ordered field

We give a new definition of the so-called ordered field which is equivalent to the traditional one, and derive a series of the basic propositions with this new definition.

This paper bring out an approach of MTORM , which achieves the atomicity and total ordering properties of mobile group multicast communications.

为了实现移动组多播的原子性和全序性,提出MTORM方法,原子性用于保证多播消息能够最终传递到移动组内的所有移动Agent,全序性则保证任意一对多播消息都按照相同顺序被所有组内移动Agent传递。
