MobiCom 2010 Poster: Passive Online Wireless LAN Health Monitoring From a Single Measurement Point

Free registration required

Executive Summary

Wireless LANs that are deployed in corporations and university campuses can contain a large number of access points and wireless hosts. In this paper, the authors develop a scalable approach that relies on measurements collected by a single monitor for WLAN health monitoring. They propose two metrics, local RTT and local loss rate that indicate whether a wireless host experiences performance degradations inside a WLAN, and both can be obtained from measurements at the single monitor. Preliminary evaluation through data collected by a monitor at a university gateway router demonstrates the effectiveness of these two metrics.
