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.
