In a wireless domain where a mobile user accesses heterogeneous wireless technologies with multiple interfaces, a multi-path scheduling algorithm can benefit mobile users' experience by aggregating different network bandwidth together. However, existing literature actually shows that for TCP flows, it may not be the case. To better exploit multi-path scheduling for TCP connections, this paper presents...
Rapid development has equipped mobile devices with heterogeneous wireless access capabilities. A lot of work has been done on WLAN-3G integration to support seamless connectivity and global roaming. Most recent research trends focus on interwork gateway or intersystem roaming framework. In this paper, we introduce an application framework providing seamless connectivity for mobile devices across heterogeneous...
In recent years, a lot of terminal mobility support schemes have been proposed. These schemes mainly focus on providing seamless mobility by reducing the handover delay. They work well when the handover takes place between two overlapping wireless networks. However, in some worst scenario, it is possible that a mobile node (MN) becomes disconnected from the network for some time before it can join...
As a local mobility management protocol, Proxy Mobile IPv6 (PMIPv6) is designed to enable mobile nodes to move in a domain without any involvement in the mobility signalling operation. However, a single domain cannot satisfy mobile nodes' movement requirement. Hence, we propose a solution to enable mobile nodes to move across multiple PMIPv6 domains. We introduce a new network entity called traffic...
To improve the local mobility performance of a wireless network, we present a new framework, namely Efficient Framework for Local Mobility (EFLoM). In EFLoM, we introduce three entities: Local Anchor Router (LAR), Wireless Access Gateway (WAG) and Mobile Node (MN). LAR is a router that is in charge of MN's IP mobility management. It keeps track of MN's movement, and delivers the MN's packets to its...
