System-level Support for Macroprogramming of Networked Sensing Applications

چکیده
Wireless sensor networks (WSNs) provide low-cost, embedded sense-and-respond capability, and are therefore an integral part of the vision of pervasive computing. Most research on WSNs to date has focused on the development of efficient protocols for infrastructure establishment. Application development for WSNs is still very daunting for the non-expert. This paper proposes hierarchical layers of abstractions to categorize the functionality of various WSN protocols from a programming perspective. We then address the issue of systemlevel support for programming models in sensor networks, and describe the design of the DART runtime system, which supports a macroprogramming model called the Abstract Task Graph. DART prototypes for two different target platforms have been implemented. The modular structure of the runtime is inspired by our proposed layers of programming abstraction. The design of DART simplifies software synthesis of ATaG programs, and enables near plug-and-play integration of different protocols and services at the lower layers with minimal impact on the higher layers.

A Compilation Framework for Macroprogramming Networked Sensors
Macroprogramming—the technique of specifying the behavior of the system, as opposed to the constituent nodes—provides application developers with high level abstractions that alleviate the programming burden in developing wireless sensor network (WSN) applications. However, as the semantic gap between macroprogramming abstractions and node-level code is considerably wider than in traditional pr...

Structural sensing and control is an important application of the DDDAS paradigm. Our work on structural sensing and control has several key aspects, including model reduction, control, simulation, and validation. Motivated by our work on validation using an actual three-storeyed structure, we are developing a comprehensive systems environment, Omni, for macroprogramming sensor networks. While ...
متن کاملEnabling Scoping in Sensor Network Macroprogramming
Wireless sensor networks are increasingly employed to develop sophisticated applications beyond simple data gathering. In these scenarios, heterogeneous nodes are deployed, and multiple parallel activities must be performed to achieve the application goals. Therefore, application developers require the ability to partition the system based on the node characteristics, and specify the interactio...
متن کاملHybrid Macroprogramming Wireless Networks of Embedded Systems with Declarative Naming
Wireless Networks of Embedded Systems (WNES) is notoriously difficult and tedious to program. The difficulty is mostly originated from low-level details in system and network programming. This includes distributedly managing and accessing resources from a dynamic set of nodes in hostile and volatile networks. To simplify WNES programming, we propose Declarative Resource Naming (DRN) that abstra...
متن کاملDesigninga Neuro-Sliding Mode Controller for Networked Control Systems with Packet Dropout
This paper addresses control design in networked control system by considering stochastic packet dropouts in the forward path of the control loop. The packet dropouts are modelled by mutually independent stochastic variables satisfying Bernoulli binary distribution. A sliding mode controller is utilized to overcome the adverse influences of stochastic packet dropouts in networked control system...
