%X To reduce the broadcast storm of PREQ caused by simply flooding of PREQ to maintain routes between leaf nodes in tree network based on IEEE 802. 11s, this paper proposed a new scheme to limit the broadcast region of PREQ based on the table-driven routing in HWMP. In this scheme, one leaf node set the TTL of PREQ according to the hop count in its route to the root node, which limited the delivery distance of PREQ and decreased the number of redundant PREQ. Experiment shows that compared with IEEE 802. 11s, this new scheme can effectively reduce the costs for routing and increase the network throughput.
