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]
Selective Channel Scanning for Fast Handoff in Wireless LAN Using Neighbor Graph
White Paper 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]
Load Balancing in Overlapping Wireless LAN Cells
White Paper Overloaded access points force the handoff of some stations to balance the load. The paper shows via experimental evaluation that the balancing scheme increases the total wireless network throughput and decreases the cell delay. [05 Dec 2007]
Performance Evaluation of Layer 3 Low Latency Handoff Mechanisms
White Paper This paper investigates the performance of two Layer 3 low latency handoff protocols proposed by the IETF, namely Pre- and Post-Registration. The paper describes several handoff implementations over a wireless access based on the IEEE 802.11... [08 Aug 2007]
Position Leverage Smooth Handover Algorithm for Mobile IP
