit with the actual channel fading. Therefore, it is more practical to study other performance metrics such as achievable secrecy rate, optimal power allocation, secrecy throughout under Nakagami-m fading channels [22], [36], [39]. The numerical results show as follows: Firstly, the SRT of the BRS scheme always performs better than that of ERS scheme.…”

In this paper, we investigate an energy-harvesting cooperative communication network, which comprises of a source, a destination, and multiple decode-and-forward (DF) relays in the presence of multiple passive eavesdropper (Es). Es attempt to intercept confidential information transmissions from the source to destination via DF relays. In this network, all the DF relays harvest energy from radio-frequency (RF) signals of a source through time-switching receivers. In order to improve the physical layer security of energyharvesting cooperative communication networks, we propose a best relay selection (BRS) scheme, where the ''best'' relay is chosen to assist the source-destination transmission. For the purpose of comparison, we consider the classic direct transmission (DT) and equal relay selection (ERS) as benchmark schemes. We derive the exact closed-form expressions of outage probability (OP) and intercept probability (IP) for the ERS and BRS schemes over Rayleigh fading channels. Besides, the security-reliability tradeoff (SRT) is analyzed as a metric to evaluate the tradeoff performance of the proposed BRS scheme. Numerical results show that the SRT of the BRS scheme consistently outperforms that of the ERS scheme, which demonstrates the advantage of our proposed scheme against eavesdroppers. Besides, it is verified that total error rate (TER) defined as the sum of OP and IP can be minimized for both the ERS and BRS schemes through changing the time allocation factor between information transmission and energy harvesting phases. Moreover, there is a best energy conversation efficiency to obtain a maximal SRT value of the ERS and BRS schemes. In addition, as the number of DF relays increases, the SRT of BRS scheme improves notably, while that of ERS scheme remains unchanged. And as the number of Es increases, the SRT of both the ERS and BRS schemes become worse. INDEX TERMS Cooperative communication, physical layer security, best relay selection (BRS), outage probability (OP), intercept probability (IP), security-reliability tradeoff (SRT).

“…Recently, cooperation communication is exploited as an effective way to guarantee physical layer security of wireless communication [22]- [24]. In cooperative communication networks, relays act as intermediate wireless devices and adopt amplify-and-forward (AF) and decode-and-forward (DF) protocols to process received signals.…”

“…Although some scholars have proposed a distributed access control method to confidential information, it brings too much delay and overhead. IPSec and TLS are used in reference [32] to provide authentication and privacy, but they are not suitable for various computing devices with limited resources due to the large computing cost. Their consensus mechanism and block validation are contrary to the requirements of complex blockchain solutions.…”

With the rapid development of industrial internet of thing (IIoT), the distributed topology of IIoT and resource constraints of edge computing conduct new challenges to traditional data storage, transmission, and security protection. A distributed trust and allocated ledger of blockchain technology are suitable for the distributed IIoT, which also becomes an effective method for edge computing applications. This paper proposes a resource constrained Layered Lightweight Blockchain Framework (LLBF) and implementation mechanism. The framework consists of a resource constrained layer (RCL) and a resource extended layer (REL) blockchain used in IIoT. We redesign the block structure and size to suit to IIoT edge computing devices. A lightweight consensus algorithm and a dynamic trust right algorithm is developed to improve the throughput of blockchain and reduce the number of transactions validated in new blocks respectively. Through a high throughput management to guarantee the transaction load balance of blockchain. Finally, we conducted kinds of blockchain simulation and performance experiments, the outcome indicated that the method have a good performance in IIoT edge application.
