C²S²-LOOP: Circular Chessboard-Based Secure Source Location Privacy Model Using ECC-ALO in WSN

Table 3

Comparison of proposed and previous approaches for different QoS parameters.

Method	Description	Parameters			Demerits
			L
CBA scheme	Source location privacy protection scheme is proposed against global attacker				(i) High energy consumption; (ii) High delay
Grid-based clusters	The network is divided into number of clusters				(i) Wastage of energy; (ii) Large packet delay
SLP-R	Source location privacy using random routing				(i) Increases energy consumption due to random paths; (ii) Privacy leakage
Two-phase routing	Escape angles based random walk routing				(i) It utilized an excess amount of energy; (ii) Network lifetime suffers due to multiple virtual source nodes
