The three most important characteristics of IoT are: (i) the
ability to instrument ordinary objects with a chip and
a communication device, (ii) the interconnection capability, and
(iii) away to provide intelligent services.One critical challenge is
to combine heterogeneous IP or non IP-based objects under the
same network and connect them to the global Internet. The
Internet Engineering Task Force (IETF) and the IPSO Alliance
(2011) with the support of companies such as Cisco, Ericsson,
Oracle, Intel, Google and Motorola, aim to standardize IP (and
more specifically IPv6) for embedded systems in order to
homogenize heterogeneous smart objects. The incompatibility
between smart devices and their supported technologies,
especially in different layers, leads to difficulties in their
collaboration, as well as in their secure and trustworthy interdependence
with their environment and logged in followers.
