Abstract
In ad hoc networks, flooding is used to deliver messages to the whole network. To reduce redundant packets and traffic load, many methods 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 many studies achieve both ensuring the high message reachability and reducing redundant rebroadcast. We have proposed novel methods using the MAC transmission queue of each node to make the decision about whether rebroadcast messages should be sent or not. In this paper, we focus on the Load-aware Dynamic Probabilistic Flooding (LDPF), which determines the rebroadcast probability dynamically based on MAC transmission queue information. Through a network simulation, we evaluate and show the effectiveness of our proposal.
