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]
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]
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]
Pre-Authenticated Fast Handoff in a Public Wireless LAN Based on IEEE 802.1x Model
White Paper Multiple APs are selected using a Frequent Handoff Region (FHR) selection algorithm considering users' mobility patterns and their service classes. In the public wireless LAN network, since re-authentication latency during handoff affects the... [05 Dec 2007]
Simulation-Based Performance Comparison of TCP-Variants Over Mobile IPv6 Based Mobility Management Schemes
White Paper These IPv6-based mobility management schemes like MIPv6, HMIPv6 and Fast Handovers adversely affect the performance of transport protocols like TCP during handoff. Owing to explosive growth of wireless users and growing demand of wireless services... [30 Oct 2007]
High Mobility in a Realistic Wireless Environment: A Mobile IP Handoff Model for NS-2
White Paper Wireless technology has the great merit to allow users' mobility. Scenarios involving high mobility can be very complex; think, for instance, to a realistic case involving several nodes, representing people and cars moving under the coverage of... [30 Aug 2007]
Handling Client Mobility and Intermittent Connectivity in Mobile Web Accesses
White Paper The paper introduces the notion of eventual-delta consistency, and in the context of push and pull-based dissemination proposes buffering techniques at the proxy to mask the effects of client disconnections and application-level handoff algorithms... [30 Aug 2007]
A Simulation Environment for Analysis of QoS and Signaling Load in Mobile Cellular Networks
White Paper CELSA1 (Cellular Signaling Analyzer) is used for study of signaling load in mobile cellular networks, through the cost analysis of implemented procedures like power up, power down, call origination, handoff and location updating. [23 Aug 2007]
Route Recovery Mechanisms for Ad Hoc Networks Equipped With Switched Single Beam Antennas
White Paper In the event of a link failure, the optimized Directional Routing Protocol (DRP) proceeds in three phases to recover the route to the destination; antenna beam handoff; local route recovery; and zonal route recovery. [23 Aug 2007]

Hierarchical Handoff Schemes Over Wireless LAN/WAN Networks for Multimedia Applications
White Paper The paper makes use of a proposed hierarchical mobility management scheme to evaluate the performance of a handoff procedure with a hierarchy level of one. The objective of this paper is to study the performance of handoff procedures for an... [01 Aug 2007]
On Failure Recoverability of Client-Server Applications in Mobile Wireless Environments
White Paper Analytical results for the Cdf of the failure recovery time for client-server applications in mobile wireless environments characterized by logging, and mobility handoff strategies for facilitating failure recovery are reported in the paper. [20 Jul 2007]
Handoff Management Without Intercell Hard Handoffs in a Multifrequency CDMA System
White Paper This paper addresses handoff management in a multifrequency code-division multiple-access system with nonuniform traffic loads over cells. The paper proposes a new handoff scheme, called here adaptive handoff management (AHM), in which the inter... [21 Feb 2006]
