Description A new programming language for the deployment of wireless sensor networksWireless sensor networks (WSNs) are expected to play a critical role in the next computing revolution of cooperating objects and smart embedded devices, yet industry adoption is below expectations. makeSense will lower the barrier for using WSNs by simplifying programming and creating a direct, technical link to business processes. This will allow e.g. more intelligent facility or supply chain management, resulting in better insight, energy efficiency and comfort.Currently, total cost of deployment of a sensor network is not dominated by hardware (a few 100 to a few 1,000 €) but by the cost of program¬ming an application that carries out the task of sensing (10,000s of €). This task requires highly skilled and paid embedded software engineers who know details of the used sensors and system platform. This also affects total cost of ownership as re-configuration requires the same skills. The tool chain developed by makeSense will reduce this need by providing a macro language that allows a skilled deve¬loper without explicit WSN knowledge to build such an application using a set of pre-defined abstractions. On top of this, makeSense will provide a modelling layer that allows business process modellers to effectively model processes that interact with the real world, as sensed by the WSN, with unprecedented integration. By re-using concrete abstractions across scenarios, we expect the WSN development cost to be reduced by 50 %. Our approach requires some additional cost for process modelling, however overall, this could still reduce the cost compared to other systems currently used (such as SCADA) by around 30%. By substantially reducing the cost of deployment and ownership of sensor networks, makeSense will help to make many applications economically feasible, that are beneficial for society and individuals that would not be available if their development was cumbersome and hence time-consuming and expensive, e.g. to implement energy saving in facility management or optimization of supply chains, leading to a greener, more competitive European economy.While SAP expects to integrate the findings of makeSense in commercial tools for business process automation, ACCIONA will include makeSense technologies in their technology portfolio and expects to increase the amount of building projects by about 15% in 5 years.
