Wireless Sensor Network attacks: An overview and critical analysis

Wireless Sensor Networks (WSN) are gaining a lot of attention from researchers due to their massive applications. Network security is one of the important requirements of those applications. This paper analyses possible network attacks that is essential for researchers in developing robust security countermeasure. In this study, a systematic overview of different kinds of attacks for WSNs has been carried out and a critical analysis of the existing research results is presented. Also we propose five new attacks for WSNs. Furthermore, based on our analysis, we suggest to develop efficient attacking methods; to be called as cross-layer attacks, which combine and exploits the merits of specific attacks in different layers.
