Intermittent Periodic Transmit (IPT forwarding) is known as a packet forwarding scheme that achieves highly efficient packet relays in wireless multihop networks. This paper proposes a path reservation technique to enable the IPT forwarding in any network topologies. The proposed scheme can be combined with a conventional routing algorithm such as tree type ones or mesh type ones. Simulation results ensure that the combination of the IPT forwarding with the proposed path reservation achieves higher throughput and lower average packet delay compared with a conventional packet forwarding method.
