whitepaper 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...

whitepaper 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...

whitepaper 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...

whitepaper 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]
whitepaper 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...

whitepaper 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.

whitepaper 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]
whitepaper 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]
whitepaper 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]
whitepaper 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]
whitepaper 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]
whitepaper This paper presents a connection handoff interface between the operating system and the network interface. Using handoff, the operating system controls the number of offloaded connections in order to fully utilize the network interface without...
[19 Dec 2007]
whitepaper This paper presents the design and implementation of Split-Stack, a novel and efficient mechanism for handing off TCP connections that enables fine-grain load balancing among the servers of a cluster.
[19 Dec 2007]
whitepaper There are two causes of packet loss in a wireless environment; they are corruption and handoff loss. In this paper, an extension for the earlier work has been proposed by the authors in order to recognise handoff loss.
[05 Dec 2007]
whitepaper 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]
whitepaper Handoff at the link layer 2 (L2) consists of three phases including scanning, authentication, and reassociation. In this paper, based on the Neighbor Graph (NG), the paper introduces a selective channel scanning method with unicast for fast handoff...
[05 Dec 2007]
whitepaper The growing popularity of IEEE 802.11 has made wireless LAN a potential candidate technology for providing high speed wireless access services. Also, by supporting Mobile IP, wireless LAN can meet demands for expanded wireless access coverage while...
[05 Dec 2007]
whitepaper In such a case, avoiding performance degradation during the handoff becomes a critical issue. The majority of existing studies deal with handoff decisions based on upper layer information such as packet loss, but none of the studies extensively...
[05 Dec 2007]
whitepaper The paper developed subnet-based direct tunneling techniques to improve the routing efficiency for mobile IP and a binding optimization technique to reduce the handoff latency for mobile nodes. This paper proposes to support symmetric bidirectional...
[05 Dec 2007]
whitepaper Overloaded access points force the handoff of some stations to balance the load. This paper proposes a load-balancing scheme for overlapping wireless LAN cells. Agents running in each access point broadcast periodically the local load level via the...
