Abstract
ABSTRACT Mobile IPv4 is designed to allow the mobile nodes to have internet connectivity without changing their IP addresses while roaming between other networks. The packets sent from Correspondent Node (CN) to a Mobile Node (MN) through the mobile node’s Home Agent (HA), then the HA forward them to the MN’s foreign network. One of the main problems that faced the original Mobile IP is the triangle routing problem. Triangle routing problem appears when the indirect path between CN and MN through the HA. The path is longer than the direct path. This paper proposes a new technique to improve the performance of the original Mobile IP by reducing the average delay and packet loss for all the packets transferred between the CN and the MN. In this technique, the packets will delivered to MN directly without passing by HA, and they will pauses in tunneling buffer till MN reach to new network and receive new address. To show the effectiveness of the proposed technique, it is compared with the original Mobile IP and another technique that try to solve the same problem. The simulation of the original Mobile IP and new technique is carried out using NS-2 simulator on Linux platform. The simulation results show that the proposed technique is more effective than the original Mobile IP and others.
