The Design and Realization of Senor Networks Node EOS
一个传感器网络结点EOS的设计与实现

In the recent year,development of embedded technology and wireless networks provides probability to reali- zation of sensor networks.The nodes of sensor networks is a computer system based on embedded devices whose re- quest is strict with function,reliability,cost,volume,power.So to design a kind of kernel of operating system aiming at sensor networks node is an urgent problem in the field.In this paper,particularity and diversity of tasks of sensor net- works node was analyzed at first,and then a common real-time operating system kernel of sensor networks node (SNNEOS)was put forward.At last,its some key problems such as its structure,its management of kernel interrupt and its communications subsystem were discussed.
