Introduction
Broadcasting in the field of network communication usually means the distribution of messages/data to a number of recipients.
Why broadcasting?
Broadcasting is a common technique to realize many network issues such as
- paging,
- sending alarm signals,
- routing (e.g., DSR, ZRP, AODV),
- providing multicast in rapidly changing topologies.
Broadcasting by flooding
There are several ways to send a message from one host to all the other hosts. Broadcasting done by flooding is a simple and straight-forward approach to deal with this problem.
Remember: In MANETs we're usually confronted with a multihop scenario!
