Analysis and design of real-time and reliable industrial wireless control communication network and protocol

Wireless communication technologies can bring great benefits to industrial automation systems. But because of the high data losses and transmission errors caused by channel fading and interferences, the hard real-time and reliability requirements of industrial automatic control are difficult to be guaranteed. An industrial wireless control communication network and protocol is put forward. The functions of each protocol layer are introduced. Service differentiating, resource reserving and cross-layer and cross-network schedule mapping mechanisms are used to provide the real-time and reliable communications. The performance analysis shows it can satisfy the requirements of industrial field monitoring and control.
