Recent initiatives to add mobility to the Internet are being considered by emerging mobile service providers as possible candidate solutions for the delivery of IP(Internet protocol) data to mobile users.Mobile IP is thus a solution for mobility on the global Internet which is simple

scalable

but there are some problems necessary to be solved.Route optimization techniques make extensions to the base Mobile IP protocol to improve the network performance.In this paper

both schemes have been analyzed and simulated.The results show that the performances in terms of throughput rate as well as end to end delay largely depend on the offered traffic pattern.Furthermore

both protocols can't support frequent handoff in future micro cell environment.
