Wireless Sensor Networks for Industrial Process

S in radio and embedded systems have enabled the proliferation of wireless sensor networks Wireless sensor networks are tremendously being used in different environments to perform various monitoring tasks such as search, rescue, disaster relief, target tracking and a number of tasks in smart environments. In many such tasks, node localization is inherently one of the system parameters. Node localization is required to report the origin of events, assist group querying of sensors, routing and to answer questions on the network coverage. One of the fundamental challenges in wireless sensor network is node localization. This paper provides a survey on implementing wireless sensor network (WSN) technology on industrial process monitoring and control. First, the existing industrial applications are explored, following with a review of the advantages o WSN technology for industrial control. Then, challenging factors influencing the design and acceptance of WSNs in the process control world are outlined, and the state-of-the-art research efforts and industrial solutions are provided ng to each factor. Further research issues for the realization and improvement of wireless sensor network technology on process industry are also mentioned. This paper also reviews different approaches of node localization discovery in wireless sensor networks. The overview
