Rehan Ahmad, Javaid Rashid, Suhail Iqbal, Khurshid Asghar · 2014
The aim of this research is to measure the performance of multi-channel wireless network using throughput and response time performance metrics with antenna separation, transmit power, TCP windows size, and UDP buffer size/datagram and frequency channel scheme factors. The main purpose to study the multi-channel wireless networks is to increase the bandwidth. In our research we have characterized the performance of multi-channel wireless networks consisting of IEEE 802.11b or IEEE 802.11g devices. We have conducted experiments on a simple topology consisting of two access points having same or non-overlapping frequency channels. Research study shows the effect of change in frequency channels, change in transmission power, and change in TCP windows size or UDP datagram size on performance. The results of this study are important contribution when configuring a multi-channel wireless network with non-overlapping frequency channels.
