In recent years, Wireless Mesh Networks (WMNs) have emerged as a promising solution to provide low cost networks that extend Internet access and other networking services. Mesh routers form the backbone connectivity through cooperative routing in an often unstable wireless medium. Therefore, the techniques used to monitor and manage the performance metrics to help optimize the link performance in WMNs. This paper presents an assessment of the correlation between passive monitoring and active probing techniques used for link performance measurement in WMNs. This paper presents an assessment of the correlation between passive monitoring and active probing techniques used for link performance measurement in WMNs. The study reveals that by combining multiple performance metrics obtained by using passive monitoring, a good correlation with active probing can be achieved. We then analyze the reaction of the passive monitoring and active probing techniques to variations in the network load. This study shows that these two performance measurement techniques can be used interchangeably.
