Abstract(in English) Wireless communication technologies have started finding the industrial field applications steadily, where Wireless Sensor Network (WSN) is supposed to play a central role among others like the passive RFID or Wireless LAN systems. It is expected that the number of wireless sensor nodes proliferate beyond that of traditional wired deployment, because of their minimized initial infrastructural investments and the emerging instrumental wireless devices like an integrated sensors and actuators. For such steady and practical deployment of WSN, its robustness, reliability and outage free availability are inevitable characteristics to justify the adoption of WSN technologies as the industrial field systems. Consequently the diversity enhancement including MIMO technologies, sophisticated mesh networking mechanisms, and the comprehensive and optimized network architecture to achieve low power dissipation of leaf sensor nodes including an energy harvesting or scavenging devices, as well as adaptive frequency agility functions for efficient utilization of scarce frequency resource, have to be emphasized to fulfill the requirements. For these end, an infrastructural hierarchy architecture have been researched to solve contradicting requirements of, high reliability and availability even in the shadowing situations, minimized power dissipation at each leaf sensor nodes, managed co-channel interference to alleviate the throughput bottle neck in mesh traffic, and efficient usage of scarce frequency resources, based on the distinctive wireless propagation environments of industrial field.
