El pr\u00f3ximo Viernes 11 de Junio el profesor Mohammad S. Obaidat impartir\u00e1 una conferencia relacionada con las redes de sensores medioambientales y los problemas de limitaci\u00f3n del consumo de los sensores. La conferencia se impartir\u00e1 en el Aula de Grados de la Escuela T\u00e9cnica Superior de Ingenier\u00eda Inform\u00e1tica de Sevilla. A continuaci\u00f3n se resume el tema de la conferencia.<\/p>\n
Abstract<\/strong>: Wireless Sensor Networks (WSNs) are popular nowadays for applications ranging from environmental monitoring to object tracking and surveillance. But the sensors which are deployed are energy constrained. The nodes in WSNs deplete of their very limited energy over time. In this work, we consider a network of rechargeable sensors deployed in a random sensing environment. Using Markov Decision Processes (MDP), we analyze the sensor nodes having different levels of energies in the batteries, so as to maximize a generalized system performance in terms of recharge delay and the number of sensor nodes recharged. We have formulated a relationship between the residual energy level of a sensor node and the recharge delay. The simulation results establish the effectiveness of our approach in decreasing the number of passive nodes and the recharge delay in WSNs.<\/p>\n
