Energy-Efficient Data Collection with Mobile Sinks Using Wireless Sensor Socors Destination (SD) Technique
The Wireless Sensor Networks (WSN) applications involve a set of isolated urban areas covered by Sensor Nodes (SNs) monitoring environmental parameters. Mobile Sinks (MSs) mounted upon urban vehicles with fixed trajectories (e.g., buses) provide the ideal infrastructure to effectively retrieve sensory data from such isolated WSN fields. Existing approaches involve either single-hop transfer of data from SNs that lie within the MS's range or heavy involvement of network periphery nodes in data retrieval, processing, buffering, and delivering tasks.
