For the sake of fulfilling the ever-increasing demands on the Internet of Things (IoT) applications, researchers are implementing Cognitive Radio (CR) technology in Ad-Hoc Networks (AHNs). Moreover, In-Band Full-Duplex (IBFD) technology in CRAHNs is gaining scholars’ interests recently. Hence, we are considering non-time-slotted IBFD-CRAHNs to clear up the reactivation failure and frequent hand-off problems confronting Primary Users (PUs) and Secondary Users (SUs), respectively, in Half-Duplex (HD) CRAHNs. We propose two HD-CRAHN routing protocols without a common control channel intended for practicality. This is accomplished by adopting multi- and unicast transmissions in the Route Request Packets (RRQPs) delivery. The first protocol is tested with data transmission in HD mode. However, the second routing protocol adopts a channel assignment technique proposed in the literature for FD communications; thus, we apply FD data transmission on it. Additionally, this paper offers an IBFD-based CRAHN routing protocol that broadcasts the RRQP over the channels that have SUs sensing them or even transmitting over them. This is possible because of two patents that allow wireless nodes to receive (transmit) in a sweeping manner while transmitting to (receiving from) another node. The three protocols' performance is studied and compared with the most pertinent and recent protocol named Probabilistic and Deterministic Path Selection (PDPS) using an exclusive simulator, built-in Java language, over the simulator used in PDPS experiments. As far as the throughput performance metric is concerned, our simulation results show noticeable and undeniable improvements over the PDPS protocol.

适用于IoT环境的半双工和全双工认知无线电Ad-Hoc网络的高效路由协议

为了满足对物联网(IoT)应用的不断增长的需求,研究人员正在Ad-Hoc网络(AHN)中实现认知无线电(CR)技术。此外,CRAHN中的带内全双工(IBFD)技术近来引起了学者的兴趣。因此,我们正在考虑使用非时隙IBFD-CRAHN来分别清除半双工(HD)CRAHN中主要用户(PU)和次要用户(SU)遇到的重新激活失败和频繁切换的问题。我们提出了两种HD-CRAHN路由协议,它们没有旨在实用的公共控制通道。这是通过在路由请求包(RRQP)传递中采用多播和单播传输来实现的。在HD模式下使用数据传输测试第一个协议。然而,第二种路由协议采用文献中提出的用于FD通信的信道分配技术。因此,我们对其应用FD数据传输。此外,本文提供了一种基于IBFD的CRAHN路由协议,该协议在具有SU感知甚至通过其传输的SU的信道上广播RRQP。这是有可能的,因为有两项专利允许无线节点在传输到另一个节点(从另一个节点接收)时以扫掠的方式接收(传输)。研究了这三种协议的性能,并与最相关的最新协议(称为概率和确定性路径选择(PDPS))进行了比较,该协议使用专用的内置Java语言模拟器,而不是PDPS实验中使用的模拟器。就吞吐量性能指标而言,
