摘要： The present invention relates to an improved method of de-jittering MPEG-2 and MPEG-4 data that is transmitted over a network. First, a network system jitter associated with periodic reference data packets is estimated. Then, the estimated system jitter is used to adjust clock-stamped reference values in the data packets before they are provided to the PLL for clock synchronization. The invented de-jittering method improves the PLL's ability to synchronize the MPEG data and provides for a better quality playback.

摘要： The present invention provides a method for selecting and routing data in an ad-hoc mobile wireless network having a plurality of Nodes including multiple sources and destinations. The method includes sending a forward control packet from a source to the destination via at least one intermediate Node at intervals of time, where the intermediate Node is randomly selected. Each of the intermediate Nodes store weights of the neighbor Nodes. When the forward control packets reach the destination Node, they are evaluated in accordance with one or more given parameters and send back as backward control packets storing the evaluation results. As each of the intermediate Nodes receive the backward control packets, the weights of the corresponding neighbor Nodes are modified based on the stored evaluation results. Similarly, as the backward control packets are received at the source Nodes and the weights of the corresponding neighbor Nodes are modified based on the stored evaluation results. Finally, a group of routing routes to the destination are selected based on the modified weights of the neighbor Nodes and data packets are send from the source to the destination via the intermediate Nodes upon selection of the group.

摘要翻译：本发明提供了一种在具有多个节点的自组织移动无线网络中选择和路由数据的方法，该多个节点包括多个源和目的地。所述方法包括：经由至少一个中间节点从源向目的地发送前向控制分组，其中中间节点随机选择。每个中间节点存储邻居节点的权重。当前向控制分组到达目的地节点时，它们根据一个或多个给定参数进行评估，并作为存储评估结果的后向控制分组发回。当每个中间节点接收到后向控制分组时，根据所存储的评估结果修改对应的相邻节点的权重。类似地，由于在源节点处接收到后向控制分组，并且基于所存储的评估结果来修改对应的相邻节点的权重。最后，基于邻居节点的修改权重选择到目的地的一组路由路由，并且在选择组时，经由中间节点从源向目的地发送数据分组。
