Abstract: A Wireless Sensor Network (WSN) comprises of sovereign sensor devices that are used to supervise physical and environmental conditions like temperature and pressure. The WSN is built of hundreds and thousands of recognizing stations called nodes, where each node consists of one or more sensors having a radio transceiver, an internal/external antenna, a microcontroller and a battery. Wireless sensor networks are the systems that are used to communicate by sensing the behavioral changes and the sensing nodes will collect the data and it will get handled. After data handling, the data will be sent to the receiver. The wireless sensor networks have to be fortified from network attacks especially at unfavorable situations because data can easily be obtained by the attackers. There are also some security protocols being implemented in sensor networks. There are some limitations in a wireless sensor network like they have limited storage capacity, limited capability of processing and limited energy to transmit data. These drawbacks can make wireless sensor network different from other networks. The imitation of the attacks are done in the NS2 simulator. By imitating, the performance of the network can be monitored.
