SYNCHRONIZING DATA TRANSMISSION OVER WIRELESS NETWORKS |
摘要 |
Techniques for providing an uninterrupted data stream to a mobile node are disclosed. In a first technique, a time stamp is inserted at some point in the wireless network and the time stamp is used along with a tolerance value to determine when to transmit a packet in a data stream. By transmitting the packets at the same adjusted time, transmission to mobile nodes is synchronized. A second technique uses duplication of data stream content to avoid an interruption in the data stream at a mobile node. A third technique uses an error correcting code to avoid interruption of the data stream at a mobile node. A fourth technique uses a sequence number inserted into packets in the data stream at the content server to synchronize transmission to mobile nodes.
