We propose an adaptive parameter balancing scheme in a variational framework where a convex composite energy functional that consists of data fidelity and regularization is optimized. In our adaptive parameter balancing, the relative weight is assigned to each term of the energy for indicating its significance to the total energy, and is automatically determined based on the data fidelity measu...

Traditional management of electricity portfolios is focused on the day-ahead market and futures of longer maturity. Market participants use these markets to trade any excess production or consumption in their portfolio and balance their total position. Within limits, market participants can also resort to the balancing energy market to close their positions. The energy transactions on the balan...

Routing in Wireless Sensor Networks (WSNs) is a very challenging task due to the large number of nodes, their mobility and lack of proper infrastructure. Since the sensors are battery powered devices, energy efficiency is considered as one of the main factors in designing routing protocols in WSNs. Most of energy-aware routing protocols are mere energy savers that attempt to decrease the energy...

Data collection is performed by using the combination of compressive sensing and score based load balancing algorithm. To make the energy efficient network, the score based load balancing algorithm finds the path for routing the data towards the destination. The sensor nodes are divided into clusters and each cluster has one cluster head depending on their energy. The compressive sensing compre...

Many physical systems, such as water/electricity distribution networks, are monitored by battery-powered Wireless Sensor Networks (WSNs). Since battery replacement of sensor nodes is generally difficult, long-term monitoring can be only achieved if the operation of the WSN nodes contributes to a long WSN lifetime. Two prominent techniques to long WSN lifetime are i) optimal sensor activation an...

One of the main goals of recent developments in the Smart Grid area is to increase the use of renewable energy sources. These sources are characterized by energy fluctuations that might lead to energy imbalances and congestions in the electricity grid. Exploiting inherent flexibilities, which exist in both energy production and consumption, is the key to solving these problems. Flexibilities ca...
