A Training Based Transmission Period Setting Protocol

We have proposed Intermittent Periodic Tra nsmission (IPT forwarding) as packet relay method for wireless backhaul. In IPT forwarding, a source node sends packets to a destination node with a certain time interval (IPT duration) so that signal interference between relay nodes that send packets simultaneously are reduced and frequency reuse is realized, which brings about an improvement of system through put. However, the optimum IPT duration setting for each node is a difficult problem which was not solved adequately paper, we propose a new training based duration setting protocol which employs some training packets to search optimum IPT durations for each node. also extend the proposed protocol for wireless backhauls applying antennas. The proposed protocol ated both with computer simulation experiments. Evaluation results show that the proposed protocol is not only very effective but also practical.
