普适系统中的管理不能依赖人工干预或集中决策功能。它必须下放，基于本地决策和反馈控制回路嵌入自主组件。我们以前已经提出了自我管理单元（SMC）作为一种架构模式，用于构建无处不在的应用程序，其中SMC由硬件和软件组件组成，形成一个自治的管理域。SMC可以以不同的规模实现，从用于健康监测的体域网络到整个房间或更大的分布式设置。然而，为了扩展到更大的系统，SMC必须彼此协作，并在更大的SMC结构中联合或组合。本文讨论了SMC之间的交互需求，并提出了实现对等和组合交互的关键抽象和协议。这些使SMC能够交换数据，对外部事件做出反应，并交换管理其协作的策略。可动态定制的接口用于封装和交互中介。虽然这里使用的示例是基于医疗保健场景，但本文中描述的原则和抽象更普遍适用。
Management in pervasive systems cannot rely on human intervention or centralised decision-making functions. It must be devolved, based on local decision-making and feedback control-loops embedded in autonomous components. We have previously proposed the self-managed cell (SMC) as an architectural pattern for building ubiquitous applications, where a SMC consists of hardware and software components that form an autonomous administrative domain. SMCs may be realised at different scales, from body-area networks for health monitoring, to an entire room or larger distributed settings. However, to scale to larger systems, SMCs must collaborate with each other, and federate or compose in larger SMC structures. This paper discusses requirements for interactions between SMCs and proposes key abstractions and protocols for realising peer-to-peer and composition interactions. These enable SMCs to exchange data, react to external events and exchange policies that govern their collaboration. Dynamically customisable interfaces are used for encapsulation and interaction mediation. Although the examples used here are based on healthcare scenarios, the principles and abstractions described in the paper are more generally applicable.
