mCSQAM: Service Quality Assessment Model in Mobile Cloud Services Environment

Table 3

Comparison of quality measuring methods.

Methods	Total number of metrics	Quality model hierarchy architecture	Mobile environment support
[6]	1	X	X
[7]	5 (focused on security)	X	X
[8]	10 (focused on performance)	X	X
QoE4CLOUD [9]	0 (not defined)	○; 4-level (hierarchical framework)	△ (SaaS based cloud service only)
[10]	0 (not defined)	X	△ (SaaS based cloud service only)
ADVISE [11, 12]	2 (focused on elasticity)	X	△ (IaaS performance only)
[13]	0 (only suggested using SMI, not defined)	X	△ (SaaS based cloud service only)
[15]	10 or more (security, QoS, and software)	X	△ (SaaS based cloud service only)
Proposed mCSQAM	8 submetrics in 4 main metrics	○; 2-level (hierarchical quality model)	○

“○” means that the research is well supported and “△” means that the research is partly supported hierarchy architecture or mobile environment. By contrast, “X” means that the research is not supported hierarchy architecture or mobile environment.
