A survey of wireless sensor network security in the context of Internet of Things

Today, the common vision of smart components is usually based on the concept of the Internet of Things (IoT). Intelligent infrastructures combine sensor networks, network connectivity and software to oversee and analyze complex systems to identify inefficiencies and inform operational decision-making. Wireless Sensor nodes collect operational information over time and provide real-time data on current conditions such as (volcano activities, disaster parameters in general). The security of wireless sensor networks in the world of the Internet of Things is a big challenge, since there are several types of attacks against different layers of OSI model, in their goal is falsified the values of the detected parameters.
