 Software-defined networking (SDN) is an umbrella term
encompassing several kinds of network technology aimed
at making the network as agile and flexible as the
virtualized server and storage infrastructure of the modern
data center.
 software defined networking (SDN) paradigm promises to
simplify network configuration and resource management
dramatically.
Software Define Wireless Network

 A centralized approach to network control:
centralized approach to network control raises crucial
problems about which network element(s) should run
network control operations but makes network optimization
easier.
 Energy consumption
problem

 SDWN must support duty cycles:
The most obvious way to reduce the energy consumption is turning the
radio off when it is not utilized, that is, using duty cycles.
 SDWN must support in-network data aggregation :
Energy consumption can be reduced by removing
the redundancy from the data circulating in the network,
that is, by using data aggregation techniques.

 Mobile wireless sensor networks (MWSNs) can be defined
as a wireless sensor network (WSN) in which sensor nodes
are mobile. MWSNs are an emerging field of research in
contrast to their well establish predecessor.
 MWSNs are much more versatile than static sensor
networks as they can be deployed in any scenario and cope
with rapid topology changes.
 Advantages over static wireless network:
1. better energy efficiency 2- improved coverage 3-
enhanced target tracking 4- superior channel capacity .

 A wireless ad hoc network (WANET) is a decentralized
type of wireless network. The network is ad hoc because
it does not rely on a pre existing infrastructure, such as
routers in wired networks or access points in managed
(infrastructure) wireless networks.
 Wireless Ad hoc networks are networks in which communication
links are based on wireless technologies and the network structure
or topology is not pre-defined rather build through dynamic
network connectivity.
 Relation with other ad hoc networks:
WANET ⊃ WSN , ⊃ (MANETS ⊃ VANETS)
WANET

 A Mobile Ad-hoc network is a wireless ad-hoc network which is used to exchange
informtion. A Mobile Ad-hoc network is a wireless ad-hoc network which is used to
exchange information .
 Mobile Ad Hoc Network is basically a combination of wireless network having no fixed
nodes and not a fixed infrastructure. In MANETs, devices can move freely. Nodes within
the range of other wireless devices make a virtual infrastructure. Furthermore; there is
also not a centralized body to control the communications between nodes.
 Form by wireless hosts, which may be mobile. No infrastructure required for the
connection. Nodes between hops may continuously contain multiple hops. Nodes acts as
routers to forward packets for each other and nodes keep changing the routes
 In mobile Ad Hoc Network, nodes connected to each other without any physical
connection e.g. coaxial cables or fiber optics cable. All of these are wireless devices and
their position is not fixed. They move from one point to another and if any one of them
moved away from the range of other nodes then communication between them will also
be dropped.

MANETS

 On wireless computer networks, ad-hoc mode is a method
for wireless devices to directly communicate with each
other. Operating in ad-hoc mode allows all wireless devices
within range of each other to discover and communicate in
peer-to-peer fashion without involving central access
points (including those built in to broadband wireless
routers).
 To set up an ad-hoc wireless network, each
wireless adapter must be configured for ad-hoc mode
versus the alternative infrastructure mode.
What is Ad-Hoc Mode in Wireless Networking?

 Applications:
 It is use in military environment such as when there is any war
for soldiers to contact with each other MANET is used
 Use in civilian environments like in vehicle networks,
conferences/stadiums, outside activities etc
 It is use in emergency situations like in search-and-rescue
operations , in policing and fire fighting etc.
MANETS

 In 2005, northern areas of Pakistan were destructed by a
massive attack of earth quake and all the ways of
communication had been disconnected. This is only one example
of breakdown of communication in Pakistan. The same disasters
are occurring all around the world in different forms such as
Tornados, Hurricanes and earth quakes and so on. The main
issue is that after having these disastrous attacks, one really
needs to communicate the people of the affected areas as soon
as possible in order to know the amount of destruction and
about causalities over there. In that case, one really need a fast
way of communication which is more probable reliable and easy
to connect.
MANETS:case study

 In that case, we can put our trust on Ad -HOC mobile
network which is the only fastest way of communication
between different wireless nodes. In MANETs, the initial or
the source node pass on information to the next available
node and ask about the location of final node. The next
available node move on further information to very next
node available to it and ask about the final destination. The
information is passing on from one node to another back
and forth and in this way the source node knows the final
destination node location and hence finally communication
between two entities going on.

 This facilitates querying, monitoring, and tasking of sensor networks.
 serves the role of middleware that abstracts a network of sensor nodes
as a collection of massively distributed objects.
 ITS execution environment provides a set of configuration and
communication primitives that enable scalable and energy-efficient
organization of and interactions among sensor objects.
 On top the execution environment is a programmable substrate that
provides mechanisms to create associations and coordinate activities
among sensor nodes.
 Users then access information within a sensor network using
declarative queries, or perform tasks using programming script.

Middleware

 Information Abstraction:
A sensor network is conceptually viewed as a collection
of datasheets which are relational.
 Sensor Query and Tasking Language (SQLT):
SQTL plays the role of a programming interface between sensor
applications and the SINA middleware.
It is a procedural scripting language,designed to be
flexible and compact, with a capability to interpret
simple declarative query statements.
SI networks:SQLT

 Further capabilities:
1- sensor hardware access (e.g., getTemperature, turnOn)
2- Location aware (e.g., isNeighbor, getPosition)
3- communication primitives (e.g , tell , execute)
4-Events
 receive:
Events generated when a message is received by a sensor node
 every
Events triggered periodically by a timer
 Expire:
Events caused by the expiration of a timer
SI Network: SQLT

 A sensor execution environment (SEE), running on
each sensor node, is responsible for dispatching
incoming messages, examining all arrival SQTL
messages, and performing the appropriate operation
for each type of action specified in the messages.
