Towards a WirelessHART Network with Spectrum Sensing
نویسندگان
چکیده
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, becoming vulnerable for interference sources. This paper proposes an expansion of the WirelessHART coexistence mechanisms, allowing an online analysis of the spectrum occupation and enabling new metrics for the selection of channels used by this protocol. Keywords— WirelessHART; spectrum sensing; energy detection; automation systems.

متن کاملWirelessHART- Implementation and Evaluation on Wireless Sensors
The process automation industry is adopting wireless technologies, but in such harsh environments technologies like Bluetooth and ZigBee are not reliable enough. An alternative to Bluetooth and ZigBee is WirelessHART that can cope with the noisy environment but instead imposes very high demands on the hardware. We show that it is possible to run WirelessHART on sensor nodes with as little as 10...

Cooperative Spectrum Sensing (CSS) is an effective approach to overcome the impact of multi-path fading and shadowing issues. The reliability of CSS can be severely degraded under Byzantine attack, which may be caused by either malfunctioning sensing terminals or malicious nodes. Almost, the previous studies have not analyzed and considered the attack in their models. The present study introduc...
