Application suggestions for coverage hole detection algorithms.

Field	Desirable features	Applicable categorization
Industry; (control and monitoring of equipments)	Medium scalability, static or hybrid nodes, indoor performance, easy localization, and easy hole healing	[14, 21, 22, 29, 33]
Military; (intrusion detection)	High scalability, outdoor performance, robustness, difficult localization, long network lifetime, and high energy efficiency	[18, 19, 23, 27, 30]
Home; (home automation)	Low scalability, indoor performance, easy localization, and static nodes	[14, 22]
Environment monitoring; (wildlife habitat monitoring, detecting fires, and monitoring seismic activities, temperature, and pressure)	Low degree of coverage, high scalability, mostly outdoor performance, mostly mobile nodes, high energy efficiency, and difficult localization	[16–18, 20, 23, 31]
Automotive; (driving assistance)	High scalability, mobile nodes, outdoor performance, fault tolerance, and good localization	[24, 26, 32, 33]
Agriculture; (field monitoring and predicting crop water requirement)	Medium scalability, easy localization, static nodes, and outdoor performance	[14, 22, 24–26, 28]
