Simulation and evaluation of mobile IPv6

Mobile IP is a protocol to support the mobility of a host, changing its point of attachment to the Internet. This protocol introduces different mechanisms, to successfully route packets destined to the mobile node. One of these mechanisms is triangle routing. Route optimization (RO) is a protocol to overcome delay in triangle routing. In RO, the mobile node (MN) informs the correspondent node (CN) with its current location and then the packets are directly sent to the MN by the CN. In this simulation, we have compared linear and star topologies with and without RO. The topology model has important effects on the results. The GT-ITM model has been used for having a better judgment on the performance of RO. We found that jitter is not just the function of route optimization. The structure of the topology also has some important effects on it. Finally, we concluded that RO strategies in a star topology reduces jitter, but the same strategies in a linear model increase jitter. Note that RO improves delay, regardless of the topology used.
