Abstract

This paper introduces the usage and selection of spatial-temporal sink proxy for on-demand information retrieval in sensor networks. A sink proxy is a sensor node selected among sensor nodes by the sink node for local query distribution and data collection. Such a sink node, termed the intelligent sink, utilizes the correlation of query content and individual sensor nodes to specify the corresponding sensor nodes of user interest, and then selects the sink proxy according to the locations of sensor nodes. The proposed scheme achieves highly distributed and low energy consumption among sensor nodes. The evaluation results reveal that the proposed sink-proxy scheme reduces the energy consumption of information retrieval in the network and obtains balanced energy consumption among sensor nodes.

Keywords: Sensor networks information retrieval intelligent sink sink proxy
