REPLICATION OF ATTACKS IN A WIRELESS SENSOR NETWORK USING NS2

Abstract

A Wireless Sensor Network (WSN) consists of autonomous sensor devices that are used to monitor physical and environmental conditions like temperature, pressure etc. The WSN is built of hundreds and thousands of detection stations called nodes, where each node consists of one or more sensors. Each WSN consists of a radio transceiver, an internal/external antenna, a microcontroller and a battery. Wireless sensor networks are the networks that are used to communicate by sensing the behavioral changes and the sensing nodes will collect the data and it will get processed. After data processing, the data will be communicated to the receiver. There are some organizations that are having very important necessity of wireless networks in organizations such as military, ecology and health. In these kinds of organizations, the wireless sensor networks have to be secured from network attacks especially at unfriendly situations because data can easily be attacked 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 simulation of the attacks are done in the NS2 simulator. By simulating, the performance of the network can be monitored.
