Dalam rangkaian penderia, banyak kajian telah dicadangkan untuk memproses pengagregatan dalam rangkaian dengan cekap. Tidak seperti pertanyaan pengagregatan umum, pemprosesan pertanyaan latar langit membandingkan data berbilang dimensi untuk hasilnya. Oleh itu, adalah sangat sukar untuk memproses pertanyaan latar langit dalam rangkaian penderia. Adalah penting untuk menapis data yang tidak diperlukan untuk pemprosesan pertanyaan latar langit yang cekap tenaga. Pendekatan sedia ada menyingkirkan penghantaran data yang tidak perlu dengan menggunakan penapis ke seluruh penderia. Walau bagaimanapun, jangka hayat rangkaian dikurangkan disebabkan penggunaan tenaga untuk menghantar penapis. Dalam makalah ini, kami mencadangkan algoritma pemprosesan pertanyaan latar langit dalam rangkaian berasaskan penapisan untuk mengurangkan penggunaan tenaga dengan menghantar penapis. Algoritma kami mencipta jadual penapis latar langit (SFT) dalam proses pengumpulan data yang menghantar data daripada nod penderia ke stesen pangkalan dan menapis penghantaran data yang tidak perlu menggunakannya. Keputusan percubaan menunjukkan bahawa algoritma kami mengurangkan positif palsu sebanyak 53% dan meningkatkan jangka hayat rangkaian sebanyak 44% secara purata berbanding kaedah sedia ada.

Abstract: In sensor networks, many studies have been proposed to process in-network aggregation efficiently. Unlike general aggregation queries, skyline query processing compares multi-dimensional data for the result. Therefore, it is very difficult to process the skyline queries in sensor networks. It is important to filter unnecessary data for energy-efficient skyline query processing. Existing approaches get rid of unnecessary data transmission by deploying filters to whole sensors. However, network lifetime is reduced due to energy consumption for transmitting filters. In this paper, we propose a lazy filtering-based in-network skyline query processing algorithm to reduce energy consumption by transmitting filters. Our algorithm creates the skyline filter table (SFT) in the data gathering process which sends data from sensor nodes to the base station and filters out unnecessary data transmissions using it. The experimental results show that our algorithm reduces false positive by 53% and improves network lifetime by 44% on average over the existing method.
