Route Navigation System in ZigBee-Based Sensor Networks

During the research of supplementary system for visual impairment people, it has been discovered that it is better to use ZigBee wireless technology considering the reliability, portability and flexibility. Through the independent regionally-covered Zigbee networks and the Zigbee terminal with voice prompts, clients will be able to get to the destination correctly and independently according to the data which has been inputted in advance. At the same time, the Zigbee networks will be connected to the local signal system in order to ensure clients´ security on their way to the destination. This project has been experimented with the help of simulation platform and proved effective in solving the problem about the clients´ security to a large extent.
