在自组织网络中，洪泛被用来将消息传递到整个网络。然而，泛洪的过度使用会产生大量的冗余分组，并给网络带来沉重的流量负载。为了解决这一问题，人们提出了许多方案。但由于这些研究没有考虑到影响网络效率的每个节点的实际负载情况，所以没有太多的研究能够同时实现高报文可达性和减少冗余重播。在本文中，我们提出了两种新的负载感知洪泛方法，通过观察每个节点上的MAC传输队列来决定是否发送重播消息。通过网络仿真，对该方案的有效性进行了评估和验证。
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.
