Abstract
Energy conservation is one of the most basic problems of wireless sensor networks. Energy of sensor nodes is limited, so effective energy usage is important. Data aggregation helps to minimise the volume of data communicated across the network while preserving information quality and decreasing energy waste, thereby enhancing the lifetime of network. In this paper, we propose a data aggregation approach based on the important extrema points extraction for elongating the WSN lifetime (IEEDA). Rather than transmitting all the set of collected measures at the end of every time period, we propose transmitting the extracted important extrema measures of sensor node. Using real-world data sets with radically different properties, we tested our method against two protocols ATP and PFF. The proposed method resulted in a reduction in the amount of the following: data remaining up to 95%, data sent up to 80%, and energy consumed up to 77%.
