Signal Interference of Ubiquitous Wireless Networks on Data Throughput

초록

Ubiquitous wireless networks consist of many wireless access points and devices, which share and contend for wireless medium. Generally, wireless devices are trying to generate high throughput and have longer signal coverage which also bring unnecessary signal interference to neighboring wireless networks, and result in decreased network throughput. Signal interference is an inevitable problem because of the broadcast nature of wireless transmission. However it could be minimized by reducing signal coverage of wireless devices. On the other hand, small signal coverage means low transmission power and low data throughput. In the paper, we analyze the relationship among signal strength, coverage, interference and network throughput in ubiquitous wireless networks by simulation on various network topologies.
