Design and Analysis of Intelligent Sink for the Information Retrieval in Sensor Networks

This paper introduces an intelligent sink mechanism based on the observation and analysis of non-uniform energy consumption problem in sensor network, in which more energy consumed at nodes near the sink than at nodes far away. The proposed intelligent sink utilizes dynamic sink proxies for localized data query and collection, so as to achieve highly distributed and low energy consumption among sensor nodes. The evaluation result reveals that the proposed sink mechanism reduces the energy consumption of information retrieval in the network and obtains balanced energy consumption among sensor nodes.
