The system consists of an array of affordable transducers that can operate as transceivers in the 20 40 kHz region and withstand the high pressures (up to 500 bar).
This paper presents a wide measurement range fiber optic inclinometer for a stable sensing principle and simple sensor structure, which were realized using a single transmissive grating panel, reflective mirror, and optical fibers as transceivers.
A WSN is composed of a number of tiny and low-power devices such as transceivers, actuators, and oscillators [5].
In this perspective, the distinction between transmitter and receiver of information is blurred; agents are seen as "transceivers" (ibid), interactively participating to the knowledge creation process.
The small sensor size and the long operation time significantly constrain the consumable energy, particularly because the majority of the available space inside the agents is already occupied by hardware such as transceivers and environmental sensors.
Unfortunately, today's commodity network devices are not energy proportional, mainly because the components of the network devices (such as transceivers, line cards, fans, etc) are always kept on regardless of whether they have data packets to transfer or not, leading to a significant energy wastage.
Dynamic private channel (DPC) protocol introduced in Hung et al. (2002) is based on the assumption that nodes are equipped with as many transceivers as the number of channels.
The multi-channel MAC protocol proposed in Nasipuri et al. (1999) it is also assumed that each node has as many transceivers as the number of available channels, but here nodes are capable to listen to all these channels simultaneously.
This paper addresses the emerging field of compressive sensing for stripmap synthetic aperture imaging using transceiver as well as single-transmitter and multi-receiver systems so as to overcome the spatial Nyquist criterion.
