Optimizing Sensor Network Reprogramming via In-situ Reconfigurable Components

International audienceWireless reprogramming of sensor nodes is a critical requirement in long-lived Wireless Sensor Networks (WSNs) for several concerns, such as fixing bugs, upgrading the operating system and applications, and adapting applications behavior according to the physical environment. In such resource-poor platforms, the ability to efficiently delimit and reconfigure the necessary portion of sensor software--instead of updating the full binary image--is of vital importance. However, most of existing approaches in this field have not been widely adopted to date due to the extensive use of WSN resources or lack of generality. In this article, we therefore consider WSN programming models and run-time reconfiguration models as two interrelated factors and we present an integrated approach for addressing efficient reprogramming in WSNs. The middleware solution we propose, RemoWare, is characterized by mitigating the cost of post-deployment software updates on sensor nodes via the notion of in-situ reconfigurability and providing a component-based programming abstraction to facilitate the development of dynamic WSN applications. Our evaluation results show that RemoWare imposes a very low energy overhead in code distribution and component reconfiguration, and consumes approximately 6% of the total code memory on a TelosB sensor platform

The capability-based view of r&d and manufacturing interface in dynamic environments

Actual technological development does not occur solely when new technological products become available. It just effectively occurs by the application of value-adding processes. These processes can only occur after manufacturing processes become viable. Therefore, companies must remain agile during product development, manufacturing, and supply and value-adding processes. The needs of the extended company must be considered. This paper presents a theoretical discussion of the utilization of CBV literature as the basis for the configuration of the extended company. The qualitative, multidisciplinary, and theoretical research conducted for this paper was based on the inductive method. Manufacturing Management, Research and Development, Business Model, and Capability-Based View knowledge domains were evaluated to discover their potential contributions to design approach elements. The Capability-Based View is proposed as an approach that can be employed in the planning process for new enterprises. It can also be included in performance measurement processes. This approach enables monitoring and decision making during the evolution of Business Models by the use of organizational capabilities as the change-tolerant, performance measurement monitoring unit. This work contributes to the current literature by presenting an analysis of several knowledge domains based on the design approach. It also provides a discussion of methods of unification and suggests further research that should be conducted to enable the design of an adequate Business Model for dynamic environments
