whitepaper In this paper, TCP HandOff (TCP-HO), a practical end-to-end mechanism, is proposed for improving TCP performance in heterogeneous mobile environments. In particular, TCP faces severe challenges when user moves around in these networks and handoff...

whitepaper This paper proposes a novel cell switching (e.g.packet handoff) scheme to support QoS guarantee for downlink in EGPRS (Enhanced General Packet Radio Service) network. The paper defines the new packets and handoff packets for each type of traffic...
[01 Aug 2007]
whitepaper In the proposed scheme, multiple paths are acquired during the handoff period. Multimedia application, such as stream media, will become very popular in future heterogeneous wireless networks. There are two main reasons that cause difficulties in...

whitepaper The next generation wireless networks will support the vertical handoff mechanism in which users can maintain the connections when they switch from one network to another (e.g.from IEEE 802.11b to CDMA 1xRTT network, and vice versa).
[19 May 2006]
whitepaper This paper presents an overview of the issues arising in such hybrid systems and international research work, with particular emphasis on Quality of Service (QoS) and vertical handoff. An outline of the research is presented, that is, optimising...

whitepaper This paper describes a first implementation of a policy based Mobile IP handoff decision (POLIMAND) which uses link layer parameters for MIP handoff decisions. There is currently a large variety of heterogeneous wireless access networks and...

whitepaper This paper considers optimizing the utilization of radio resources in a heterogeneous integrated system consisting of two different networks: a Wireless Local Area Network (WLAN) and a wideband Code Division Multiple Access (CDMA) network.
[07 Feb 2006]
whitepaper A major challenge in building 'all-IP' wireless access networks, besides the use of IP as the unifying layer, relates to transparency of the IP handoff process as the mobile node (MN) transits across heterogeneous wireless network domains in IP...

whitepaper candidate prediction of wireless LAN hotspots for location-based services over heterogeneous networks. The fast growing number of WLAN hotspots (restricted or unrestricted access) especially in densely populated cities may be able to provide the...

whitepaper Second, we discuss a reflective handoff’ service, which allows programmable mobile devices to freely roam between heterogeneous wireless access networks that support different legacy signaling systems.
[24 Feb 2004]
whitepaper Next, we discuss reflective handoff services’, which allow mobile devices to roam across heterogeneous access networks. First, we describe ‘multi-handoff access networks’, which are capable of simultaneously supporting multiple styles of handoff...
