Abstract: Methods and devices for processing and retransmitting highway communication system transmissions include determining a reliability of a received message and including an indication of the reliability in retransmitted transmissions. Reliability of received messages may be based on a signal strength of the received peer transmission, comparison of the signal strength to a distance to the transmitter based on message contents, the age of the received message, the signal quality of the received message, and other parameters. An indication of the determined reliability may be included in retransmissions of the message to enable other vehicles and receiver units in the highway communication system to benefit from the reliability determination. Message reliability may be used as part of prioritizing messages for processing. Messages may be processed according to priority so that high priority messages are processed before lower priority messages.

Abstract: Error correction coding for streaming communication is provided. A streaming problem is modeled as a non-multicast network problem with a nested receiver structure. Each packet in the streaming problem corresponds to a link, and each deadline in the streaming problem corresponds to a receiver in the non-multicast network problem. For the non-multicast network problem, content to be transmitted in multiple packets to multiple receivers is obtained. Each of the receivers is required to decode specific independent messages from the content, at given time steps, and has access to a subset of the content received by another receiver. The content is allocated into multiple packets to be transmitted on multiple links. No coding occurs across information demanded by different receivers. A capacity region defines a set of information rate vectors that can be communicated to the receivers successfully. A rate vector is successfully communicated if it complies with various inequalities.

Abstract: In one embodiment, protocol violations of a particular protocol are induced at one or more predetermined intervals within a particular stream of information encoded according to the particular protocol in order to produce a marked particular stream of information for use in subsequent identification of the marked particular stream of information. The marked stream is multiplexed or otherwise communicated to a second device. The second device detects, and typically corrects, the induced protocol violations. And based on which stream of information included the induced protocol violations and the multiplexing/distribution pattern of the other streams of information, the second device can identify which stream is which and process or forward accordingly.

Abstract: A serial buffer monitors an incoming stream of packets to identify single missing packets and multiple consecutive missing packets. Upon detecting multiple consecutive missing packets, an interrupt is generated, thereby stopping the data transfer. Upon detecting a single missing packet, a single missing packet identifier is inserted into the packet header of the packet that resulted in identification of the single missing packet. The incoming packets, including any inserted single missing packet identifiers, are written to a queue. When the water level reaches the water mark of the queue, the stored packets are read to create an outgoing packet stream. When a packet read from the queue includes an inserted single missing packet identifier, a dummy packet (e.g., a packet having a data payload of all zeros) is inserted into the outgoing packet stream. As a result, real-time applications are capable of processing the outgoing packet stream in a constant fashion.

Abstract translation: 串行缓冲器监视传入的数据包流，以识别单个丢失的数据包和多个连续的丢失数据包。 在检测到多个连续丢失数据包时，产生中断，从而停止数据传输。 在检测到单个丢失的分组时，将单个丢失的分组标识符插入到分组的分组报头中，导致单个丢失分组的标识。 传入的数据包，包括任何插入的单个丢失的数据包标识符，被写入队列。 当水位达到队列的水位时，读取存储的数据包以创建输出数据包流。 当从队列读取的分组包括插入的单个丢失的分组标识符时，将虚拟分组（例如，具有全零的数据有效载荷的分组）插入到输出分组流中。 因此，实时应用能够以恒定的方式处理输出分组流。
