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.
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.
- 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.
- 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.
- Symmetric Environment : As all the nodes are similar in functionality and can act either as node or a router resulting in a symmetric environment.
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:
- High Power Consumption.
- Cost Efficient.
- Infrastructure less.
- Autonomous Network.
- No Need of separate Routers – Each node can work as router too.
- Network Topology – Not defined.
MANET(Mobile Ad-Hoc Networks) : Disadvantages
Some of the disadvantages of MANET are:
- High power consumption.
- Low in range of connectivity.
- Less secure-More prone to attacks.
- Computational power-Limited.
- Lower transmission speeds as compared to fixed networks.
