IEEE 802.11ah ialah spesifikasi yang dibangunkan untuk operasi dikecualikan lesen sub-1GHz dan bertujuan untuk menyediakan perkhidmatan komunikasi Kawasan Luas Kuasa Rendah (LPWA) dan menyokong ciri Internet Perkara (IoT) seperti rangkaian berskala besar dan julat penghantaran lanjutan. Walau bagaimanapun, ciri ini juga menjadikan rangkaian 802.11ah sangat terdedah kepada pertikaian saluran dan masalah nod tersembunyi (HNP). Untuk menangani masalah tersebut, Kumpulan Petugas 11ah mencadangkan mekanisme Tetingkap Akses Terhad (RAW). Ia menunjukkan prestasi cemerlang dalam mengurangkan perbalahan saluran, tetapi kesannya terhadap penyelesaian HNP adalah tidak memuaskan. Dalam makalah ini, kami mencadangkan algoritma pengelompokan nod tersembunyi (HNGA) yang mudah dan berkesan berdasarkan IEEE 802.11ah RAW. Algoritma mengumpul maklumat nod tersembunyi dengan mengambil kesempatan daripada proses perkaitan 802.11 dan kemudian melakukan pengelompokan seragam dua peringkat untuk mengelakkan perlanggaran nod tersembunyi (HNC). Prestasi algoritma yang dicadangkan dinilai berbanding dengan skema sedia ada lain dalam situasi nod tersembunyi. Keputusan menunjukkan bahawa algoritma yang dicadangkan kami menghapuskan kebanyakan pasangan nod tersembunyi di dalam kumpulan RAW dengan penalti overhed yang rendah, dengan itu meningkatkan prestasi rangkaian. Selain itu, algoritma itu kebal terhadap HNC yang disebabkan oleh penghantaran sempadan slot silang.

Abstract: IEEE 802.11ah is a specification being developed for sub-1GHz license-exempt operation and is intended to provide Low Power Wide Area (LPWA) communication services and support Internet of Things (IoT) features such as large-scale networks and extended transmission range. However, these features also make the 802.11ah networks highly susceptible to channel contention and hidden node problem (HNP). To address the problems, the 11ah Task Group proposed a Restricted Access Window (RAW) mechanism. It shows outstanding performance in alleviating channel contention, but its effect on solving HNP is unsatisfactory. In this paper, we propose a simple and effective hidden node grouping algorithm (HNGA) based on IEEE 802.11ah RAW. The algorithm collects hidden node information by taking advantage of the 802.11 association process and then performs two-stage uniform grouping to prevent hidden node collisions (HNCs). Performance of the proposed algorithm is evaluated in comparison with other existing schemes in a hidden node situation. The results show that our proposed algorithm eliminates most of hidden node pairs inside a RAW group with low overhead penalty, thereby improving the performance of the network. Moreover, the algorithm is immune to HNCs caused by cross slot boundary transmissions.
