MANET : Introduction

  • MANET stands for Mobile Ad-Hoc networks.
  • In this, mobile means a node which can travel in every possible direction and ad-hoc means something which is used for a special purpose on continuous basis.
  • So, MANET can be defined as the type of network which is capable of being formed anywhere and is auto configuring and does not require any structure.
  • MANET is an infrastructure less network and are very beneficial to use as they can replace expensive networks having a infrastructure easily .

  • They are the networks which can be categorized as the network which does not have any physical connections i.e. wireless.

 

MANET(Mobile Ad-Hoc Networks) : Features

  • Being an infrastructure network, MANET possesses a number of features which enables its users to use it more frequently. 


This image describes the various features of MANET.
Features of MANET

  1. Remote Areas Access : Remote area access gives great feature of establishing an infrastructure less network in areas where population is less dense. It enables to save a huge amount of cost of setting an infrastructure, as Mobile Ad-Hoc Networks can be used depending upon the pattern of communication.

  2. Infrastructure Can Be Made Instantly : As Mobile Ad-Hoc Networks does not depends on any physical links, at any point of time and of any type of requirement. Mobile ad-hoc network can be set up and used, because normal networks requires pre-planning but Mobile Ad-Hoc Networks does not.
  3. Large-Small Network : Another great feature of Mobile Ad-Hoc Networks is its ability of changing the size of network as per requirement i.e. any number of nodes can be attached and any number of nodes can be detached.
  4. Symmetric Environment : As all the nodes are similar in functionality and can act either as node or a router resulting in a symmetric environment.

  5. Disaster Relief Ability : Any infrastructure is prone to natural disasters and can completely destroy it. So in order to save the capital on infrastructure, Mobile Ad-Hoc Networks can be used in those areas which are highly prone to natural disasters leading to a great amount of effectiveness in cost saving.

 

MANET(Mobile Ad-Hoc Networks) : Advantages

  • Having a lot of features results in a lot of advantages too. These are:
    1. High Power Consumption.
    2. Cost Efficient.
    3. Infrastructure less.
    4. Autonomous Network.
    5. No Need of separate Routers – Each node can work as router too.
    6. Network Topology – Not defined.
 

MANET(Mobile Ad-Hoc Networks) : Disadvantages

  • Some of the disadvantages of MANET are:

    1. High power consumption.
    2. Low in range of connectivity.
    3. Less secure-More prone to attacks.
    4. Computational power-Limited.
    5. Lower transmission speeds as compared to fixed networks.
