In this paper, we study the throughput and delay scaling laws of two coexisting mobile networks. By considering that both the primary and secondary networks are mobile and move according to random walk model, we propose a multi-hop transmission scheme. Based on the assumption that the secondary node can help to relay the primary packet, we show that the secondary network can achieve the same throughput...
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...
Terminal mobility support enables mobile terminals to switch from one wireless network to another wireless network without interrupting existing data connections. Existing protocols are designed for scenarios that the handover takes place between overlapping wireless networks. However, if a mobile terminal becomes disconnected for a while before it can join another network, existing protocols are...
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...
Mobile IP enables IP mobility support for mobile node (MN), but it suffers from triangular routing, packet redirecting, increase in IP header size, and the need for new infrastructure support. This paper details an alternative to enable terminal mobility support for MN. This scheme does not suffer from triangular routing effect and does not require dedicated infrastructure support such as home agent...
In this paper, we propose a mobility management scheme with quality-of-service(QoS) support for heterogeneous multihomed mobile node. With this scheme, the multihomed mobile node can move between networks seamlessly and at the same time, utilize all available links based on the QoS requirement. Session initiation protocol(SIP)[l] is used in session management and each multihomed node is identified...
Having multiple wireless interfaces in single multihomed mobile node provides some capabilities in term of path redundancy, load balancing, and available aggregate bandwidth. In this paper, we propose a scheme for mobility management to enable cooperation of multiple wireless interfaces by taking into account the quality of service (QoS) parameters both from network and application. This scheme support...
Mobility management has been an important focus in recent years due to the growth of mobile users. Besides mobile IP (MIP) standard, there are many proposals for mobility support in the literatures such as application mobility using session initiation protocol (SIP) [1] and terminal-assisted mobility [2]. With the availability of many wireless access technologies, vertical mobility becomes an important...
In network mobility support for wireless ad hoc networks, mobile routers (MRs) are connected to access router (AR) by ad hoc routing. Mobile network nodes (MNNs) connect to an MR to communicate to distant correspondent nodes (CNs). Previous works on network mobility in mobile IPv6 involve packet redirection through a home agent; this redirection is costly in both bandwidth and delay. In this paper,...
