mobile Adhock network

1. Manet -:Presented By:-KaushikParmar

2. Introduction Importance of computer networks Solutions to wireless approach Birth of MANET Ad hoc network

3. Ad hoc network A LAN or other small network A communication network without a pre-exist network infrastructure Role of Radio Terminals (RT)

4. Characteristics Communication via wireless means Nodes are the hosts and routers No centralized controller and infrastructure Dynamic network topology Autonomous

5. Application areas Military or police exercises Disaster relief operations Mine site operations Urgent Business meetings Robot data acquisition

6. Manet Collection of independent mobile nodes Fully distributed network Makes it highly flexible and robust Kind of wireless ad hoc network A type of mesh network

7. Types Of Manets Vehicular Ad Hoc Networks (VANETs) Intelligent vehicular ad hoc networks (InVANETs) Internet Based Mobile Ad hoc Networks (iMANET)

8. Network Security Computer security + secure communication Variables considered:- Environmental concerns Range of the network Quality of service Security criticality

9. Security in Manet Much more vulnerable to attack than wired network Dynamically Changing Network Topology Cooperative Algorithms Lack of Centralized Monitoring Lack of Clear Line of Defense

10. Pros Access to information and services regardless of geographic position Can be set up at any place and time Work without any pre-existing infrastructure

11. Cons Limited resources Limited physical security Lack of authorization facilities Security protocols for wired networks cannot work for ad hoc networks

12. Conclusion
