Environmental monitoring sensor networks often operate in remote locations and thus must be designed for energy-efficiency and reliability. The first goal of energy efficiency can be achieved through low-power design of the monitoring hardware, often supplemented by energy management schemes of varying complexity and sophistication. In case of sensor nodes(More)
Wireless sensor networks can be used to collect data in support of a number of tasks such as ecosystem or structural monitoring. When deployed in remote areas with little or no communication and power infrastructure, these networks face a number of power and reliability challenges. To collect adequate amount of data over long periods, operation of such(More)
Energy neutrality is the desired mode of operation of many sensor networks used for environmental monitoring. Intelligent energy harvesting networks, composed of nodes equipped with solar panels and other types of power-scavenging devices, can plan and manage their operations according to short and long-term predictions of ambient energy availability.

Minimization of energy consumption of environmental monitoring systems is important to ensure their extended operational lifetime and low maintenance costs. One possible way to conserve energy is the use of low-frequency analog-to-digital conversion devices and associated data sampling techniques. In this paper, a new approach to lowering sampling frequency(More)
