    • Disclosed is a general model and method for computing performance bounds in multi-hop wireless networks. Rather than focusing on computing asymptotic performance bounds under assumptions of homogeneity or randomness in the network topology and/or workload, the present invention accommodates any given network, technology, interference model, routing paradigm, and workload. Using a conflict graph to formally characterize the impact of wireless interference on the performance of multi-hop wireless networks, methods for computing upper and lower bounds on the capacity of a given wireless network are detailed. Besides computing network capacity, the model and method disclosed can also enable or benefit other applications including maximizing fairness and minimizing maximum link utilization.
    • 公开了一种用于计算多跳无线网络中的性能界限的通用模型和方法。 本发明不考虑在网络拓扑和/或工作负载中的均匀性或随机性假设下计算渐近性能界限,而是适应任何给定的网络,技术,干扰模型,路由范例和工作负载。 使用冲突图形式表征无线干扰对多跳无线网络性能的影响,详细描述了计算给定无线网络容量的上限和下限的方法。 除了计算网络容量之外,所公开的模型和方法还可以实现或受益于其他应用,包括最大化公平性并最小化最大链路利用率。

    • A system and method that can receive, buffer, and asynchronously combine data from various incoming data packets is disclosed. The system and method can do so by, first, receiving incoming packets of one or multiple generations that have incoming data and incoming metadata, with the incoming data of each of the incoming packets that are of a first generation being a combination of a first, original set of data vectors, and the incoming metadata of each of the first generation of incoming packets including an indicator for the first generation. Second, once these incoming packets are received, the system and method can buffer them based on the indicator and, asynchronously from the receiving and buffering, combine the incoming data in the buffered, first generation incoming packets into outgoing data in an outgoing packet.
    • 公开了可以接收,缓冲和异步地组合来自各种输入数据分组的数据的系统和方法。 系统和方法可以通过首先接收具有传入数据和传入元数据的一代或多代的传入分组,其中第一代的每个输入分组的输入数据是第一, 原始数据向量集合,以及第一代进入分组中的每一个的传入元数据,包括用于第一代的指示符。 第二,一旦这些传入的分组被接收,系统和方法可以基于指示符缓冲它们,并且从接收和缓冲异步地将缓冲的第一代进入分组中的输入数据组合成输出分组中的输出数据。
