However, continuous transmission of the sensed data requires high energy consumption. Data transmission between sensor nodes and cluster heads (sink nodes) consumes much higher energy than data sensing in WSNs. One way of reducing such energy consumption is to minimise the number of data transmissions. In this paper, we propose an Adaptive Method for Data Reduction (AM-DR). Our method is based on a convex combination of two decoupled Least-Mean-Square (LMS) windowed filters with differing sizes for estimating the next measured values both at the source and the sink node such that sensor nodes have to transmit only their immediate sensed values that deviate significantly (with a pre-defined threshold) from the predicted values. The conducted experiments on a real-world data show that our approach has been able to achieve up to 95% communication reduction while retaining a high accuracy (i.e. predicted values have a deviation of ±0.5 from real data values). date: 2018-05-07 date_type: published publisher: IEEE official_url: https://doi.org/10.1109/WF-IoT.2018.8355187 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1578641 doi: 10.1109/WF-IoT.2018.8355187 isbn_13: 9781467399449 lyricists_name: Fathy, Yasmin lyricists_id: YABBA16 actors_name: Fathy Abbas, Yasmin Abbas actors_id: YABBA16 actors_role: owner full_text_status: public series: World Forum on Internet of Things publication: IEEE World Forum on Internet of Things, WF-IoT 2018 - Proceedings volume: 4 pagerange: 729-735 event_title: 2018 IEEE 4th World Forum on Internet of Things (WF-IoT), 5-8 February 2018, Singapore book_title: 2018 IEEE 4th World Forum on Internet of Things (WF-IoT) citation: Fathy, Y; Barnaghi, P; Tafazolli, R; (2018) An adaptive method for data reduction in the Internet of Things.
