What is Sensor Network Tomography: monitoring wireless sensor networks about?

Wireless sensor networks have been attracting increasing research interest given the recent advances in miniaturization and low-cost, low-power design. Consisting of a large collection of small wireless, low-power, unattended sensors and/or actuators, wireless sensor network technology poses its unique design challenges. Given their unattended nature and their complexity, it is critical that the users be given continuously updated indications of the sensor network __health,__ i.e., explicit knowledge of the overall state of the sensor network after deployment. We call such indications of network health __scans.__ Such macroscopic view of resources or activities in large sensor networks can provide users early warning of system failure, aid in incremental deployment of sensors, or tuning sensor collaboration algorithms.Monitoring wireless sensor networks leads to different challenges compared to existing diagnosis protocols for the Internet, or monitoring systems in other domains such as telecommunication networks, or power generation systems. The monitoring system should introduce minimal impact on network lifetime, scale with network size, yet preserve the __fidelity__ of the over
