From an application’s point of view

From an application’s point of view, the driving force
behind research in WSNs is to develop systems that
can operate unattended for large periods. Besides energy
consumption considerations, the unattended nature of
the deployed WSNs raises administration problems and
appoints the security as an additional critical element in
the network design [3]. As identified in [4-6], WSNs are
susceptible to various types of attacks or to node compromises
that exploit known and unknown vulnerabilities
of protocols, software, and hardware, and threaten the
security, integrity, authenticity, and availability of data that
reside in these networked systems.
