Enabling Energy Efficient Sensory Data Collection with Mobile Sink
Now-a-days the usages of wireless sensor networks will get rapidly increased. A large class of Wireless Sensor Networks (WSN) applications involves a set of isolated urban areas (e.g. building blocks) covered by Sensor Nodes (SNs) monitoring environmental parameters. Mobile Sinks (MSs) mounted upon urban vehicles with fixed paths provide the ideal infrastructure to effectively retrieve sensory data from such isolated WSN fields. Existing methodologies 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, handling, buffering, and delivering tasks.
