Design And Implement Of Wireless Ad Hoc Network Communication Module Based On ZigBee Technology

Recently, with the rapid development of electronic technology and network technology, wireless network has been a hot topic. In the field of intellective family and industrial control, people urgently hope to produce a wireless, short-distance, low-speed, low-energy network. ZigBee is such a new short-distance, low-speed wireless network technology, which is a technology solution between Wireless Markup technology and Bluetooth technology. ZigBee is based on IEEE 802.15.4, which is a standard of IEEE wireless personal area workgroup, is called IEEE 802.15.4 technology standard.This article first introduces ZigBee wireless communication technology, analyzes the theory, character, merits of this technology and the limitation of applications. In the Inner and Outer of the country part, I introduce the performance instances in the application filed and productions. The above contents indicate the feasibility and dependability while replace serial ports, parallel ports and data cable by ZigBee device in the wearable computer component usage, and the feasible solution of the software and hardware implementation. And then we analyze the module, the contents and functions on each layer, and the roles they play during the performance. Based on the previous research and analyses, this article briefly describes the performance mechanism of the protocol stack, defines the logical construct of each layer in the design in details, and the interface definitions between the layers,then introduce the data frame formate of each layer of the improved protocol, the performance flow of data management functions. Finally we simulate the design and check the effects.This article purpose implementing the wireless connection among the wearable computer components, the employ of ZigBee technology will effectively reduce the cost of hardware perchase, software development, complexity and the consume of energy, it will also provide wearable computer with wide space for applications and further development, which provides practice meanings and application value.
