MANET (Mobile Ad-Hoc Networks):
- Mobile Ad-hoc networks (MANETs) are collections of mobile nodes dynamically establishing short lived networks in the absence of fixed infrastructure.
- Each mobile node is equipped with a wireless transmitter and a receiver with an appropriate antenna.
- Nodes in MANET are free to move and organize themselves in an arbitrary manner.These nodes are connected bye wireless links and acts as a routers for all other mobile nodes in the network.
- An Ad-hoc routing protocol is a standard that controls how mobile nodes decide which way to route packets better computing devices in a mobile ad-hoc network.
- In MANET, mobile nodes are not familiar with the topology of their network in the beginning;instead, they have to discover it.
- A new node may announce its presence and should listen for announcements broadcast by it neighbors.
- Each node learns about nodes nearby and how to reach the and may announce that it too can reach them.
