DiffServ QoS Provisioning for Real Time Traffic in Frequent Handoff MobileIPv6 Networks
White Paper Two major challenges in establishing such a wireless mobile Internet are support of fast handoff and provision of Quality of Service (QoS) over IP-based wireless access networks. The use of DiffServ eliminates the signaling overhead on mobile node... [18 Jul 2008]
Pre-Authenticated Fast Handoff in a Public Wireless LAN Based on IEEE 802.1x Model
White Paper In the public wireless LAN network, since re-authentication latency during handoff affects the service quality of multimedia applications, minimizing authentication latency is very important in order to support real-time multimedia applications on... [05 Dec 2007]
Hierarchical Handoff Schemes Over Wireless LAN/WAN Networks for Multimedia Applications
White Paper The objective of this paper is to study the performance of handoff procedures for an integrated wireless LAN/WAN infrastructure, both qualitatively and quantitatively. The paper makes use of a proposed hierarchical mobility management scheme to... [01 Aug 2007]
Priority-Determined Multiclass Handoff Scheme With Guaranteed Mobile QoS in Wireless Multimedia Networks
White Paper In multimedia cellular networks, one should not only minimize the dropping rate of handoff calls, but also control the blocking rate of new calls at an acceptable level. This paper proposes a novel multiclass call-admission-control mechanism that... [01 Aug 2007]
Performance Analysis of Cell Switching Management Scheme in Wireless Packet Communications
White Paper 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]

Smooth Handoff Scheme for Stream Media With Bandwidth Disparity in Wireless Cells
White Paper 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... [01 Aug 2007]
Optimal Joint Session Admission Control in Integrated WLAN and CDMA Cellular Networks With Vertical Handoff
White Paper The paper proposes a joint session admission control scheme for multimedia traffic that maximizes overall network revenue with Quality of Service (QoS) constraints over both the WLAN and the CDMA cellular network. [07 Feb 2006]
Effect of Mobile Station's Speed on Vertical Handoff Detection Delay
White Paper Using a WLAN-GPRS hybrid network model, the effect of mobile station's speed on vertical handoff detection delay is analysed, through simulation and mathematical approaches. WLAN technology is expected to complement cellular wide area technology... [21 Nov 2005]
QOS-aware Middleware for Mobile Multimedia Communications
White Paper Mobiware provides value-added QOS support by allowing mobile multimedia applications to operate transparently during handoff and periods of persistent QOS fluctuation. To address this challenge we are developing mobiware, a QOS-aware middleware... [24 Feb 2004]
