In wireless sensor network, sensor nodes will watch the atmosphere and sink will be the base station. There are primarily two common attacks that interrupt the communication in wireless sensor networks, they are packet dropping and packet updating. To conquer these attacks many schemes are proposed, but only some are working capably to recognize the intruders that dropping packets but not the updaters. Criterion authentication mechanisms can't prevent this attack if the opponent has compromised one or small number of sensor nodes.
