Eliminating the State of Ping-Pong for Mobile IP Optimization

Abstract

Mobile internet protocol, an extensionprotocol for wireless networks, provides extra ability for the mobile nodes to roam without any loss of connectivity at the network-layer. During the movement of a mobile node, when the node comes within the coverage range of more than one access points, the node starts fluctuating between the attachment points back and forth and results in frequent handovers. Frequent handovers in overlapping cells causes the ping-pong effect, which produce unacceptable additional switching overheads and degenerate the overall performance of the network. We propose an algorithm, of the original internet protocol for wireless networks, provides extra ability for the mobile nodes to roam without any loss of connectivity at the network-layer. During the movement of a mobile node, when the node comes within the coverage range of more than one access points, the node starts fluctuating between the attachment points back and forth and results in frequent handovers. Frequent handovers in overlapping cells causes the ping-pong effect, which produce unacceptable additional switching overheads and degenerate the overall performance of the network. We propose an algorithm, called eliminated ping-pong state, in order to equip mobile nodes with an ability to detect the state of ping-pong that consequently reduces needless recurrent handovers to improve the network performance. Our evaluation shows that the proposed algorithm upturns the network throughput and shows notable reduction in network delay and packet loss.
