Smart spaces provide a platform for cooperative service construction by many devices in the Internet of Things (IoT) environments. When a service is constructed the service needs delivering to appropriate clients, which is typically implemented using the subscription operation (i.e., information-driven service construction). The passive form of subscription is ineffective in the IoT settings since the centralized solution—smart space information broker—needs to control all service construction updates and to notify all interested clients. This article considers the problem of active control for information-driven service construction when each client can use its own (individual) strategy to (additionally) control ongoing updates in the subscribed information. Five strategies for active control are selected for this study. For some simplified assumptions, analytical estimates are provided. For close-to-real evaluation of the strategies a simulation model is developed, based on which several performance metrics are experimentally studied.

2. Background And Motivation

In IoT environments, a service-oriented application can be created as a smart space. The latter forms a sparse-connected multi-agent system deployed on various digital devices, including mobile and embedded IoT-enabled equipment (Augusto, Callaghan, Cook, Kameas, & Satoh, 2013; Korzun, Balandin, Kashevnik, Smirnov, & Gurtov, 2017). Software agents run on the devices and interact over the shared information content to create services together.
