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
