Table 3

Notation for ESCS-Init() and ESCS().

Symbol	Meaning
	Amount of residual energy of node
	Energy threshold for changing mode,
	1 if sensor node is in energy-rich mode, otherwise 0
ψ	Energy window to prevent frequent change of the mode
AES	One of the symmetric-key encryption algorithms
ECIES	One of the public-key encryption algorithms
Period	Periodic invocation cycle of the ESCS()
