Types of Network

MOBILE AD HOC NETWORK

Ad hoc is a Latin phrase which means "for this

purpose“

A MANET is a type of Ad-hoc network.

Does not require base station.

Mobile Ad hoc Networks are self configuring

networks. Use wireless connections to connect to various networks.

Typical “peer-to-peer” rather than “client-server”.

1.Autonomous terminal

2.Operating without a central

coordinator

3.Dynamic network topology

4.Distributed Operation

5.Multi-hop routing

Stand-alone MANETAfter one of the nodes is configured as a

gateway, the entire network is connected to an external network like Internet

May need to traverse multiple links to reach destination

Challenges in Securing MANETsChallenges in Securing MANETs

•Data packets received in one place of the network and replay them in another place•Attacker can attack the Routing Algorithm

Challenges in Securing MANETsChallenges in Securing MANETs

Most packets will be routed to the Attacker

The Attacker can drop packets or forward packets to avoid detection

Advantages of MANETThis can be developed where there is less

telecommunication infrastructure

Cost Estimation is very less

These networks can be set up at any place and

time.

MANET is Multi-hop network with Autonomous

Terminal and dynamic network topology.

MANET can be used as Temporary Network

It requires less time

Personal area networking

Military environments

Disaster Area such as War-Zone and Natural

Calamity

Civilian environments

Emergency operations

VANET(Vehicular ad hoc Network)
