“…We previously used FMCW radar as a means for RadCom [35], [36]. It was shown that consideration of higher layers improved both radar and communication capabilities compared to coexistence studies focusing solely on the physical layer [17]. The analysis of the R2R interference conducted in [35], showed that higher-layer coordination of automotive radars through communications decreased R2R interference for two facing radars, whereas the same RadCom system was shown to increase the probability of detection of vulnerable road users by eliminating ghost targets [36].…”

In the automotive sector, both radars and wireless communication are susceptible to interference. However, combining the radar and communication systems, i.e., radio frequency (RF) communications and sensing convergence, has the potential to mitigate interference in both systems. This article analyses the mutual interference of spectrally coexistent frequency modulated continuous wave (FMCW) radar and communication systems in terms of occurrence probability and impact, and introduces RadChat, a distributed networking protocol for mitigation of interference among FMCW based automotive radars, including self-interference, using radar communications. The results show that RadChat can significantly reduce radar mutual interference in single-hop vehicular networks in less than 80 ms.

“…Apart from that, since the available radio spectrum is today a scarce resource (cf [7] for example), another challenge faced is to develop techniques which enable a better coordination between legacy and future services, especially considering this new machine-type communication environment and its large-scale implementation. Despite of the spectrum regulation and policy still being considered as a dry subject since the earliest days of radio communication, the need to reconsider the static longterm exclusivity of the spectrum via licensed regulation procedures, as well as the encouragement of the techniques which enable the coexistence of different networks, become a key element to permit a proper expansion of these new services [8].…”

In this paper, we present a realistic use case in order to investigate the feasibility of a secondary service transmission over an existent satellite infrastructure. By introducing the overlay cognitive radio paradigm towards satellite communications, we compute a theoretical achievable data rate greater than 16 kbps for the secondary service, which is suitable for most M2M applications. Using simulation results, we show that this can be achieved while preserving the primary service performance. In addition, a system design framework is discussed in order to dimension such systems.

“…Such complex environments comprise a huge number of heterogeneous devices from different vendors that may use different operating systems and protocols [2]. Consequently, different challenges may arise during the deployment of IoT applications including the scalability, trust relationship between networks and devices, devices' resource limitation, and the diversity of applications requirements and channel utilization [3]. Thus, there is a huge need to develop a unified stack and underlying architecture to support different kind of devices, and easily connect with the Internet infrastructure.…”

Time Slotted Channel Hopping (TSCH) is one of the most used MAC mechanisms introduced by the new amendment IEEE 802.15.4e. It combines both slotted access with channel hopping technique to allow multiple communications while exploiting the 16 available channels of 2.4GHz band. The channel hopping mechanism of 802.15.4e considers an interference-free environment and does not specify how to build and manage a schedule for communication purpose. In this paper, we propose a new distributed channel hopping scheme that exploits Latin rectangles to avoid interference and collisions. In essence, the scheduling of links is performed by Latin rectangles where rows are channel offsets and columns are slot offsets. Thus, the frequency of communication is derived using Latin rectangles. Consequently, interference and multi-path fading are mitigated with more reliability and robustness. The efficiency of the proposed scheme has been validated by extensive simulation.
