The Internet of Things (IoT) embeds sensors, actuators and computation into everyday 'things' such as lights and thermostats. These things form low-power wireless networks connecting to the Internet via IPv6 for monitoring and control. Such IoT systems are increasingly subject to runtime reconfiguration, wherein new hardware and software may be installed dynamically to accommodate changing application...
Smart applications enable pervasive and informed interactions between the physical and digital worlds. These applications are deployed on resource constrained wireless sensor networks and are commonly implemented using software modularization schemes such as components and services. Composing smart applications at the abstraction level offered by embedded software modularization schemes is complex...
Creating and managing applications for Wireless Sensor Networks (WSNs) is complicated by large scale, resource constraints and network dynamics. Reconfigurable component models minimize these complexities throughout the application lifecycle. However, contemporary component based middleware for WSNs is limited by its poor support for distribution. This paper introduces the Loosely-coupled Component...
Contemporary wireless sensor network deployments are long-lived, large scale and resource constrained. Longevity demands mechanisms that support reconfiguration to meet changing application requirements, large scale demands high-level abstractions to support network management and stringent resource constraints necessitate a high degree of efficiency in middleware to support application development...
Since wireless sensor network applications are ever growing in scale and complexity, managers require strong formal guarantees that any changes done to the system can be enacted safely. This paper presents the formalisation and analysis of the semantics of policies, tiny software artefacts used to orchestrate wireless sensor network applications. The semantics of policies is formalised in terms of...
