Abstract :
In ad hoc networks, the flooding is used to deliver message to the whole network. However, excessive use of flooding generates a large number of redundant packets, and it gives heavy traffic load to the network. To solve this problem, many schemes have been proposed. But since those studies do not take into account the actual load condition of each node that will affect network efficiency, not so many studies achieve both performing the high message reachability and reducing redundant rebroadcast. In this paper, we propose two novel load-aware flooding methods observing the MAC transmission queue on each node to make the decision about whether rebroadcast messages should be sent or not. Through the network simulation, we evaluate and show the effectiveness of our proposal.
