Rangkaian wayarles di mana-mana kawasan luas, yang terdiri daripada pusat akses (AP) yang disambungkan ke rangkaian tetap dan banyak terminal wayarles (WT), boleh menawarkan pelbagai aplikasi di mana-mana sahaja. Untuk meningkatkan prestasi rangkaian, kami perlu mengumpul pelbagai jenis data daripada seberapa banyak WT yang mungkin; setiap AP mesti mampu menampung lebih daripada 103 WTs. Keperluan ini boleh dicapai dengan menggunakan DSA, skim kawalan capaian media terpusat biasa, kerana ia mempunyai kecekapan penggunaan sumber yang tinggi. Dalam kertas kerja ini, kami mencadangkan skim DSA baru yang menggunakan tiga teknik baharu untuk meningkatkan prestasi daya pengeluaran; (1) memandangkan kebanyakan terminal cenderung untuk menghantar data secara berkala, ia menggunakan kedua-dua skim berasaskan pengundian, iaitu undian permintaan dan pengundian data, dan skim akses rawak. (2) Untuk meningkatkan keberkesanan penggunaan lebar jalur melalui pengundian, masa pengundian diputuskan mengikut masa penjanaan data. (3) AP memutuskan saiz data yang ditinjau mengikut pengedaran saiz data terkini dan meninjau WT untuk data secara langsung. Jika saiz undian data tidak dapat ditentukan dengan yakin, AP menggunakan tinjauan permintaan dan bukannya tinjauan data. Simulasi mengesahkan bahawa skim yang dicadangkan menawarkan prestasi penghantaran yang lebih baik daripada skim sedia ada.

Abstract: Wide area ubiquitous wireless networks, which consist of access points (APs) connected to the fixed network and a great many wireless terminals (WTs), can offer a wide range of applications everywhere. In order to enhance network performance, we need to collect different kinds of data from as many WTs as possible; each AP must be capable of accommodating more than 103 WTs. This requirement can be achieved by employing DSA, a typical centralized media access control scheme, since it has high resource utilization efficiency. In this paper, we propose a novel DSA scheme that employs three new techniques to enhance throughput performance; (1) considering that most terminals tend to send data periodically, it employs both polling-based schemes, i.e. request-polling and data-polling, and a random access scheme. (2) In order to enhance bandwidth utilization effectiveness by polling, the polling timing is decided according to the data generation timing. (3) The AP decides the polled data size according to the latest distribution of data size and polls the WT for the data directly. If the data-polling size can not be determined with confidence, the AP uses request-polling instead of data-polling. Simulations verify that the proposed scheme offers better transmission performance than the existing schemes.
