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!
