An Efficient Node Localization Approach with RSSI for Randomly Deployed Wireless Sensor Networks

Table 1

Contrast of two kinds of localization scheme.

Deployment pattern of beacon node	Average connectivity of network	Average number of neighbor beacon nodes	Nodes of unresolved localization	Localization error
Case : beacon randomly deployed (communication radius = 30 m; beacon nodes = 25)	25.008	4.216	28	0.12441
Case : mobile beacon node (communication radius = 30 m; number of beacon nodes = 25)	26.208	4.992	1	0.08767
