Table 2

Contrast of difference mobile paths.

Different mobile path planning	Distance of movement	Nodes of unresolved localization	Localization error
Case : path planning algorithm of grid scan (communication radius = 30 m; number of beacon nodes = 25)	600	1	0.08767
Case : random way point mobile path (communication radius = 30 m; number of beacon nodes = 25)	329	42	0.38701
Case : random way point mobile path (communication radius = 30 m; number of beacon nodes = 50)	783	7	0.16785
