Mobility support in IPv6 networks (MIPv6) and Fast Handovers for Mobile IPv6 (FMIPv6) are already released as RFCs for many years. While the former focuses on maintaining the network connections when a mobile node handovers across subnets, the latter is built based on the former concept, but focuses on reducing the packet loss and latency inherent to the handover process. Performance study of both...
IPv6 draws the great attention of important research institution and company, which has great advantage of enlarging address space, improving whole throughput of network, improving service quality, guaranteeing security, sustaining plug and play, sustaining mobility and better supporting multicast function. In this paper, the main purpose is to introduce the related contents of next generation internet,...
A wireless connectivity island is a geographic area covered by a particular wireless ISP. Nowadays, mobile users possessing multi-homing mobile devices can have IP-connectivity almost everywhere, while being on the move. In terms of vertical handover, these users jump from a connectivity island to another that could differ by communication technology, access provider, QoS conditions and price. The...
This paper presents a mechanism to evaluate fault-tolerant WiFi network performance in a mobile environment. Fault-tolerance at the access point (AP) level is presented in a degraded performance mode. In case of an access point (AP) failure the surrounding APs increase their power to compensate for this failure. Mobile IPv6 is used as mobile protocol for the moving entities. A new metric is introduced...
