“…Recently, such services are supported by the various communication networks such as dedicated short‐range communications [6, 7] and LTE networks [8–10]. In addition, vehicular scenarios have also been widely investigated in the cooperative relaying networks (see [11–14] and the references therein). As a part of future generation wireless communications, a large number of autonomous/semi‐autonomous vehicles will take the road and engage with ITS services, because of which a huge surge in the wireless data traffic is expected over the limited spectrum allocated for vehicular networks.…”

“…Also, the mathematical form of Nakagami-m model is more analytical tractable. In the works [24][25][26][27], a cooperative communication network is investigated over the generalized fading channel model. In [24], the authors investigate the impact of latency on full-duplex AF relaying network over the Nakagami-m fading channel distribution.…”

“…Therefore, one relay is opportunistically selected among K relay nodes to establish their communications. But in the works [24][25][26][27], the authors did not consider the real-time propagation constraints such as time selectivity and imperfect CSI. The time-selective Nakagami-m fading channel model best captures wireless channels for mobile nodes and has been well investigated for machine-to-machine (M2M) [28] and device-to-device [29] wireless communication scenarios and experiential models based on Nakagami-m fading channel.…”

In this paper, we consider the selective decode and forward cooperative communication system and investigate its performance over time-selective fading in the presence of nodes' mobility and channel estimation errors. Closed-form expressions for the outage probability (OP) and per-block average pairwise error probability (PEP) are derived, considering constraints at the relay, source, and destination nodes. We assume that both dual and multiple hops are subject to independent but non-identically distributed time-selective Nakagami-m fading channel. It has been observed that with an increase in the value of shape parameter and link strength of the relay-to-destination (RD) fading link gain, the per-block average PEP performance improves. Also increasing RD link gain is more significant than increasing the shape parameter of the RD link. The OP performance for optimal power allocation factors is better than its performance for equal power allocation factors. It is demonstrated that the OP decreases with increasing the value of distance-dependent power transfer factors (PTFs). Further, it has been observed that due to the mobility of nodes and imperfect channel state information, the PEP performance of the system experiences degradation, especially for high values of signal-to-noise ratio. Furthermore, when all the nodes are static and the estimation processes are perfect, the asymptotic error floors vanish, i.e., the nodes' mobility impact is removed. Monte Carlo simulation results confirm the accuracy of the analytical results.

Rapid emergence of wireless sensor networks (WSN) faces significant challenges due to limited battery life capacity of composing sensor nodes. It is substantial to construct efficient techniques to prolong the battery life of the connected sensors in order to derive their full potential in the future Internet of Things (IoT) paradigm. For that purpose, different energy harvesting (EH) schemes are relying on a wide array of sources. Following the same objective, in this work, we have observed a time-switching EH for half-duplex (HD) bidirectional WSN, which performed in-between relaying over Hoyt fading channels. For its comprehensive performance analysis, rapidly converging infinite-series expressions have been provided with focus on the outage probability (OP) and achievable throughput of the hardware-impaired system. Additionally, asymptotic behavior of these performance measures has also been provided. Further, an approach to the symbol-error probability (SEP) analysis is also presented in the context of the observed system. Finally, we consider the shadowing influence along the WSN propagation path. Performance analysis of observed EH system operating over Rician-shadowed fading channels has been carried out, with deriving exact corresponding infinite-series expressions for outage probability (OP) and achievable throughput of the system under the hardware impairment conditions. In addition, bidirectional relaying in a mixed fading environment has been considered.
