Locating in cellular mobile Internet of mobile hosts

Internetworking protocols such as IP currently do not allow "mobile hosts" to interoperate easily or conveniently with other hosts on the network. The Mobile IP Working Group of the Internet Engineering Task Force (IETF) has been working over the past few years to develop standard protocols to support mobile hosts operating in the Internet. Locating in mobile Internet of mobile hosts is an important part in this protocol. This paper describes the infrastructure and the locating method named "agent discovery" of the Mobile IP protocol. When locating hosts in the cellular mobile Internet using "agent discovery", the "vibrating registration" problem may arise. To solve this problem, we present a new method named "addresses sliding window". The main idea of this method and a detailed example is given.
