Bottom Line: Ubiquitous sensor network deployments, such as the ones found in Smart cities and Ambient intelligence applications, require constantly increasing high computational demands in order to process data and offer services to users.This paper proposes an energy-minimization workload assignment technique, based on heterogeneity and application-awareness, that redistributes low-demand computational tasks from high-performance facilities to idle nodes with low and medium resources in the WSN infrastructure.These non-optimal allocation policies reduce the energy consumed by the whole infrastructure and the total execution time.

ABSTRACT
Ubiquitous sensor network deployments, such as the ones found in Smart cities and Ambient intelligence applications, require constantly increasing high computational demands in order to process data and offer services to users. The nature of these applications imply the usage of data centers. Research has paid much attention to the energy consumption of the sensor nodes in WSNs infrastructures. However, supercomputing facilities are the ones presenting a higher economic and environmental impact due to their very high power consumption. The latter problem, however, has been disregarded in the field of smart environment services. This paper proposes an energy-minimization workload assignment technique, based on heterogeneity and application-awareness, that redistributes low-demand computational tasks from high-performance facilities to idle nodes with low and medium resources in the WSN infrastructure. These non-optimal allocation policies reduce the energy consumed by the whole infrastructure and the total execution time.

Mentions: In spite of all these measures, the energy consumption of data centers keeps growing, mainly because of the dramatic increase of supercomputing facilities. Figure 2 shows the number of world servers installed from 2000 to 2010. As it can be seen, the increase is currently reaching 5.75 million new servers per year. This translates into huge amounts of power consumption, mainly devoted to the infrastructure of the data centers and the volume servers (see Figure 3. The total energy usage by data centers is expected to exceed 400 GWh/year on 2015. Bearing this data in mind, it is clear that current effort is not enough, and that further research should be made to reduce power consumption of supercomputing facilities.
