Resumen
DAS, Smita y DEBBARMA, Mrinal Kanti. A Review on Coverage-Hole Boundary Detection Algorithms in Wireless Sensor Networks. Comp. y Sist. [online]. 2020, vol.24, n.1, pp.121-140. Epub 27-Sep-2021. ISSN 2007-9737. https://doi.org/10.13053/cys-24-1-3133.
Wireless sensor nodes are extremely useful in different security and surveillance related applications which may be compromised with the existence of coverage-holes. Coverage-hole is the area in a wireless sensor network (WSN) where sensing or transmitting of data is not achievable and therefore, detecting such region is a prominent research topic in WSN. Subsequent to hole-detection, another significant task is to detect the boundary nodes outlining the coverage-holes. In this paper, we have gone through different research articles describing the various boundary-detection techniques those have been recommended to facilitate hole-detection inside the sensor network. On the basis of the literature review, we have done categorization of the boundary-detection methods, their characteristics, pros & cons and their effect on sensor network's performance for better understanding and future reference.
