Solving location problem of a mobile host by an agent group

An intelligent moving agent (IMA) group designed for a mobile host (MH) is presented. The concept of group communication, intelligence and moving code are introduced into the design of the IMA. By the operation of the IMA group, a MH can act as a computer on the wired network and the following goals can be achieved: (1) the MH on the wireless network can become a member on the internet; (2) the hand-off problem can be solved by the moving feature of an IMA; (3) the location problem can also be solved by introducing the concept of group communication among the IMAs, which resides on different base stations, serving the same MH; and (4) the reliability and bandwidth of wireless communication can be solved by the store and forward ability of the IMA.
