significance of human configuration errors that slow down the resolution process or even
cause it to fail. Part of the problem is the complexity of the DNS delegation process, which
is based on cooperation across different organizations. Therefore, an integration of the
EPCglobal Network with ONS as proposed into core business processes could leave even
formerly non-IT related companies dependable on the availability of Internet services.
This will most probably increase overall business risk.
9.3.4 Named Data Networking
Shang et al. [33] discussed how named data networking (NDN) addresses the root causes
of the various challenges in IoT and can help achieve the IoT vision in a more secure,
straightforward, and innovation-friendly manner. The first challenge of IoT is how to
enable all different types of digital devices that provide IoT functionality to communicate
locally and globally. The second is how to consistently and securely communicate the data
associated with the things themselves, once connectivity is achieved.
NDN fundamentally shifts the network communication model from host-centric to
data-centric. Instead of sending packets between source and destination devices identified
by numeric IP addresses, NDN disseminates named data at the network level, forwarding directly on names that carry application semantics. Moreover, each packet in NDN is
secured at the time of production, allowing data replication anywhere in the network and
preserving security properties of the data over its lifetime. Amadeo et al. [34] proposed
a baseline NDN framework for the support of reliable retrieval of data from different
wireless producers which can answer to the same Interest packet (e.g., a monitoring application collecting environmental data from sensors in a target area). The solution is evaluated through simulations in NDN SIM and achieved results show that, by leveraging the
concept of excluded field and ad hoc defined schemes for data suppression and collision
avoidance, it leads to improved performance in terms of data collection time and network
overhead.
The research community is currently exploring cutting-edge approaches to transform
the Internet, as we know it today, into a system more capable of and tailored for effective
content distribution, according to today’s (and tomorrow’s) needs. Information-centric networking (ICN) has been recently proposed for this purpose and is inspiring the design of
the future Internet architecture. Unlike the IP-address-centric networking of the current
Internet, in ICN every piece of content has a unique, persistent, location-independent name,
which is directly used by applications for accessing data. This revolutionary paradigm
also provides content-based security regardless of the distribution channel and enables
in-network data caching. Amadeo et al. [35] discussed the challenges and opportunities
in ICN.
9.4 Efficient Naming, Addressing, and Profile Services in
IoT Sensory Environments
In this section we discuss the naming, addressing, and profile services in IoT introduced by Li et al. [36]. They introduced a NAPS server to interconnect different platforms in the IoT environment. NAPS serves as the key module at the back-end data
center to aid the efficient upstream sensory data collection, content-based data filtering,
