间歇周期发送（IPT转发）是一种高效的无线多跳网络数据包转发方法。在IPT转发中，源节点间歇性地发送数据包，中继节点接收到数据包后立即转发，该方案所获得的频率复用空间与给定的发送周期成正比，如果发送周期选择适当，可以消除相邻节点之间的干扰。迄今为止进行的IPT转发评估假设传输条件是理想的。然而，实际情况显然更为复杂。在本文中，我们开发了无线多跳节点的测试床，并研究了在一个大型建筑物的4层IPT转发的可行性。每个节点都配备了Ad-hoc模式的802.11b无线接口以及我们为这些实验开发的用于IPT转发的专有协议。
Intermittent periodic transmit (IPT forwarding) has been proposed as a highly efficient packet forwarding method for wireless multihop networks. With IPT forwarding, packets are intermittently transmitted by a source node and each relaying node forwards a relaying packet immediately after receiving it. The frequency reuse space attained by this scheme is proportional to the given transmit period and if the transmit period is adequately chosen, interference between adjoining nodes in transmission can be removed. The IPT forwarding evaluations conducted to date have assumed that the transmission conditions were ideal. However, actual conditions are clearly more complex. In this paper, we develop testbeds of wireless multihop node and study the feasibility of IPT forwarding in a large-scale building with 4 stories. Each node is equipped with 802.11b wireless interface in the Ad-Hoc mode and proprietary protocols for IPT forwarding that we developed for these experiments.
