Abstract:
In the smart-phone era, many WiFi devices around us need higher throughput and larger signal coverage which also generate unwanted signal interference among the devices. Signal interference is inevitable problem because of the broadcast nature of wireless transmissions. However, the interference could be minimized by reducing signal coverage of nearby wireless devices. But, smaller signal coverage means low transmission power and low data throughput. In the paper, we analyze the relationship among signal strength, coverage and interference of WiFi networks, and as a tradeoff between transmission power and data throughput, we propose a range-aware WiFi network scheme which controls transmission power according to locations and RSSI of WiFi devices. We analyze the efficiency of the proposed scheme by simulation.
