Applying Aspect-Oriented Design Methodology to Manage Time-Validity of Information in Internet-of-Things Systems

The Internet of Things (IoT) is becoming increasingly ubiquitous, typified in software by large-scale multi-agent systems of heterogeneous agents. IoT devices are constrained in terms of memory and processing power, limiting their capacity to hold large sets of information upon which decision-making logic must execute. IoT devices are also frequently deployed as distributed sensors constrained in terms of time, location and communications bandwidth. These constraints demand a level of multi-agent communication and co-ordination to provide accurate, up-to-date information on-demand to different intelligent agents in the system. In this paper, we propose a novel method by which Aspect-Oriented Software Design can be applied to managing the validity of time-constrained data in IoT systems while decoupling the application code from this concern.
