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...
A major constraint for long term sustainability of wireless sensor networks (WSN) and the Internet of Things (IoT) is the limitation of their energy resources. Most wireless sensors are low energy consuming devices which are, in general, designed ...
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...
Localization is a key component of any mobile robot application. For any task a mobile robot might need to perform, precise knowledge of its pose within its environment is critical. Mobile robots employ a multitude of sensors to estimate position,...
