DEFINATION OF NETWORKING
4
Network:
• A system consisting of many similar parts that are connected to allow
movement or communication between or along the parts.
Computer Network:
• Several computers that are connected so that they can share information.

NETWORK INFRASTRUCTURES
6
• Wired network infrastructure consists of some wiring
and networking devices such as switches and routers
• Wireless network infrastructure consists of the
location and capacity assignments of base stations,
Wi-Fi points, modems, and/or repeaters

• Unfortunately, establishing a new
infrastructure is sometimes impossible or
not cost-efficient, like military operations,
dangerous environment conditions,
natural disasters.

AD HOC NETWORK USES
8
• Instead of a preset infrastructure, ad hoc
network is a self-configuring and self-
coordinated dynamic network.
• Each node can behave as a source or a
destination or a relay.
(MANET)

• In a military operation, the wireless nodes can establish an ad hoc network to
communicate each other.

TYPES OF AD HOC NETWORK

&
• Ad Hoc Networks can have very different design objectives based on their usage area. So,
they may have different names; MANET, VANET, Sensor Networks etc.

FLYING AD HOC NETWORK - FANET

&
• We proposed a new type of ad hoc network as FANET, where the nodes are UAVs.

ADVANTAGES OF UAVs

&
• UAVs are getting smaller and cheaper. The advantages of the multi-UAV
systems are
• Cost
• Scalability
• Survivability
• Speed-up
• Small radar cross-section.
• Coordination and collaboration of multiple UAVs can create a system that is
beyond the capability of only one UAV.

CONCLUSION

FANETs have become an emerging research field, which consists of a group of small UAVs
connected in ad-hoc mode. Such networks are distinguished by a high mobility, frequent topology
changes and 3D-space movement of the nodes, which constitutes networking issues. To overcome
such kind of issues, choosing an appropriate communication architecture and reliable routing
protocols are mandatory to authenticate robust communication between the UAVs.
In this paper, we first introduced three different decentralized communication architectures, in which
we proposed a multi-layer UAV ad hoc network more suitable for FANETs. Subsequently, we
investigated various routing protocols along with open research issues. We hope this investigation
will help network engineers for FANETs deployment. We also believe that FANETs will be ubiquitous
technology in the future.
