增强信息（AgI）服务允许用户消费由处理源信息以创建实时增强价值的服务功能链的执行产生的信息。应用包括遥感数据的实时分析、实时计算机视觉、个性化视频流和增强现实等。我们考虑的问题，AgI服务的最佳分布在无线计算网络中，其中节点都配备了通信和计算资源。我们的无线计算网络容量区域的特点和设计一个联合流调度和资源分配算法，稳定底层排队系统，同时实现网络成本任意接近最小值，在网络延迟的权衡。我们的解决方案捕捉独特的链接和流缩放方面的AgI服务，同时利用无线信道上的广播方法编码方案的使用。
Augmented information (AgI) services allow users to consume information that results from the execution of a chain of service functions that process source information to create real-time augmented value. Applications include real-time analysis of remote sensing data, real-time computer vision, personalized video streaming, and augmented reality, among others. We consider the problem of optimal distribution of AgI services over a wireless computing network, in which nodes are equipped with both communication and computing resources. We characterize the wireless computing network capacity region and design a joint flow scheduling and resource allocation algorithm that stabilizes the underlying queuing system while achieving a network cost arbitrarily close to the minimum, with a tradeoff in network delay. Our solution captures the unique chaining and flow scaling aspects of AgI services while exploiting the use of the broadcast approach coding scheme over the wireless channel.
