To address the “broadcast storm” problem associated with flooding-based route discovery mechanism of reactive routing protocols, probabilistic approaches are suggested in the literature. In the earlier work, Gossip flooding mechanism of Haas et.al. was extended with signal quality, to propose channel quality based adaptive gossip flooding mechanism for AODV (CQAG-AODV). Following the cross-layer design principle, CQAG-AODV algorithm tried to discover robust routes, as well as address the “broadcast storm” problem by controlling the rebroadcast probability of Route request (RREQ) packets on the basis of signal strength experienced at the physical layer. This paper investigates the connectivity of CQAG-AODV through theoretical and simulation analysis. Results show that, by accounting the signal strength in the route discovery process, not only does the proposed algorithm floods a lesser number of route requests and controls the broadcast storm, but also maintains a higher level of connectivity to offer high packet delivery ratio; independent of network density and node mobility. Moreover, due to controlled routing overhead and robust route discovery, channel quality based adaptive flooding mechanism offers fringe benefit of energy efficiency as well. CQAG-AODV thus proves its suitability in a variety of use cases of multi-hop ad hoc networks including WSNs and VANETs.

“…The objective of routing is to deliver data packets from sources to destinations. Although plenty of routing schemes [12][13][14][15][16] for traditional cognitive radio networks and wireless sensor networks have been designed, these routing schemes would fail if they are directly used in multi-hop CSNs. Routing in multi-hop CSNs becomes a challenge because of the high dynamic of spectrum availability and quality.…”

Abstract:With the occurrence of Internet of Things (IoT) era, the proliferation of sensors coupled with increasing usage of wireless spectrums especially the ISM band makes it difficult to deploy real-life IoT. Currently, the cognitive radio technology enables sensors transmit data packets among them through the licensed spectrum bands as well as the free ISM bands. Cognitive radio technology has been believed as a promising solution to the congestion problem of spectrum utilization. The dynamic spectrum access technology enables secondary users (SUs) access wireless channel bands that is originally licensed to primary users (PUs). Due to the high dynamic of spectrum availability, it is a challenge to design an efficient routing approach for SUs in Cognitive Sensor Networks (CSNs). We estimate the spectrum availability and spectrum quality from the view of both the global statistical spectrum usage and local instant spectrum status, and then introduce novel routing metrics to consider the estimation. In our novel routing metrics, one retransmission is allowed to restrict the number of rerouting and then increase the routing performance. Then, the related two routing algorithms according to the proposed routing metrics are designed. Finally, our routing algorithms in extensive simulations are implemented to estimate the routing performance, and we find that the proposed algorithms achieve a significant performance improvement compared with the reference algorithm.Keywords: internet of thing; IoT; cognitive sensor networks; forwarding; spectrum-availability; retransmission IntroductionCurrently, more and more objects with capacity of computing and wireless communication are being designed and deployed to construct pervasive computing environments, which leads to the era of the Internet of Things (IoT) [1]. With the wide deployment of wireless objects and mobile applications, the unlicensed portions of wireless spectrums especially the ISM band have become increasingly crowded. The Federal Communications Commission (FCC) stated current spectrum resources are static allocated and utilized in some limited geographical regions, and that the expectation of utilization is largely under-utilized [2]. To efficiently increase the ratio of the spectrum usage, cognitive radio emerged as a promising solution to the problem of low ratio of spectrum utilization [3,4]. In cognitive radio environments, primary users (PUs) coexist with secondary users (SUs), in which SUs usually carry cognitive radio devices, which enable them scan and sense the surrounding spectrum utilization; when finding spectral holes, in which no PUs access the related spectrum bands, Sus can opportunistically access these spectrums by adjusting their spectrum bands dynamically; in the process of spectrum usage, an SU should abandon its spectrum band at once and then switch to other available spectrum band when a PU arrives.Recently, researchers have gained much attention to multi-hop Cognitive Sensor Network (CRSN) [5][6][7][8][9]. A multi-hop CRSN consists...
