Received radio frequency (RF) signal strength provides a cost-effective mechanism for distance estimation that is popularly used for range-based localization in wireless sensor networks (WSN). The typical method of determining sensor location usin...
Wireless sensor networks can potentially achieve perpetual maintenance-free operation by harnessing ambient energy from the environment. However, most environmental energy sources, such as vibrations, heat, radio frequency (RF) are usually inadequ...
This work proposes a game theoretic framework for managing the radio resources of wireless sensor nodes in Wireless Sensor Networks (WSNs). We consider data collecting sensor networks that are typical of environmental monitoring applications, whic...
As the size and node density of wireless sensor networks (WSN) increase, the energy conservation problem becomes more critical and the conventional methods become inadequate. This dissertation addresses two different problems in large scale WSNs w...
