As more and more wireless devices use the 2.4 GHz radio spectrum, the coexistence of 2.4 GHz wireless devices operating in one place has become a hot topic. With low transmit power, the widely deployed IEEE 802.15.4-based networks are easily interfered with by other 2.4 GHz wireless networks, such as IEEE 802.11. IEEE 802.15.4-based wireless networks have paid great attention to the coexistence between themselves and with other non-IEEE 802.15.4 wireless networks. This problem has been further promoted by two new industry wireless standards, WirelessHART and ISA100, to meet special industry requirements. This paper surveys the studies on the coexistence between IEEE 802.11 and IEEE 802.15.4-based networks following the general analysis method of "question-analysis-solution." Based on the survey study, we discuss about some open research issues and developments in this field.

“…Ref [ 76 ] presents a mathematical model that serves as an interference avoiding mechanism for aggregated interference to the primary networks. In a bid to explore the possibilities of CRSNs amidst various interferences, [ 9 ] proposes a model that determines the optimum transmit power required to achieve a desired throughput by measuring the interference temperature. However, various studies have consistently shown the limitations of this method.…”

“…In extreme cases where all other networks (e.g., medical sensor networks, security networks, disaster communications, PDAs, Bluetooth devices and many more applications envisioned in the very near future) compete for these four channels, the congestion issue becomes more urgent. The authors of [ 8 , 9 ] have shown that IEEE 802.11 degrades the performance of 802.15.4 when they operate in overlapping bands, and in [ 7 ] a highly variable IEEE 804.15.4 performance drop of approximately 41% was demonstrated. Furthermore, as computing/networking heads toward ubiquity, various WSNs will form a great percentage of this phenomenon.…”

Interest in the cognitive radio sensor network (CRSN) paradigm has gradually grown among researchers. This concept seeks to fuse the benefits of dynamic spectrum access into the sensor network, making it a potential player in the next generation (NextGen) network, which is characterized by ubiquity. Notwithstanding its massive potential, little research activity has been dedicated to the network layer. By contrast, we find recent research trends focusing on the physical layer, the link layer and the transport layers. The fact that the cross-layer approach is imperative, due to the resource-constrained nature of CRSNs, can make the design of unique solutions non-trivial in this respect. This paper seeks to explore possible design opportunities with wireless sensor networks (WSNs), cognitive radio ad-hoc networks (CRAHNs) and cross-layer considerations for implementing viable CRSN routing solutions. Additionally, a detailed performance evaluation of WSN routing strategies in a cognitive radio environment is performed to expose research gaps. With this work, we intend to lay a foundation for developing CRSN routing solutions and to establish a basis for future work in this area.

“…Therefore the cognitive radio (CR) technology is introduced. CR could share the spectrum with licensed user by spectrum sensing and allocation algorithm without disturbing the licensed user [2] . Nowadays the spectrum resource is more and more precious, if we could apply CR technology to the device working at ISM band, it will be a big step for both equipment efficiency and improving spectrum utilization.…”

The wireless spectrum resource becomes more and more precious so that the efficiently use of the limit resource has been a hot research point. In order to efficiently use the ISM bands, we focused on the characteristics and rules of the Bluetooth system as the primary frequency hopping system at ISM 2.4GHz band and found out that in the ISM band there still are many "spectrum hole" unused in time domain. Using the cognitive radio technology, we propose a way of idle channel time space estimation and a spectrum sharing strategy. The simulation shows that the cognitive user could quickly find out the spectrum hole and accessing the idle channel without interfering the authorized user.
