Coexistence aware for WirelessHART networks

Wireless sensor networks have been expanding rapidly in many applications for different areas such as residential, office and industrial. Wireless connections bring many advantages as installation feasibility, scalability, mobility and reduce infrastructure costs. However, wireless network performance is affected by many factors as, for example, environment characteristics and other wireless communication technologies at the same coverage area. The wireless communication resources are limited and many times shared, allowing interferences from different kind of electromagnetic sources. This work presents a thesis proposal for the investigation and development of adaptive methods for an industrial wireless network, the WirelessHART protocol. Through dynamic mechanism for spectrum sensing, channel selection and power control between devices communication is intended to increase the robustness and performance of the protocol.
