Internet of Things (IoT) has attracted the interest of the research community, at a great manner the last years. It is one of the most hot topics, for future and current research directions, regarding both academia and industry sectors. Security and privacy issues of IoT are proven targets of great importance. This work brings together models, schemes and implementation aspects, regarding the alternative technologies of IoT. It focusses on the knowledge for the implementation efficiency, basically in hardware terms, of communications confidentiality, user authentication, data integrity and services availability. Special attention has been paid regarding attacks and modern threats, as well as to countermeasures against them. Different IoT infrastructures are examined and alternative trust models are presented. Policy issues are also considered.

Tutorial 2: Performance guarantees in Wireless Sensor Networks: Issues, challenges and solutions, from congestion control to mobility management approaches

Performance, in terms of throughput, time delay and power consumption, is now a dominating factor that leads research in WSNs. Several emerging WSN applications need immediate and guaranteed actions. In such environments, data has to be transported reliably and in time through the wireless sensor network.

In this tutorial we present and analyze the issues and challenges that need to be faced when attempting to design WSNs with performance guarantees.

After this analysis, we present specific solutions that guarantee high and stable performance of 

  • Congestion occurs
  • Mobile nodes are employed in the network.

In particular, we present two different congestion control solutions as well as a mobility management approach.

The first congestion control approach is based on a nature‐inspired model. This model adapts techniques from nature and demonstrates their usefulness in combating congestion in WSNs under variable network and traffic conditions focusing on performance guarantees.

The second congestion control approach focuses on employing the unused nodes by creating alternative paths to the sinks without affecting the performance of the network.

Finally, we present a mobility management protocol that can be applied in critical applications and that efficiently maintains the connectivity of the mobile node by controlling the handoff procedure (triggering and execution).
