基于ISA100.11a协议的终端设计及隧道传输方法
Endpoint Design and Tunnel Transmission Method Based on ISA100.11a Protocol
摘要
Abstract
For Wireless Sensor Network (WSN) protocol with complicated communication mechanism and abundant supported function as ISA100.11a,traditional design of endpoint based on embedded single chip computer system is hardly to meet practical requirements.Hence,a design of endpoint in which the User Application Process (UAP) is separated from other protocols is proposed.Combining the object oriented structure of the application layer of ISA100.11a protocol,the user application processes and specific I/O interfaces of the application layer are defined as the application module,and the other parts of the protocol are defined as the communication module.One side,limited resource of single chip is no longer needed to deal with application and communication functions simultaneously to avoid bottleneck of performance.On the other side,flexible and extensible I/O interfaces which can be collected and managed are provided,then on this basis the tunnel transmission function in the ISA100.11a protocol which can be compatible with data from outer protocols can be implemented more conveniently.Experimental results show that the design can reduce the rate of packet missing of the whole WSN system efficiently,and provide compatible capacity of data from outer protocols such as ZigBee.关键词
