In this paper, Meeting Position Aware Routing (MPAR) is proposed for query-based mobile enabled Wireless Sensor Network (mWSN). The authors consider mWSNs with dense sensor nodes deployed in the sensing field. A Mobile Sink (MS) moving through the sensing field with random speed queries a specific area or a point of interest for information from physical world. Queried data over a area is aggregated to a source node and delivered to the mobile sink via multi-hop communication. The feature of MPAR is that the mWSNs can predict the position of the mobile sink at the time it meets the data packet. The queried data packet is delivered towards this predicted position from the source node during the propagation.
