Wireless communication that provides voice only is not sufficient to support the necessity of user. It is an important feature of next generation wireless communication to offer this capability through mobile Internet. Mobile IP allows mobile hosts to change their location and reduce the losing probability of data packets in wireless communication networks. However, mobile IP still have some defects in handoff and route aspects. Therefore, cellular IP protocol is proposed for routing of IP diagrams to mobile stations and fast handoff control in a limited geographical area. It can cooperate with mobile IP to provide wide area mobility support. In this paper, a handoff method is proposed to improve Quality of Service and resource switchingmanagement to reduce data packet loss for mobile multimedia communication in cellular IP and mobile IP network.
