DOS Attacks and Defenses at the Network Layer in AD-HOC and Sensor Wireless Networks, Wireless AD-HOC Sensor Networks: A Short Survey

Adhoc and sensor wireless networks are challenging and promising field for researchers. These networkingtechnology are not only significant on science and engineering but important on a broad range of applications such as critical infrastructure protection and security, disaster relief operations, biodiversity mapping, medicine and healthcare etc. Wireless Sensor Network applications require Wireless-Adhoc Networking techniques, but both are easily susceptible to various security attacks. This paper mainly focus on DOS attacks and its defenses at the network layer proposed by different researchers in adhoc, sensor wireless networks and the vampire attacks at the routing protocol layer in the new application of wireless adhoc sensor networks.
