Mobile ad-hoc networks (MANETs) allow for content distribution, information dissemination, and file sharing between Bluetooth and WiFi devices in an enterprise network. MANETs form multicast tree topologies to disseminate data packets between nodes, with clusters of nodes creating a multicast tree structure. Mesh networks provide robust data services for mobile networks through dynamic autonomous topology segments as an inexpensive alternative to infrastructure-based cellular networks. Protocols like PUMA create mesh networks connecting MANET nodes with multiple paths between senders and receivers to improve packet delivery in mobile environments. MANETs also enable applications like remote imaging, messaging, and file transfers between devices like cameras and smartphones.

Mobile Ad-hoc Network (MANET)
Applications

Content Distribution and
Synchronization
• In an enterprise, there are a number of
Bluetooth-enabled mobile handheld
devices, PCs, laptops, and WiFi access-
points
• MANET used for content-distribution, PIM,
other information dissemination,
information fusion, and file sharing in the
enterprise

MANET nodes in multicast tree
topology
• Ddisseminate data packets and form a
multicasting network
• Clusters of the nodes used to give a
multicast tree topology in a MANET

Mesh Networking and Mobile Service
Provider Network
• Mesh-based mobile networks offer highly
dynamic autonomous topology segments
for the robust IP-compliant data services
within the mobile wireless
communication networks
• Inexpensive alternatives or improvement
to infrastructure-based cellular CDMA or
GSM mobile service provider

Mesh Network
• A multicast tree network differs from mesh
as it provides only a single path between a
sender and a receiver
• Mesh network many paths

MANETs and fixed infrastructure network

Protocol for unified multicasting through
announcements (PUMA)
• A protocol that builds a mesh that
connects MANET nodes with each other
• On the other mesh provides multiple
paths between sender and receiver
nodes

Needs for PUMA
• MANETs have nodes which may be
mobile and the wireless links are error-
prone
• Certain packets may not be delivered to
receivers through a multicast tree
topology
• PUMA which send packets from senders
to receivers through multiple paths may
thus have a greater packet delivery ratio

9. © Oxford University Press 2007. All rights reserved. 9
Needs for PUMA
• However, in benign conditions (low
mobility and traffic load which leads to
lesser collisions), sending packets is not
needed and is a waste
• In such situations PUMA is able to
reduce the redundancy
• PUMA adapts the amount of redundancy
in the network depending on need

Image Acquisition, Processing and
Distribution using MANET
• Number of imaging devices forming a
MANETlow cost digital still camera
with a wireless network interface,
Wireless WebCam, mobile device
connected to a digital still camera, mobile
phones, and pocket PCs equipped with
an image acquisition sensor

Applications of Image Acquisition using
MANET
• Remote viewfinder by security personals
in an office
• Remote processing on a computer for a
video stream from wireless WebCam and
other devices

Applications of Image Acquisition
using MANET
• Image file transfer
• Messaging and data transmission to
remote devices using 802.11b (Section
1.1.5)
• Remote controlling.

IPv6 Integration and Wireless Sensor
Networks
• IPv6 is a new generation Internet and is
used for Internet radio and real time
video over the Internet
• IPv6 can be integrated with MANET and
wireless sensor networks
• CDMA handsets and Apple iPhone are
the examples of integration of the mobile
phones with IPv4 and IPv6
