 The next generation will be the interconnection
between objects (such as IoT, M2M, V2V, and
Nano IoT etc.) to create a smart environment.
 Only in 2011 did the number of interconnected
devices on the planet overtake the actual number
of people.
 Currently there are 9 billion interconnected
devices and it is expected to reach 24 billion
devices by 2020.
 According to the GSMA, this amounts to $1.3
trillion revenue opportunities for mobile network
operators alone spanning vertical segments such
as health, automotive, utilities and consumer
electronics.

 One of the signification solution for keeping up with the dynamicity of the
hardware and software for reliable data collection is Software Defined
Network (SDN).
 DSN is the physical separation of the network control plane from the Data
plane, and where a control plane controls several devices.

 One of the major goals in SDN
is to be able to interact with the
networking equipment (e.g.,
routers, switches).
 In this way, one can get a global
view of the entire network and
will be able to make global
changes without having to
access to each device’s .
 Eventually, various large-scale
network architectures can be
deployed and maintained with
ease while still featuring
resiliency and robustness.

 Smart Grid (SG) is an intelligent
electric power infrastructure that collects
information via modern communication
technologies to provide efﬁcient,
reliable, and cost-saving energy
generation and distribution.
 The recent integration of information
and communication technology (ICT)
systems has transformed the traditional
power grid into a smart grid.
 With two-way communication,
customers can follow price changes and
incentive offers to make decisions on
energy consumption accordingly.

 HAN include sending/ receiving
electrical measurement data from an
appliance to a controller.
 HAN applications do not require data
to be transmitted at high frequency
and all applications occur inside
residential/commercial/industrial
buildings.
 Thus, communication requirements
for HAN applications are low power
consumption, low cost, simplicity,
and secure communication.

 A NAN is the logical representation of an Advanced Metering Infrastructure
(AMI) system that connects customer premises with the utility control center.
 The basic constituent of an NAN/AMI network is the smart meter that performs a
variety of intelligent metering tasks.

 Each of these Smart Grid applications
deploys thousands of network devices that
need to be managed continuously for reliable
operations.
 Unfortunately, the management of this
massive infrastructure requires additional
labor and cost for the utility companies who
own these networks.
 One sustainable solution to this network
management problem is the use of the
emerging SDN,
 SDN can provide excellent opportunities for
reducing the network management cost by
integrating a software-based control that can
be ﬂexible with respect to software
upgrades, ﬂow-control, security patching,
and quality of service (QoS)

 SDN seems to be a promising solution for the aforementioned problems due to following
advantages:
 SDN provides a global end-to-end view of the network which make the large scale
management more effective.
 SDN adopts open standards to configuring and maintaining various types of network
elements that are common in Smart Grid.
 Hardware virtualization through SDN eases the burden of managing different networks
while using resources efficiently.
 Due to its holistic view of network, the SDN-based network will provide superior control
of delay and jitter in the network.
 SDN’s bandwidth-on-demand capabilities will also create opportunities to increase
revenue through accelerated service velocity.
