    Manet Manet Presentation Transcript

    • Manet
      -:Presented By:-KaushikParmar
    • Introduction
      Importance of computer networks
      Solutions to wireless approach
      Birth of MANET
      Ad hoc network
    • Ad hoc network
      A LAN or other small network
      A communication network without a pre-exist network infrastructure
      Role of Radio Terminals (RT)
    • Characteristics
      Communication via wireless means
      Nodes are the hosts and routers
      No centralized controller and infrastructure
      Dynamic network topology
      Autonomous
    • Application areas
      Military or police exercises
      Disaster relief operations
      Mine site operations
      Urgent Business meetings
      Robot data acquisition
    • 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
    • Types Of Manets
      Vehicular Ad Hoc Networks (VANETs)
      Intelligent vehicular ad hoc networks (InVANETs)
      Internet Based Mobile Ad hoc Networks (iMANET)
    • Network Security
      Computer security + secure communication
      Variables considered:-
      Environmental concerns
      Range of the network
      Quality of service
      Security criticality
    • 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
    • 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
    • Cons
      Limited resources
      Limited physical security
      Lack of authorization facilities
      Security protocols for wired networks cannot work for ad hoc networks
    • Conclusion
