RESUMO
In mobile IP networks, a connection of transport established with a mobile device may be interrupted due to a possible exchange of IP addresses caused by a change of network. The period between the moment when device realizes that the network is changing - time in which begins the process of changing its IP address - until the moment that it restores all connections with other devices is called period of handoff, and this period is called the latency of handoff . Some protocols specifications allow us to remain accessible while mobile move in IPv6 network, as the MIPv6 (Mobility for IPv6). But even with the use of MIPv6, during the handoff, exchanged packages with the mobile device could be delayed more than desired or even be lost. This effect diminish the quality of communication, especially when it is dealing with multimedia data. The focus of this work is the implementation of the Protocol Host Identity Protocol (HIP) in a tool for simulation to evaluate the protocol with the goal of establishing, quantitative way, the impact of disruption and restoration of communication in mobile environments. The proposed protocol ensures the mobility using a new identity for the hosts that is independent IP address. The latency and loss of packages are studied, by simulation, during the handoff of HIP protocol in order to justify further investigation.
