چکیده
In this paper, we investigate the trust-degree-based secure relay selection in simultaneous wireless information and power transfer (SWIPT)-enabled networks. particular, optimize interference by selecting appropriate time division ratio on condition of both transmission trust degree. First, applying security capacity constraint, derive expressions concerning Then, discuss different results for degrees determine set to guarantee communications. Finally, according degrees, compute needed each make a obtain optimal performance under Simulation show that with known degree proposed algorithm obtains ratio, reduces energy consumption, guarantees an achievable rate.

Joint Resource Optimization for Cognitive Sensor Networks with SWIPT-Enabled Relay
Energy-constrained wireless networks, such as wireless sensor networks (WSNs), are usually powered by fixed energy supplies (e.g., batteries), which limits the operation time of networks. Simultaneous wireless information and power transfer (SWIPT) is a promising technique to prolong the lifetime of energy-constrained wireless networks. This paper investigates the performance of an underlay cog...
متن کاملSecure Communications for Two-Way Relay Networks Via Relay Chatting
In this paper, we investigate a two-way relay network consisting of two sources, multiple cooperative relays and an eavesdropper. To enhance secure communications, a new relay chatting based on transmission scheme is proposed. Specifically, the proposed scheme selects a best relay that maximize the sum mutual information among the sources to forward the sources’ signals using an amplify-and-for...
متن کاملRelay Selection for Af Based Cooperative Networks
In this paper, a performance analysis of amplifyand-forward (AF) relaying cooperative diversity system with relay selection is given when all terminals are moving. We have derived analytical expressions for probability density function (PDF), cumulative distribution function (CDF) and moment generating function (MGF) of end-to-end signal-to-noise ratio (SNR) for the considered system. Then, the...
متن کاملUnified Analysis of SWIPT Relay Networks with Noncoherent Modulation
Simultaneous wireless information and power transfer (SWIPT) relay networks represent a paradigm shift in the development of wireless networks, enabling simultaneous radio frequency (RF) energy harvesting (EH) and information processing. Different from conventional SWIPT relaying schemes, which typically assume the availability of perfect channel state information (CSI), here we consider the ap...
متن کاملQBCO and NSQBCO Based Multi-User Single-Relay Selection Scheme in Cooperative Relay Networks
In cooperative relay networks with multiple users and multiple potential relays, which relay nodes are selected has great impact on the system performance. It is an optimization problem for selecting suitable relay nodes. The exhaustive search can solve this problem but the complexity will increase factorially with the network size, i.e., the number of users and the number of relays in the netw...
