“…We use a SDR-based architecture to implement CR which can exploit frequency, time, and power dimensions of the resource space to improve coexistence in the 2.4 GHz ISM band. Experimental results using this testbed initially reported in [13] are further improved by utilizing additional simulations. Results of a fast hardware defined radio (HDR)-based implementation are also provided in this contribution.…”

The need for multiple radio systems in overlapping regions of a factory floor introduces a coexistence problem. The current research challenge is to design and realize radio systems that should be able to achieve a desired quality-of-service (QoS) in harsh, time-varying, coexisting industrial environments. Conventional coexistence solutions attempt to accommodate coexisting systems in a single dimension, mostly in the frequency dimension. The concept of multidimensional electromagnetic (EM) space utilization provides optimal opportunities to achieve coexistence optimized solutions. It can revolutionarily augment the shareable capacity of the resource space and provide optimal coexisting capabilities of radio systems.A software defined radio (SDR)-based cognitive radio (CR) is realized which can exploit the frequency, time, and power dimensions of the EM space to improve coexistence in the 2.4 GHz industrial, scientific, and medical (ISM) band. Furthermore, a conventional hardware defined radio (HDR) and additional simulations are used to test and prove the feasibility of the triple EM space utilization. Joint results of these experiments are presented in this contribution. Additionally, we present a novel computational efficient algorithm to detect cyclic properties of industrial wireless systems.

Cognitive radio with spectrum sensing and spectrum reuse has great opportunities for industrial networking. Adapting to the current interference situation and utilising the available frequencies in an effective manner can greatly improve the data delivery capabilities. At the same time, real-time demands must be met. In this paper, we present a medium access control protocol supporting dynamic spectrum allocation as done in cognitive radio networks, providing deterministic medium access for heterogeneous traffic. The possibility of spectrum sensing in the nodes opens up for the possibility of increasing successful data transmissions, and a real-time analysis framework with three formalized constraints to be tested provides support for guaranteed timely treatment of hard real-time traffic. The real-time analysis framework includes a new type of delay check that more exactly bounds the delay compared to earlier work. Simulation experiments and performance comparisons are provided.
