Mobile Ad Hoc Networks
Types of Mobile Networks
• Infrastructure networks
• Infrastructureless networks
Infrastructure Networks
It is based on the cellular concept And It has good infrastructure .
In infrastructure network the mobile devices are communicate with the others through base stations connected to the fixed network infrastructure.
Infrastructureless Networks
In infrastructureless network the mobile wireless network is commonly known as mobile adhoc network (MANET).
A MANET is a collection of wireless nodes that can dynamically form a network to exchange information without using any pre-existing network infrastructure.
Characteristics of MANET
• Infrastructure-less or with minimum infrastructure support.
• Self-organizing and self-managing.
• Most or all of the nodes are mobile.
• Network topology changes dynamically.
• Wireless communication.
• Node is working as a host and a router.
• Multi-hop.
Applications of MANET
• Military battlefield.
• Commercial sector.
• Local level.
• Personal area network.
• Etc
• Military battlefield
-- adhoc networking would allow the
military to take advantage of common place network technology to maintain an information between the soldiers, vehicles and military information head quarters.
• Commercial sector
-- adhoc networking can be used in emergency or any commercial area (business).
Ex:
hip- to- ship adhoc mobile communication.
Personal area network (PAN)
-- adhoc network can be used to
transfer the short –message between
various mobile devices.
Ex:: wireless LAN.
• Benefits from MANET
• Communication cost becomes cheaper.
• Self Network extended.
• Low Cost for building a network.
• Resources sharing.
• Route Discovery in MANET
• Route Reply in MANET
• Data Delivery in MANET
• Route Error (RERR)
• MANET Challenges
• Research Issues
• x-cast routing algorithms.
• QOS supporting model.
• Security , Reliability , availability schemes.
• Internetworking mechanisms.
Conclusion
• Ad Hoc Networks must connect to the Internet
• Group of Mobile Nodes moving together - Network in Motion
