Poster: Multi-source Energy Harvesting for IoT nodes
Power consumption is a primary concern for wireless sensor networks. In order to reduce the use of batteries in the nodes, energy harvesting technologies have been considered. However, most of the existing solutions rely on a single energy source, thus potentially reducing the sensor sustainability. In this paper, we present a circuit that switches between multiple heterogeneous energy sources,...
متن کاملMulti-Source Energy Harvesting for Wireless Sensor Nodes
The past few years have seen an increasing interest in the development of wireless sensor networks. But the unsatisfactory or limited available energy source is one of the major bottlenecks which are limiting the wireless sensor technology from mass deployment. Ambient energy harvesting is the most promising solution towards autonomous sensor nodes by providing low cost, permanent, and maintena...
متن کاملOptimizing Energy Allocation for Energy Harvesting Node with Hybrid ARQ
—Efficiently using scarce energy is more critical for the nodes which are supplied by energy harvesting. However, it is difficult to optimize the transmit energy of each retransmission when future Channel State Information (CSI) and accurate retransmission number cannot be obtained in Hybrid Automatic Repeat Request (HARQ) system. In this paper, we propose a novel HARQ scheme to allocate the b...
متن کاملLazy Scheduling for Energy Harvesting Sensor Nodes
The paper studies the case of a sensor node which is operating with the power generated by an environmental source. We present our model of an energy driven scheduling scenario that is characterized by the capacity of the node's energy storage, the deadlines and the power dissipation of the tasks to be performed. Since the execution of these tasks requires a certain amount of energy as well as ...
متن کاملMaximizing Throughput in Energy-Harvesting Sensor Nodes
We consider an online throughput maximization problem in sensor nodes that can harvest energy. The sensor nodes generate and forward packets, which cost energy; they can also harvest energy from the environment, but the amount of energy that can be harvested is not known in advance. We give a number of algorithms and lower bounds for the case of a single node. We consider both the general case ...
