An Efficient Routing Protocol for Full-Duplex Software Defined Radios

Abstract

Due to the rise in Internet of Things applications, wireless communication requirements are escalating quickly, which motivates researchers to create secondary networks that take advantage of primary networks' spectrum gaps. Cognitive Radio (CR) technology is utilized in Ad-Hoc Networks (AHNs) instead of infrastructure-based networks because AHNs have lower cost, greater coverage, and require less maintenance. In addition, software defined networking offers a cutting-edge framework for managing network resources that solves a number of problems with the management of network resources in CR Networks (CRNs). Moreover, researchers are becoming more and more interested in In-Band-Full-Duplex (IBFD) in CRNs. The combination of IBFD and CRNs improves the network's performance greatly because of the effective dynamic spectrum access. Hence, we offer an adaptive Full-Duplex (FD) CRNs routing protocol that utilize common control channel. Our protocol employs adaptive FD communication, where the secondary users change their communication mode in response to the primary users' activity on the spectrum. Further, communication modes used in our work are FD Transmit and Sense (FDTS), FD Transmit and Receive (FDTR), and Sensing Only (SO). A Java language simulator for IBFD-CRNs that had already been published in the literature was used to assess the performance of our protocol. Additionally, we compare the effectiveness of our system with that of the Broadcast Full-Duplex Routing Protocol (BC-FDRP), an earlier protocol. Throughput is the performance metric used.
