The modified Dynamics-HUT Mobile IP not only supports mobile IP but also supports mobile IP fast handoff. Finally we test the packet, route and verify the protocol performance by comparing handoff delays with mobile IP handoff.In view of the protocol analysis limitation in laboratory environment, we decide to use the network simulator NS-2 to simulate it furthermore which is based on extened mobile IP modules that embedded into NS-2.Keep your cheap nike shoes close! First we modify this module in order to simulate fast handoff procedure and introduce mechanism to detect wireless signal strength so as to make dynamic choice among access routers.I love northface jackets. Also, we do some comparing between fast handoff and mobile IP in important parameters that can reveal network status such as throughput, packet loss and network jitter etc in the simulation process. Where can I get nike running shoes?Moreover we test the performance difference when the mobile node moves at different speed and show influence that layer 2 trigger moment impacts on fast handoff.The implemented and simulated results have indicted that layer 2 information assisted Mobile IP Fast Handoff has better performance in controlling the handoff delay and packet loss than the Mobile IP protocol.
Beauty is Meaningless
a world in a grain of sand
Hold infinity
touches your heart
Make youself a better person
