“…The joint relay and antenna selection can also consider the selection of antenna as per the channel conditions and relay selection as per the SINR (Yang et al, 2015). Yu et al (2020) minimises the energy consumption of the system by enabling sleep mode at the BS which activates only few RF chains at a time. Demirkol and Kucur (2020) and Huang et al (2018) compares different antenna selection schemes to evaluate the outage performance of the energy harvesting relay cooperative network.…”

In this paper, a 5G mobile communication system is considered with cooperative environment. The mobile and base-station node communicate with each other through a number of amplify-and-forward (AF) relays. The users have multiple antennas while each relay has a single antenna. The radio-frequency (RF) transceiver chain associated with each antenna element leads to increased hardware complexity. This challenge is reduced by efficient utilisation of RF front ends in the proposed wireless system. The paper proposes an RF chain selection technique which enables the selection of RF front end with maximum received signal-to-noise-ratio (SNR). The outage probability is derived for proposed mobile communication system. Further, system ergodic capacity, energy efficiency and average end-to-end SNR are evaluated. As compared to the conventional random selection approach, this algorithm aims to achieve higher capacity and higher average end-to-end-SNR. At 16 dB SNR, system capacity improves by 52% with proposed algorithm rather than conventional random selection.

“…In [ 7 ], the two–channel model

with WV, negative customers, feedback, and N-strategy was proposed to reduce the energy consumption in wireless communication networks. The energy saving capabilities of WV models were also discussed from the cloud platform point of view, see, e.g., [ 8 , 9 ].…”

A single server GI/M/1 queue with a limited buffer and an energy-saving mechanism based on a single working vacation policy is analyzed. The general independent input stream and exponential service times are considered. When the queue is empty after a service completion epoch, the server lowers the service speed for a random amount of time following an exponential distribution. Packets that arrive while the buffer is saturated are rejected. The analysis is focused on the duration of the time period with no packet losses. A system of equations for the transient time to the first buffer overflow cumulative distribution functions conditioned by the initial state and working mode of the service unit is stated using the idea of an embedded Markov chain and the continuous version of the law of total probability. The explicit representation for the Laplace transform of considered characteristics is found using a linear algebra-based approach. The results are illustrated using numerical examples, and the impact of the key parameters of the model is investigated.

“…Nowadays, queueing theory studies are also increasingly applied to the P2P network system.Ferragut and Paganini [9] analyzed the dynamic properties of P2P file exchange swarms from the queueing perspective, where the service rate received by nodes depends on the server and varied with the number of nodes. Yu et al [10] used the repairable M/M/2 queueing model to study wireless communication network, and proposed a strategy to decrease energy consumption. Si et al [11] developed an M/M/c queueing model with impatient customers and repairable fault for unstructured distributed P2P network, taking into account the node dynamic process and concluded that an appropriate increase in node conversion rate can avoid system congestion and improve energy savings.…”

Nowadays, P2P (Peer-to-Peer) absolutely dominates the Internet as a traffic in content distribution and sharing service, the issue of energy consumption has emerged as a hot issue. This paper combines the basic theoretical knowledge of queueing theory with the currently more popular hybrid P2P network structure model. In order to address the problem of wasted energy consumption generated by unnecessary online behavior of nodes, the working sleep mechanism for the serving nodes is introduced, and the synchronous multiple working vacation strategy is also adopted to decrease the system energy consumption. In the meantime, negative customer and feedback strategies are introduced. Then a queueing model with working vacation and repairable fault is built, which used to simulate the resource transmission process of P2P and to study the performance of P2P sharing system. The steady-state probability vector is derived by employing quasi-birth-and-death process (QBD) and matrix-geometric solution method. And the expressions for system performance indicators, such as the average delay, are obtained by employing Gauss-Seidel iteration method. Through numerical experiments, the performance indicators of the P2P resource sharing system are studied, which provides a theoretical basis to decrease online energy consumption of nodes in the P2P network system. And through employing Nash equilibrium and social optimal strategy, the value of the social maximum benefit under the social optimization is obtained.
