Terdapat banyak minat dalam pertanyaan spatial yang memperoleh bacaan penderia daripada nod penderia di dalam kawasan geografi yang diminati. Pendekatan berpusat melaksanakan pertanyaan spatial pada pelayan selepas memperoleh semua bacaan sensor. Walau bagaimanapun, ia menanggung kos penghantaran wayarles yang tinggi dalam mengakses semua nod sensor. Oleh itu, pelbagai kaedah carian spatial dalam rangkaian telah dicadangkan, yang memberi tumpuan kepada mengurangkan kos penghantaran tanpa wayar. Walau bagaimanapun, kaedah dalam rangkaian kadangkala menimbulkan penghantaran tanpa wayar yang tidak diperlukan kerana ruang mati, yang diindeks secara spatial tetapi tidak mengandungi data sebenar. Dalam kertas ini, kami mencadangkan algoritma pemprosesan pertanyaan spatial hibrid yang mengalih keluar penghantaran wayarles yang tidak diperlukan. Idea utama algoritma hibrid adalah untuk mencari hasil pertanyaan spatial pada pelayan terlebih dahulu dan menggunakan hasilnya dalam mengalih keluar penghantaran wayarles yang tidak diperlukan pada rangkaian sensor. Kami membandingkan kaedah dalam rangkaian melalui beberapa percubaan dan menjelaskan ciri-ciri luar biasa algoritma kami.

Abstract: There has been much interest in a spatial query which acquires sensor readings from sensor nodes inside specified geographical area of interests. A centralized approach performs the spatial query at a server after acquiring all sensor readings. However, it incurs high wireless transmission cost in accessing all sensor nodes. Therefore, various in-network spatial search methods have been proposed, which focus on reducing the wireless transmission cost. However, the in-network methods sometimes incur unnecessary wireless transmissions because of dead space, which is spatially indexed but does not contain real data. In this paper, we propose a hybrid spatial query processing algorithm which removes the unnecessary wireless transmissions. The main idea of the hybrid algorithm is to find results of a spatial query at a server in advance and use the results in removing the unnecessary wireless transmissions at a sensor network. We compare the in-network method through several experiments and clarify our algorithm's remarkable features.

AB - There has been much interest in a spatial query which acquires sensor readings from sensor nodes inside specified geographical area of interests. A centralized approach performs the spatial query at a server after acquiring all sensor readings. However, it incurs high wireless transmission cost in accessing all sensor nodes. Therefore, various in-network spatial search methods have been proposed, which focus on reducing the wireless transmission cost. However, the in-network methods sometimes incur unnecessary wireless transmissions because of dead space, which is spatially indexed but does not contain real data. In this paper, we propose a hybrid spatial query processing algorithm which removes the unnecessary wireless transmissions. The main idea of the hybrid algorithm is to find results of a spatial query at a server in advance and use the results in removing the unnecessary wireless transmissions at a sensor network.
