Algorithm 2

Model of Grayhole attack.

N   Network Size

SN Sensor Node

MN Malicious Node

CH Cluster Head

BS Base Station

CM Cluster Member

NC Cluster Heads list

, NC

CH broadcasts the advertisement message (ADV_CH)

x CMs will join CH

  CH creates TDMA schedule

  x CMs send data to CH in the corresponding TDMA time slot

IF CH = MN THEN

  Performs the attack by dropping some packets (randomly or selectively)

ELSE

  Sends aggregated data to BS

ENDIF
