Executive Summary

In traditional network management, network topology is one of the key parameters that needs to be known in order to perform operations like performance management, fault detection and isolation, and capacity planning. Large displays showing the network topology are common sights in Network Operation Centers (NOC). In the Internet, despite the fact that the control and ownership are highly distributed, researchers have also attempted to gain understanding of the Internet topology. In wireless sensor network, in addition to tackling traditional network issues such as fault monitoring/debugging and root-cause analysis, connectivity information also helps in ways that are unique to how sensor network operates.
