Energy-Balanced Uneven Clustering Protocol Based on Regional Division for Sensor Networks

Abstract

In view of the unbalanced energy consumption of traditional cluster-based sensor networks, this paper proposes a type of uneven clustering protocol in data collection. The network is divided into inner and outer regions according to the distance between nodes and the base station. The inner region is consisted of several layers and nodes in outer region are deployed in grids of different sizes. Sensor data is collected by nodes in outer region and then is be transmitted to the inner region. Nodes in the inner region do data fusion and forward data from the lower layer to the higher one. Simulation results show that, compared with MTP and CDFUD, the proposed algorithm performs well in balance of energy consumption and could effectively prolong the network lifetime.

Measurement of the electric energy storage capacity in solar thermoelectric generators’ energy harvesting modules

“…Self-powered environmental sensors must obtain all the energy required for their operation from the environment, which requires minimizing energy consumption by optimizing the network operation, developing low-voltage systems, 9 and reducing the power required by the energy consumption of the sensor nodes. [10][11][12] Because most harvesters do not harvest energy continuously, but only during certain periods of time, such as when solar radiation is available in the case of STEGs, autonomous networks must rely on the energy surplus stored in a supercapacitor during the harvesting period. 13 Thus, to optimize the network parameters and to specify the power consumption of the sensor systems when powered by such energy harvesting systems, an accurate evaluation of the energy conversion module is required.…”
