Monitoring and troubleshooting a large wireless mesh network
presents several challenges. Diagnosis of problems related to wire-
less access in these networks requires a comprehensive set of met-
rics and network monitoring data. Collection and offloading of a
large amount of data is infeasible in a bandwidth constrained mesh
network. Additionally, the processing required to analyze data from
the entire network restricts the scalability of the system and impacts
the ability to perform real-time fault diagnosis. To this end, we
propose MeshMon, a network monitoring framework that includes
a multi-tiered method of data collection. MeshMon dynamically
controls the granularity of data collection based on observed events
in the network, thereby achieving significant bandwidth savings
and enabling real-time automated management. Our evaluation of
MeshMon on a real testbed shows that we can diagnose a majority
