As a mobile node switches from one subnet to another, Mobile IPv6 requires that it authenticate the new care of address of the new subnet with the corresponding node. The authentication process, called return routability (RR) test, is required in every handoff and can delay the handoff process by a round trip delay between mobile and corresponding nodes. In this paper, two mechanisms are proposed...
Since IPv6 is designed for fixed hosts, the extension of IPv6 to mobile IPv6 is necessary for management in mobile and wireless environment. In this paper, we present an assessment of current mobile IPv6 performance by the means of the network simulator ns-2 and its extension MOBIWAN. Three different tests have been carried out with different traffic types on different network topologies. We investigate...
Control signaling messages in mobile IPv6 are mainly used to inform the home agent (HA) and the correspondent node (CN) about the mobile node's (MN's) new address when its network attachment point is changed. In order to prevent various attacks, such as man-in-the-middle and denial-of-service attacks, these messages must be protected. Protocols based on Identity-Based Encryption (IBE) for protecting...
This study presents a novel embedded WiMAX-based vehicular router with a network mobility architecture that promotes the telematics services for ubiquitous/pervasive computing (UPC) environment anytime and anywhere. Each telematics user has to process the handoff procedure with the mobile IP mechanism. Therefore, the proposed WiMAX-based vehicular router can process more Telematics users for handoff...
The optimization of the handover, which can minimize the handover delay and packet loss rate, is an indispensable technology in MIPv6. In this paper, a low-latency and smooth handover optimization scheme is proposed based on two main factors affecting the handover performance: duplicate address detection and binding update. A mode of duplicate address detection is introduced, in which the access router...
Mobile IPv6 supports a global mobility solution in wireless networks. The mobile node is unable to send or receive packets during handover, due to link switching delay and IP protocol operations. This handover latency is caused by standard mobile IPv6 procedures, such as movement detection, new care of address configuration, and binding update. This configuration is the most time-consuming phase,...
This paper proposes a novel secure binding management protocol for mobile IPv6 networks for use in the implementation of routing optimization. The idea uses the public key of the home network of a mobile node to cryptographically generate the mobile node's home address and the associated private key to sign the mobile node's authentication requests. In addition, the proposed protocol performs reachability...
This paper proposes an extension to Fast-handover Mobile IPv6 [6] that improves handover latency in Mobile IPv6 procedures in case mobile nodes have multiple wireless interfaces. In the basic Fast MIPv6 [6], a previous access router (PAR) forwards arriving packets for the mobile node to a new access router (NAR) by setting up a tunnel to the NAR in order to prevent packet losses incurred by latency...
