Design and evaluation of the performance-degradation estimation method at a wireless network

Abstract (in Japanese) (See Japanese page) 
(in English) In the wireless network based on IEEE802.11, the troubleshooting by the system administrator is very difficult because the scheme that estimates the main cause of the performance-degradation due to the congestion and shadowing, etc. cannot be established yet. To achieve the high reliability of wireless system, it is important to detect the performance-degradation as soon as it occurs, estimate the main cause, and recover it. In this paper, we focused the statistical fluctuation trend that appeared according to the cause and we have designed the statistical analysis scheme which can detect the performance-degradation at a wireless network and estimate the main cause. Through the experimentation which emulates the congestion and shadowing environment, the feasibility of this scheme has been confirmed.
