Detecting denial of service attacks by analysing network traffic in wireless sensor networks

Abstract

Intrusion detection in Wireless Sensor Network (WSN) is of practical interest in many applications. The intrusion detection is defined as a mechanism for a WSN to detect the existence of inappropriate, incorrect, or anomalous moving attackers. A WSN tries to detect the unauthorized access in wireless network. The unauthorized access is called INTRUSIONS. So there is a need to protect the computer system from these intrusions i.e. wireless intrusion detection system (WIDS) is required. By analyzing the network traffic and comparing the normal traffic pattern against the suspicious pattern we can detect those intrusions. Denial-of-Service attacks, and jamming in particular, are a threat to wireless networks because they are at the same time easy to mount and difficult to detect and stop. © 2014 Kavala Institute of Technology.
