고정 네트워크에 연결된 액세스 포인트(AP)와 수많은 무선 단말기(WT)로 구성된 광역 유비쿼터스 무선 네트워크는 어디서나 광범위한 애플리케이션을 제공할 수 있습니다. 네트워크 성능을 향상시키기 위해서는 가능한 한 많은 WT에서 다양한 종류의 데이터를 수집해야 합니다. 각 AP는 10개 이상을 수용할 수 있어야 합니다.3 WT. 이러한 요구사항은 전형적인 중앙집중형 미디어 접근 제어 방식인 DSA를 사용함으로써 달성할 수 있는데, 이는 자원 활용 효율성이 높기 때문이다. 본 논문에서는 처리량 성능을 향상시키기 위해 세 가지 새로운 기술을 사용하는 새로운 DSA 방식을 제안합니다. (1) 대부분의 단말이 주기적으로 데이터를 전송하는 경향이 있다는 점을 고려하여 폴링 기반 방식, 즉 요청 폴링 및 데이터 폴링과 랜덤 액세스 방식을 모두 사용합니다. (2) 폴링을 통한 대역폭 활용 효율성을 높이기 위해 데이터 생성 시점에 따라 폴링 시점을 결정합니다. (3) AP는 최신 데이터 크기 분포에 따라 폴링되는 데이터 크기를 결정하고 데이터에 대해 WT를 직접 폴링합니다. 데이터 폴링 크기를 확실하게 결정할 수 없는 경우 AP는 데이터 폴링 대신 요청 폴링을 사용합니다. 시뮬레이션을 통해 제안된 방식이 기존 방식보다 더 나은 전송 성능을 제공하는지 확인합니다.

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.
