Abstract: Wireless Sensor Network consists of hundreds or thousands of sensor nodes. Impractical to maintain topology and protect each sensor nodes from attack. Wireless Sensor Network is often deployed in an unattended and hostile environment to perform the monitoring and data collection tasks. When sensor nodes are deployed in such an environment, sensor network lacks in physical protection and is subject to insertion of malicious node. After that an adversary may launch various attacks to disrupt the innetwork communication through malicious node. In such attacks malicious node behave like normal nodes by selectively drop packets for make it harder to detect their malicious nature. Many schemes have been proposed to detect malicious nodes, but very few can identify attacks. But those proposals are send redundant packets, consume more energy and storage to identify malicious nodes. A simple and effective scheme proposed as Stop Transmit and Listen (STL) to find the malicious node. Each node is having the built-in time limit to stop their transmission. For every few seconds every node stops their transmission and listens for malicious behavior. Malicious nodes are not aware of non-transmitting time. If malicious node sends or forwards the data in nontransmitting time, malicious node is caught by their neighbor nodes in the network.
