A Study of the Security Problems of Wireless Sensor Networks into the Context of the Internet of Things

The Internet of Things is an integral part of the Internet of the future and can defined as a global and dynamic network infrastructure based on interoperable communication protocols where real and virtual Things have an identity or address that through smart interfaces are perfectly integrated into an information network. Among the connected objects will be the Wireless Sensor Networks WSN that can generate, collect, store and share information between themselves and with the centralized authentication nodes called "Base stations". The information collected by the sensor nodes must protected against attacks and forgery in the collection and transfer of data. Because connected sensor nodes have low computing, memory, and power capabilities, and access to the radio medium is highly consumer of resources, traditional cryptographic protocols are not suitable for connected Things because of their heterogeneity. In this paper will present the various attacks against WSN in the context of IoT and proposed solutions exist in literature to securing the network against these attacks.
