摘要:
由于无线网络的带宽窄、不可靠和频繁断接等限制,传统的基于应答消息的数据同步算法不再适用。提出一种基于时间戳的多次传输算法来解决这个问题。它缓存移动基站发给移动客户机的消息,对比版本信息时间戳识别移动客户机丢失的消息,并重新发送这些消息。通过建立数学模型与已有的经典移动数据同步算法作比较,证明其更能有效地降低数据访问出错率,保持数据的一致性,且移动客户机在接收到消息后无需发送应答消息,更适合在通信不稳定的无线网络环境下使用
Abstract:
Because of wireless network's features such as narrow network width,bad network reliability,and frequent disconnection,the traditional data synchronization algorithm which depends on the responding message isn't suitable any more.Represent a new multi-transport algorithm based on the latest timestamp to resolve this problem.It caches the messages that mobile support station sends to mobile hosts,verify which messages are lost by comparing the messages' timestamp,and then resend the lost messages to the mobile host.During setup mathematical models and comparing with these classic mobile data synchronization algorithms,it is proved that it can reduce the data access mishit ratio, keep the data consistency better,and the mobile host doesn't need to send a response to the mobile support station which is more suitable for the instable wireless network environment
