Modified Optimum Pricing Algorithm with Delayed CSI feedback for Spectrum sharing in D2D based Vehicular Networks

Abstract

The next-generation wireless network has to handle a large amount of data transmission resources which need study on new technologies like machine2 machine communication, device 2 device communication etc., the integration of social network and device 2 device communication in 5G and upcoming 6G networks poses very important challenges in various QoS parameter. This paves way for improvement of spectral and energy efficiency for a vehicular communication network. In this paper, clustering schemes and robust power control schemes are utilized to achieve the improved spectral and energy efficiency. Clustering schemes are established to form stable clusters and pricing-based algorithms are used for achieving robust power control. The two robust power control algorithms the fixed price algorithm and optimized price algorithm are analyzed. And to compromise the trade-off produced by these algorithms, a pricing-based algorithm with delayed channel state information feedback for D2D (Device-to-Device) based vehicular communication network is developed in this paper. The results obtained shows that the proposed algorithm is effective.

Enhancing V2I and V2V Communication in Vehicular Networks through GSA-BPSO Optimized Neural Network

“…These gains are associated with the transmission from the 𝑚 𝑡ℎ V2I transmitter to the 𝑘 𝑡ℎ V2V vehicle through the 𝑓 𝑡ℎ RB. Moreover, the interference channel 𝑔 𝑚,𝑘 from the first V2V receiver, routed to the base station via the 𝑘 𝑡ℎ V2V receiver's interference channel, is taken into consideration [20,21]. This paper is focusing on the communication latency requirement for vehicular-to-vehicular (V2V) links.…”

“…However, a limitation of the approach lies in its reliance on randomized algorithms for resource allocation, potentially leading to unpredictable outcomes and reduced control over resource distribution. The authors of [21] investigated a joint approach to cluster formation and robust power control in D2D-based vehicular networks. To mitigate inherent trade-offs, an optimal price C approach with delayed CSI feedback is suggested.…”

Resource allocation in vehicular network based on sparrow search algorithm and hyper-graph in the presence of multiple cellular users

“…In the spectrum access algorithm considering the needs of V2V and V2I links, a competition-based opportunistic spectrum access scheme (Song and Yuan, 2019) for V2V link sharing the spectrum of V2I is designed. To improve spectral efficiency of V2V links with delayed Channel State Information (CSI) feedback, Thulasimani and Antinita (2021) propose a clustered and robust power control scheme. Based on the slowly fading CSI, some literature have studied the resource allocation scheme to improve the throughput of V2I links in V2X networks where multiple V2V links share spectrum with V2I.…”
