ABSTRACT
Wireless backhaul has received much attention as an enabler of future broadband mobilecommunication systems because it can reduce deployment cost of pico-cells, an essential part ofhigh capacity system. A high throughput with a minimum delay network is highly appreciated tosustain the increasing proliferation in multimedia transmissions. In this paper, we propose abackhaul network using the Multi-Input Multi-Output (MIMO) IEEE 802.11n standard inconjunction with the Dual Channel Intermittent Periodic Transmit IPT (DCH-IPT) packetsforwarding protocol. By using these two techniques (IEEE 802.11n + DCH-IPT), wirelessbackhaul nodes can meet more demanding communication requirements such as higherthroughput, lower average delay, and lower packet dropping rate than those achieved by thecurrently used backhaul. The current backhaul is based upon Single-Input Single-Output (SISO)IEEE 802.11a,b,g standards in conjunction with Single Channel Conventional (SCH-Conv)relaying protocol in which packets are transmitted continuously from source nodes using singlechannel. The proposed backhaul will accelerate introduction of picocell based mobilecommunication systems.
