This document discusses using software defined networks (SDN) for smart grid communication. It begins with an introduction to SDNs and smart grids. It then describes the different communication networks that make up a smart grid: home area networks (HAN), neighborhood area networks (NAN), and wide area networks (WAN). SDNs are presented as a promising solution for managing the large number of devices in smart grids by providing a global view of the network and using open standards to configure elements. Adopting SDNs could reduce management costs for utilities and provide superior network control and bandwidth-on-demand capabilities for smart grids.

 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.
