Simulation of MobileIP with MobiWAN

چکیده مقاله

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 [5]. But, some of these introduced mechanisms suffer from the lack of proper efficiency. One of these mechanisms is triangle routing. In this method; packets are routed to the home network of MN and then tunneled to Mobile Node (MN) by Home Agent (HA) [1]. This indirect routing is far from optimal, because of the existence of great delay in delivery of the packets to MN. Route optimization is a protocol to overcome delay in triangle routing. In route optimization, MN informs Correspondent Node (CN) with its current location and then, the packets are directly sent to MN by correspondent node [1], [4]. In this simulation, we have compared linear and star topologies with & without route optimization. We have used Network Simulator (NS) and MobiWan, to verify simulation results [2], [3].
