Flooding method in ad-hoc network
First Claim
1. A method for flooding a route request packet that is received at a first node in a communication system constructed of at least three nodes including a source node that requests to establish a route and a destination node that receives the route request, the method comprising:
- determining one of a plurality of levels having different transmission periods using a strength of a received signal of a measured packet;
selecting a transmission start point at the determined level and determining whether a route request packet is re-received before the selected transmission start point; and
broadcasting the received packet at the selected transmission start point when the packet is not re-received.

Abstract
A method for flooding a route request packet that is received at a node in a communication system constructed of at least three nodes including a source node that requests to establish a route and a destination node that receives the route request. One of a plurality of levels having different transmission periods is determined using a strength of a received signal of a measured packet. A transmission start point is selected at the determined level, and it is determined whether a route request packet is re-received before the selected transmission start point. The received packet is broadcast at the selected transmission start point when the packet is not re-received. The transmission start point is randomly selected within the transmission period or at the level in consideration of the number of the connected nodes.
