Abstract-Smartphones, PDA, Sensors, Actuators, Phidgets and Smart Objects (i.e. objects with processing and networking capabilities) are more and more present in everyday's life. Merging all these technologies with the Internet is often described as 'Internet of Things' (IoT). In the IoT vision, Things around us provide a pervasive network of interacting and interconnected devices. However building IoT applications is a long and arduous work, reserved for specialists, requiring specific knowledges in terms of network protocols and programming languages. The lack of widespread and easy-to-configure solutions is an obstacle for the development of this area. A universal framework, offering simplification and standardization, could facilitate the emergence of this promising field in terms of applications and business. IoT needs a solid foundation for rapid, simple development and deployment of new services. In this paper, we present DLITe, a universal framework for building IoT applications over heterogeneous sets of small devices. D-LITe offers solutions for deploying application's logic, and executing it on Smart Objects despite their heterogeneity. An implementation of DLITe on tiny devices, such as TelosB motes, allows to show that our framework is realistic even with the constraints of such devices.

“…From the WSN literature, we identify tinyDB [4] with its extensions as an established query service and pub/sub [11,12,13,14,15,16] as an event service. As mentioned before, TinyDB treats sensor data as a single table (sensors) with one column per sensor type.…”

A prominent functionality of a Wireless Sensor Network (WSN) is environmental monitoring. For this purpose the WSN creates a model for the real world by using abstractions to parse the collected data. Being cross-layer and application-oriented, most of WSN research does not allow for a widely accepted abstraction. A few approaches such as database-oriented and publish/subscribe provide acceptable abstractions by reducing application dependency and hiding communication details. Unfortunately, these approaches ignore the spatial correlation of sensor readings and still address single sensor nodes. In this work we present a novel approach based on a "world model" that exploits the spatial correlation of sensor readings and represents them as a collection of regions called maps. Maps are a natural way for the presentation of the physical world and its physical phenomena over space and time. Our Map-based World Model (MWM) abstracts from low-level communication issues and supports general applications by allowing for efficient event detection, prediction and queries. In addition our MWM unifies the monitoring of physical phenomena with network monitoring which maximizes its generality. Using two case studies we highlight the simplicity and also the versatility of the proposed architecture. From our approach we deduce a general modeling and design methodology for WSNs.

“…The current state-of-the-art in typing of messages in constrained environments either provides no support for sub-typing [1][2][3][4] or sub-optimal support for sub-typing based upon textual identifiers [5,6] or simple numerical encoding techniques [7][8][9]. The verbosity of current approaches holds little advantage in constrained machine-to-machine environments.…”

Abstract. Sub-typing of data improves reuse and allows for reasoning at different levels of abstraction; however, it is seldom applied in resource constrained environments. The key reason behind this is the increase in overhead that is caused by including hierarchical information in data types as compared to a flat list. Where hierarchical data typing is used, it is often represented using verbose textual identifiers or numerical encodings that are suboptimal with regards to space. In this paper, we present an encoding function for hierarchically typed information, based on the properties of prime numbers. It provides a compact representation of types, fast subsumption testing even on resource constrained platforms and support for the evolution of the data type hierarchy. We demonstrate the feasibility of our approach on two representative communication models in constrained environments; a publish/subscribe event bus and a RESTful application protocol. We evaluate the performance of our encoding function and show that it has limited overhead compared to a flat list of data types and that this overhead is outweighed by reduced memory and communication overhead once applied.
