Measurement of Interference in WIFI Networks by Co-ordinated Sampling of Network Monitoring
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 4
Abstract
We present an approach to estimate the interference between nodes and links in a live wireless network by passive monitoring. This does not require any access to the network nodes. Our approach requires deploying multiple sniffers across the network to capture wireless traffic traces among multiple channels. IEEE 802.11 networks support multiple channels, and a wireless interface can monitor only a single channel at one time. Thus, capturing all frames passing an interface on all channels is an impossible task, and we need strategies to capture the most representative sample. When a large area is to be monitored, several sniffers must be deployed, and these will typically overlap in their area of coverage. The goals of effective wireless monitoring are to capture as many frames as possible, while minimizing the number of those frames that are captured redundantly by more than one sniffer. The above goals may be addressed with a coordinated sampling strategy that directs neighboring sniffer to different channels during any period. The probability of deferral is estimated using the hidden markov model from the captured traffic traces.This coupled with probability of collision to conclude the interference in wifi networks.
