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]
Dynamic GOP Structure Selection to Support QoS in Vertical Handoff
White Paper This paper proposes a dynamic GOP structure selection method to provide seamless video streaming for vertical handoff in the heterogeneous wireless network. Thus, with the proposed method, the client can always receive the I-picture right after... [18 Jul 2008]
Scalable Real-Time Gateway Assignment in Mobile Mesh Networks
White Paper In particular, in a large WMN, the dynamic assignment of users to Internet gateways will become a complex traffic engineering problem that will need to consider load peaks, user mobility, and handoff penalties. [18 Jul 2008]
A Dynamic Load Balancing in Wireless CDMA Cellular Networks
White Paper The load balancing problem is formulated as an integer linear program which minimizes the unserved traffics and handoff calls in the network. With the increase of cellular users the traffic hot spots and unbalanced call distributions are common in... [10 Jul 2008]
Soft Handoff and Uplink Capacity in a Two-Tier CDMA System
White Paper In systems using Code-Division Multiple Access (CDMA), user capacity is enhanced by using soft handoff. Soft handoff means that a given user communicates simultaneously with two or more base stations until its path gain to just one of them is... [24 Mar 2008]
Impact of Soft Handoff on TCP Throughput Over CDMA Wireless Cellular Networks
White Paper In CDMA cellular networks, the soft handoff technique allows a mobile host to communicate with multiple base stations simultaneously, improving the transmission quality of the wireless channel and avoiding disconnection upon to base station... [14 Jan 2008]
An Enhanced Handoff Mechanism for Cellular IP
White Paper Handoff is one of the most important factors that may degrade the performance of TCP connections in wireless data networks. This paper presents a lossless and duplication free handoff scheme called LPM (Last Packet Marking) for improving Cellular... [14 Jan 2008]
Performance Analysis of Optimized Smooth Handoff in Mobile IP
White Paper In order to reduce more the packet losses during handoff, new schemes have been defined, such as smooth handoff. Mobile IP allows node mobility involving changes of point-of-attachment to the Internet. [14 Jan 2008]
Performance Improvement by Packet Buffering in Mobile IP Based Networks
White Paper The simulation result shows that in most cases, the smooth handoff by the route optimization extension of Mobile IP standard cannot prevent the degradation of TCP performance due to handoffs, although it is designed to reduce the number of packets... [14 Jan 2008]
TCP Performance Enhancement by Implicit Priority Forwarding (IPF) Packet Buffering Scheme for Mobile IP Based Networks
White Paper Smooth handoff by the route optimization extension of Mobile IP standard should support packet buffering mechanism at a Base Station (BS) in order to prevent TCP performance degradation due to packet losses in mobile networks environment. [14 Jan 2008]
Link Layer-Based TCP Optimisation for Disconnecting Networks
White Paper Network disconnections are encountered in many scenarios, including being out-of-range in a wireless network, during network handoff, and also in the case of Networked Surfaces, a novel LAN technology which provides the motivation for this work. [14 Jan 2008]
TCP HandOff: A Practical TCP Enhancement for Heterogeneous Mobile Environments
White Paper In particular, TCP faces severe challenges when user moves around in these networks and handoff occurs frequently. In this paper, TCP HandOff (TCP-HO), a practical end-to-end mechanism, is proposed for improving TCP performance in heterogeneous... [08 Jan 2008]
Adding Network-Layer Intelligence to Mobile Receivers for Solving Spurious TCP Timeout During Vertical Handoff
White Paper With the help of Mobile IP/IPv6 and soft handoff, on-going TCP sessions can remain active and handoff packet loss can be avoided. However, TCP still faces several performance degradation issues due to the disparities in bandwidth and propagation... [08 Jan 2008]
A New Prioritized Fast Handoff Protocol for Mobile IP
White Paper However, Mobile IP suffers from handoff latency due to slow handoff discovery and binding association notification. To reduce this latency, the paper proposes a new handoff protocol where it attributes a high priority to registration request... [26 Dec 2007]
Connection Handoff Policies for TCP Offload Network Interfaces
White Paper This paper presents three policies for effectively utilizing TCP offload network interfaces that support connection handoff. These policies allow connection handoff to reduce the computation and memory bandwidth requirements for packet processing... [19 Dec 2007]
