Blockchain-oriented symbiotic communications for secure and green next-gen wireless networks

Abstract Symbiotic wireless communication (SWC) is a novel paradigm, which allows several networks to coexist and share resources with each other through mutual interactions, just as it is the case within the natural ecological systems. The approach has been perceived as a viable measure of resolving energy inefficiency and scarcity of the spectrum in the future wireless communication networks. Nevertheless, sharing of resources and services in SWC places has not been an easy task because of untrustworthy trust systems across diverse platforms. To deal with this challenge, this paper will present a symbiotic blockchain wireless network (SBWN) which will combine blockchain technology and SWC to provide safe and effective communication. The framework proposed makes use of cognitive backscatter communication and energy-efficient sharding mechanism to minimize the processing overhead and improve system performance. The simulation results show that SBWN ensures up to 60% of energy efficiency, almost 19% higher packet delivery ratio, almost 80 percent reduced latency, and around 88% enhanced throughput over traditional baseline techniques. These findings show that the proposed architecture has the capacity to scale to support future wireless communication systems in a reliable, and sustainable manner.
