With the development of wireless communication technologies, the mobile terminal can be installed with more than one wireless interfaces to support its flexible roaming and vertical handover between heterogeneous access networks. Traditionally, the ongoing session has to be re-established when the multi-interface terminal hands over vertically while maintaining the Delay Tolerant Networking (DTN)...
Hierarchical Mobile IPv6 (HMIPv6) is designed to reduce the handover latency and signaling load of Mobile IPv6 (MIPv6). However, HMIPv6 only improves local mobility performance while the handover latency in the inter-Mobility Anchor Point (MAP) handover is still long and packet transmission cost is still heavy due to the overlapped tunnels. In this paper, we propose a cascaded tunnel scheme in HMIPv6...
The Publish-Subscribe Internet Technology (PURSUIT) project aims at developing a new internetworking architecture for the Future Internet. The internetworking architecture of PURSUIT has adopted a Publish-Subscribe Internet (PSI) architecture that is one of the most promising approaches to solve the current Internet's limitations including mobility support. In this paper, a new mobility support scheme...
In this paper, mobile multicast mechanism based on IEEE 802.21 MIH (Media Independent Handover) for efficient network resource usage is proposed. Proposed mechanism supports the efficiency of network resource usage and fast multicast handover. The proposed architecture adopts multicast manager concept to MIH framework in order to efficiently perform mobile multicast handover, and adds the new MIH...
In this paper fast mobile multicast mechanism based on IEEE 802.21 MIH (Media Independent Handover) is proposed. We solve long multicast handover delay time caused by L3 movement detection mechanism of the existing mobile multicast methods. The proposed architecture adopts multicast manager concept to MIH framework in order to efficiently perform mobile multicast handover, and adds the new MIH messages...
This paper proposes a primary path switching scheme for SCTP handover, in which a mobile terminal switches its primary path to an alternate path adaptively by using the round trip times (RTTs) of the paths measured in the network. From the experiments we see that a conservative switching scheme is preferred in the network where the gap of RTTs of the candidate paths is small, whereas an aggressive...
