One of the key mechanisms underlying a Wireless Sensor Network (WSN) is to monitor the network itself. Many existing approaches perform centralized analysis and maintenance based on a large amount of status reports collected from the WSN, while others use add-on protocols/modules that not only require extra management cost but also interrupt the normal operations of targeted WSN applications. Unlike existing work, the authors propose LoMoM, a new approach of Local Monitoring and Maintenance for a WSN, which combines monitoring operations for the WSN with the operations of a mobile event monitoring, in a manner that is both energy- and latency-efficient.
