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.

f4-sensors-12-10659: Proposed network topology.

Mentions: First, in order to develop our solution, we will assume that the aforementioned Smart City architecture is representative. Taking its main elements as a reference, we can state that the services will be deployed over a network with a topology like the one depicted in Figure 4, which is comprised of the following components: (i) sensor nodes; (ii) base stations; (iii) gateways and (iv) HPC servers, organized as follows.
