With the advent of 5G+ services, it has become increasingly convenient for mobile users to enjoy high quality multimedia content from CDN driven streaming and catch-up TV services (Netflix, iPlayer) in the (post-)COVID over-the-top (OTT) content rush. To relieve ISP owned fixed-line networks from CDN streamed multimedia traffic, system ideas (e.g., Wi-Stitch in [45]) have been proposed to (a) leverage 5G services and enable consumers to share cached multimedia content at the edge, and (b) consequently, and more importantly, reduce IP traffic at the core network. Unfortunately, given that contemporary multimedia content might be a monetised asset, these ideas do not take this important fact into account for shared content. We present EdgeMart - a content provider federated, and computationally sustainable networked (graphical) market economy for paid-sharing of cached licensed (OTT) content with autonomous users of a wireless edge network (WEN). EdgeMart is a unique oligopoly multimedia market (economy) that comprises competing networked sub-markets of non-cooperative content sellers/buyers - each sub-market consisting of a single buyer connected (networked) to only a subset of sellers. We prove that for any WEN-supported supply-demand topology, a pure strategy EdgeMart equilibrium exists that is (a) nearly efficient (in a microeconomic sense) indicating economy sustainability, (b) robust to edge user entry/exit, and (c) can be reached in poly-time (indicating computational sustainability). In addition, we experimentally show that for physical WENs of varying densities, a rationally selfish EdgeMart economy induces similar orders of multimedia IP traffic savings when compared to the ideal (relatively less practical), altruistic, and non-monetized “economy” implemented atop the recently introduced Wi-Stitch WEN-based content trading architecture. Moreover, the EdgeMart concept helps envision a regulated edge economy of opportunistic (pay per licensed file) client services for commercial OTT platforms.

随着 5G+ 服务的出现，移动用户在（后）新冠疫情 OTT 中享受来自 CDN 驱动的流媒体和追看电视服务（Netflix、iPlayer）的高质量多媒体内容变得越来越方便。 ）内容匆忙。为了减轻 ISP 拥有的固网网络受到 CDN 流媒体多媒体流量的影响，已经提出了系统想法（例如 [45] 中的Wi-Stitch ）：(a) 利用 5G 服务并使消费者能够在边缘共享缓存的多媒体内容，以及(b) 因此，更重要的是，减少了核心网络的 IP 流量。不幸的是，鉴于当代多媒体内容可能是一种货币化资产，这些想法在共享内容时并未考虑到这一重要事实。 我们推出EdgeMart- 内容提供商联合且计算可持续的网络（图形）市场经济，用于与无线边缘网络（WEN）的自主用户付费共享缓存许可（OTT）内容。EdgeMart 是一个独特的寡头垄断多媒体市场（经济），由非合作内容卖家/买家组成的竞争性网络子市场组成 - 每个子市场由一个仅与一部分卖家连接（联网）的买家组成。我们证明对于任何 WEN 支持的供需拓扑，存在一个纯策略 EdgeMart 均衡，它 (a) 几乎有效（在微观经济意义上）表明经济可持续性，(b) 对边缘用户进入/退出具有鲁棒性，并且 (c) 可以在多时间内达到（表明计算可持续性）。此外，我们通过实验表明，对于不同密度的物理 WEN，与理想的（相对不太实用的）、无私的和非货币化的“经济”相比，理性自私的 EdgeMart 经济会节省类似数量级的多媒体 IP 流量。最近推出了基于Wi-Stitch WEN的内容交易架构。此外，EdgeMart 概念有助于设想机会主义的受监管边缘经济（按许可文件付费）商业 OTT 平台的客户服务。
