Wireless sensor networks (WSNs) are critical components of sustainable operations in every major industry. First stage of the WSN in the figure can potentially be fully supported by renewable energy sources. Use of non-traditional ambient energy sources such as low frequency vibrations and temperature differences in the environment in a set of emerging embedded and smart applications, some of which designated in recent Horizon 2020 documents.Our group, which consists of members of MEMS Center at METU Ankara and REDAR (Renewable Energy Design and Applications Research) group at METU NCC, has been working on energy harvesting MEMS components and interface circuits required to support self-powered embedded sensors. In the next phase of this collaborated research, more comprehensive solutions need to be delivered using hybrid interfaces to simultaneously take advantage of multiple energy harvesting modes with outmost efficiency. An effective hybrid harvester that will power-up many embedded applications can take advantage of vibration and thermal resources in parallel using piezoelectric and thermoelectric conversion respectively. This research focuses on:•Efficient (60-100%) piezoelectric (PZT) interface circuit development with 2.5 µW minimum input power,•Efficient (20-50%) thermoelectric (TE) interface circuit development with 0.25 V minimum input voltage,•Compact, hybrid interface circuit development using above components for harvesting 100s of µWatts simultaneously.

UAV-Driven Sustainable and Quality-Aware Data Collection in Robotic Wireless Sensor Networks
Gül, Ömer Melih; Erkmen, Aydan Müşerref; Kantarci, Burak (2022-01-01)
Energy-aware data collection is of paramount importance for robotic and wireless sensor networks. Although static sink-aided cluster-based protocols provide energy-efficient solutions, UAV-aided approaches can be considered as better alternatives to reduce energy consumption while data acquisition compared with static sinks. Most of the existing UAV-driven solutions have not considered a limit on battery capacity of the UAV, which needs to be considered in a practical manner. This paper investigates energy-...
MOFCA: Multi-objective fuzzy clustering algorithm for wireless sensor networks
SERT, SEYYİT ALPER; Bagci, Hakan; Yazıcı, Adnan (2015-05-01)
This study introduces a new clustering approach which is not only energy-efficient but also distribution-independent for wireless sensor networks (WSNs). Clustering is used as a means of efficient data gathering technique in terms of energy consumption. In clustered networks, each node transmits acquired data to a cluster-head which the nodes belong to. After a cluster-head collects all the data from all member nodes, it transmits the data to the base station (sink) either in a compressed or uncompressed ma...
Finite-horizon online energy-efficient transmission scheduling schemes for communication links
Bacınoğlu, Baran Tan; Uysal Bıyıkoğlu, Elif; Department of Electrical and Electronics Engineering (2013)
The proliferation of embedded systems, mobile devices, wireless sensor applications and increasing global demand for energy directed research attention toward self-sustainable and environmentally friendly systems. In the field of communications, this new trend pointed out the need for study of energy constrained communication and networking. Particularly, in the literature, energy efficient transmission schemes have been well studied for various cases. However, fundamental results have been obtained mostly ...
Lifetime analysis for wireless sensor networks
Öğünlü, Bilal; Bazlamaçcı, Cüneyt Fehmi; Department of Electrical and Electronics Engineering (2004)
Sensor technologies are vital today in gathering information about certain environments and wireless sensor networks are getting more widespread use everyday. These networks are characterized by a number of sensor nodes deployed in the field for the observation of some phenomena. Due to the limited battery capacity in sensor nodes, energy efficiency is a major and challenging problem in such power-constrained networks. Some of the network design parameters have a direct impact on the network̕s lifetime. The...
Path planning and localization for mobile anchor based wireless sensor networks
Erdemir, Ecenaz; Tuncer, Temel Engin; Department of Electrical and Electronics Engineering (2017)
In wireless sensor networks, sensors with limited resources are distributed in a wide area. Localizing the sensors is an important problem. Anchor nodes with known positions are used for sensor localization. A simple and efficient way of generating anchor nodes is to use mobile anchors which have built-in GPS units. In this thesis, a single mobile anchor is used to traverse the region of interest to communicate with the sensor nodes and identify their positions. Therefore planning the best trajectory for th...
