Energy-Efficient Resource Allocation in Wireless Networks: An Overview of Game-Theoretic Approaches

, 2007
An overview of game-theoretic approaches to energy-efficient resource allocation in wireless networks is presented. Focusing on multiple-access networks, it is demonstrated that game theory can be used as an effective tool to study resource allocation in

Joint Design of Transmit Waveforms for Object Tracking in Coexisting Multimodal Sensing Systems

Sensors, 2019
We examine a multiple object tracking problem by jointly optimizing the transmit waveforms used in a multimodal system. Coexisting sensors in this system were assumed to share the same spectrum.

Energy-efficient on-node signal processing for vibration monitoring [PDF]

2014 IEEE Ninth International Conference on Intelligent Sensors, Sensor Networks and Information Processing (ISSNIP), 2014
In recent years, the use of wireless sensor networks for vibration monitoring is emphasized, because of its capability to continuously monitor at hard-to-reach locations of complex machines. Low power consumption is one of the main requirements for the sensor nodes in continuous and long-term vibration monitoring.

An Energy Scalable Functional Unit for Sensor Signal Processing [PDF]

2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007
Low power signal processing functionality is required for wireless sensor network nodes due to their limited battery life. Previously, we have proposed a reconfigurable array of DSP acceleration functional units for such a sensor node. The array maximizes operating life by matching system power consumption to available energy through power scalable ...
