Wireless sensor networks are specified ad-hoc networks. They are characterized by their limited computing power and energy constraints because they are generally limited in memory, power and computational ability. Thus they can only transmit data to a limited distance. The major challenges of wireless sensor networks are security. This paper proposes a study of security in this kind of network. Here a list of attacks with their specificities and vulnerabilities are presented. Based on the location information presence of fake data can be identified.
