| Summary: | In recent years, the industrial, scientific, and
medical (ISM) bands have been intensively shared with
unlicensed wireless communications applications such as
wireless sensor networks (WSNs). With flourishing popularity
of sensor devices and increasing installation of wireless
sensor nodes, the cross technology interference (CTI) has
become a considerable real-world problem. Because of CTI,
wireless devices suffer significant communication dilemma.
Moreover, ISM band, as the main communication medium
of WSN, should be reasonably utilized in an efficient and
effective manner. Extensive approaches have been proposed
to explore spectrum utilization in WSN. However, there is
no such one, which systematically organizes these works.
In this paper, we present a comprehensive survey on spectrum
utilization in WSNs. To achieve this goal, We first
illustrate the background of WSN and spectrum utilization.
Our concern on CTI is then noted. Later we demonstrate
the importance of efficient spectrum utilization. Eventually,
through classification and summary of recent related works,
we provide an essential structure of research in titled field
and detailed intellectual merits of published works. Our
survey covers more than 80 studies in the scope of spectrum
utilization in WSN. |
