With the exciting progress of wireless sensor networks (WSN) research, we predict that in 5-10 years, the world will be full of low-power wireless sensor devices. Due to the independent design and development, coupled with the unexpected dynamics during the deployment of networks and coexisting devices, the limited frequency spectrum will be very full. The Wireless Sensor Network (WSN) is a new and exciting technology that applies to environmental monitoring, agriculture, medical care, intelligent buildings, factory monitoring and automation, and numerous military applications. A WSN can also be considered as the underlying infrastructure that will be an integral part of future ubiquitous and embedded computing applications.
In recent years, industrial, scientific and medical (ISM) bands have been intensively shared with unlicensed wireless communications applications such as wireless sensor networks (WSN). With the burgeoning popularity of sensor devices and the growing installation of wireless sensor nodes, cross-technology interference (CTI) has become a significant problem in the real world. Due to CTI, wireless devices suffer from important communication dilemma. On the other hand, the ISM band, as the main means of communication of WSN, must be reasonably used in an efficient and effective way. Comprehensive approaches have been proposed to explore the use of spectrum in WSN. However, there is no such organization that systematically organizes these works. To achieve this goal, we first illustrate the background of WSN and the use of the spectrum. Our concern for CTI is then noted. We will later demonstrate the importance of efficient spectrum use. Finally, through the classification and summary of related recent works, we provide an essential structure of research in the field titled and the detailed intellectual merits of the published works. Our survey covers more than 80 studies in the field of spectrum use in WSN.
