IEEE 802.11n based wireless backhaul enabled by Dual Channel IPT (DCH-IPT) relaying protocol

Wireless backhaul has received much attention as an enabler of future broadband mobile communication systems because it can reduce deployment cost of pico-cells, an essential part of high capacity system. A high throughput with a minimum delay network is highly appreciated to sustain the increasing proliferation in multimedia transmissions. In this research, we propose a backhaul network using the IEEE 802.11n standard in conjunction with the Dual Channel Intermittent Periodic Transmit IPT (DCH-IPT) packets forwarding protocol. By using these two techniques (IEEE 802.11n + DCH-IPT), wireless backhaul nodes can meet more demanding communication requirements such as higher throughput, lower average delay, and lower packet dropping rate than those achieved by adopting IEEE 802.11n to Dual Channel conventionally (DCH-Conv) relayed backhaul, in which packets are transmitted continuously from source nodes, which will accelerate introduction of picocell based mobile communication systems.
