모바일 방송 환경에서 정보 서버는 매 방송 주기마다 대규모 모바일 클라이언트 집단에 일련의 데이터 항목을 주기적으로 방송하고 모바일 클라이언트는 방송 채널에 도착할 때 필요한 데이터 항목을 검색합니다. 이러한 환경에서 데이터 전달 비용은 클라이언트 수와 무관합니다. 경매 및 주식 시세와 같은 많은 애플리케이션은 정확한 결과를 위해 클라이언트가 일관되고 최신 데이터를 읽어야 하는 읽기 전용 트랜잭션을 수행합니다. 이러한 환경을 위해 설계된 이전 동시성 제어 메커니즘은 클라이언트가 일관된 데이터를 읽을 수 있도록 보장하지만 보장할 수는 없습니다. 최신 통화 이를 통해 클라이언트는 최신 또는 최신 데이터를 읽을 수 있습니다. 본 논문에서는 최신 바인딩된 통화를 보장하는 효율적인 동시성 제어 메커니즘을 제안합니다. 업데이트 일관성, 모바일 방송 환경에 적합합니다. 최신 통화를 보장하기 위해 서버는 "가상" 방송 주기를 사용하여 제어 정보를 계산합니다. 이 제어 정보는 업데이트 일관성을 확인하는 데에도 사용됩니다. 따라서 제안된 메커니즘은 현재 방송주기에 커밋된 모든 데이터가 방송되도록 허용한다. 제안된 메커니즘의 성능을 평가하기 위해 트랜잭션 중단을 측정하는 시뮬레이션 실험을 수행했습니다. 결과는 제안된 메커니즘이 오래된 읽기를 생성하지 않음을 확인하고 제안된 메커니즘이 이전 메커니즘보다 더 적은 트랜잭션 중단을 생성한다는 것을 보여줍니다. 이는 데이터 불일치를 증가시키지 않고 더 높은 데이터 통화를 얻을 수 있음을 의미합니다.

Abstract: In mobile broadcasting environments, an information server periodically broadcasts a set of data items to a large mobile client population at every broadcast cycle and mobile clients retrieve the data items they need upon arrival at the broadcast channel. In such environments, the cost of data delivery is independent of the number of clients. Many applications such as auctions and stock quotes perform read-only transactions that require the clients to read consistent and current data for accurate result. Previous concurrency control mechanisms designed for such environments ensure that the clients read consistent data, but they cannot ensure latest-bound currency which allows the clients to read the latest or most up-to-date data. In this paper, we propose an efficient concurrency control mechanism that ensures latest-bound currency as well as update consistency, which is appropriate for the mobile broadcasting environments. To ensure latest-bound currency, the server computes control information using "virtual" broadcast cycles. This control information is also used for checking update consistency. Thus, the proposed mechanism allows all data committed in current broadcast cycle to be broadcast. We have performed simulation experiments to measure transaction aborts in order to evaluate the performance of the proposed mechanism. The result confirms that the proposed mechanism produces no stale reads and also shows that the proposed mechanism generates less transaction aborts than previous mechanisms, which implies that we can get higher data currency without increasing data inconsistency.

AB - In mobile broadcasting environments, an information server periodically broadcasts a set of data items to a large mobile client population at every broadcast cycle and mobile clients retrieve the data items they need upon arrival at the broadcast channel. In such environments, the cost of data delivery is independent of the number of clients. Many applications such as auctions and stock quotes perform read-only transactions that require the clients to read consistent and current data for accurate result. Previous concurrency control mechanisms designed for such environments ensure that the clients read consistent data, but they cannot ensure latest-bound currency which allows the clients to read the latest or most up-to-date data. In this paper, we propose an efficient concurrency control mechanism that ensures latest-bound currency as well as update consistency, which is appropriate for the mobile broadcasting environments. To ensure latest-bound currency, the server computes control information using "virtual" broadcast cycles. This control information is also used for checking update consistency.
