Methodology of cooperative spectrum sensing and dynamic access to the channels in WSN

Autor: Johan L. T. Garzon, Carlos Eduardo Pereira, Jean Michel Winter, Alvaro Augusto Almeida de Salles, Ivan Muller

Publikováno v: Physical Communication. 31:28-39

Cognition into wireless sensors is a current paradigm to improve the performance of wireless sensor networks (WSN) and the efficient use of the radio frequency spectrum. The classic static allocation of the radio frequency bands causes coexistence pr

Towards a Wireless HART Network with Spectrum Sensing

Autor: Carlos Eduardo Pereira, Ivan Muller, Jean Michel Winter, C. João

Publikováno v: IFAC Proceedings Volumes. 47:9744-9749

The use of wireless communication systems for critical applications in a shared medium presents a lot of challenges regarding its reliability and robustness. The WirelessHART protocol, although robust has a lack of active mechanisms for coexistence,
