Design of Physical Layer and MAC Layer of ZigBee Protocol Based on Embedded Real-Time Operating System

This paper researches on wireless sensor network based on Embedded Real-Time Operating System.In analyzing RTOS and wireless sensor networks,a software design methods on physical and MAC layer of ZigBee is presented based on a micro-kernel embedded real-time operating system.This method reduced the difficulty of the wireless network development by programs expansion and codes migration.It provides a simple and easy to realize platform for the subsequent network layer and application layer development.
