“…The MIP user should perform registration procedure whenever it moves to a new Access Router (AR)'s domain (i.e., a domain is managed by an AR) even when it is idle, and this unnecessary location updates cause the significant waste of resources and battery power consumption [1,7,8]. Thus, there have been many IP paging techniques for MIP where idle MNs can move across different subnets in a paging area without the registration procedure with the aim to reduce the unnecessary location update [9][10][11][12][13][14][15]. The same problem can also be observed in PMIPv6 networks: proxyregistrations are still performed for MNs in idle mode, resulting in unnecessary signaling traffic in the PMIPv6 network.…”

Moreover, data traffic for MNs should be also managed by the mobility entities in the network-based mobility management architecture, resulting in lack of the network resource and limitation of the scalability in support of a large number of MNs [11,16].

In Proxy Mobile IP (PMIPv6) networks, proxyregistrations are performed even for idle MNs, resulting in unnecessary signaling traffic. Although there have been many IP paging techniques aimed at reducing the unnecessary location update, they focus only on Mobile IP (MIP) since they had been developed before PMIPv6 was proposed. Thus, adopting existing IP paging support is not sufficient to support mobility in PMIPv6 networks. For more efficient support, we propose a dynamic multi-step paging scheme that pages an MN in multiple incremental steps instead of flooding paging messages to a whole paging area to significantly reduce the signaling traffic caused by the proxy location updates in the PMIPv6 networks. In addition, to improve the paging delay performance that may be deteriorated by the multi-step paging, the proposed scheme configures paging area dynamically to raise the efficiency of locating MNs. The size of a paging area is designed to be determined based on the speed of an MN. We also develop a thorough analytical model for evaluating the performance of the proposed scheme compared with a static paging scheme in terms of the signaling cost and the paging delay. Thorough analysis and simulation demonstrate that in the PMIPv6 network, our paging scheme can significantly reduce the signaling cost for IP paging, achieving a shorter paging delay, compared to that of a paging scheme with a fixed paging area.

“…Thus, UMS also has less traffic overhead than proposals such as [14] which is based on mobile IP. Since triangular routing is not used by UMS, the traffic overhead generated by UMS is thus also less compared to proposals such as [13] and [15], which need triangular routing for packet redirection . By using the virtual interface and the permanent address, UMS completely hides the heterogeneity of the physical interfaces and decouples the node identifier and node locator.…”

Mobility management and multihoming in heterogeneous networks

Heterogeneous networks become popular nowadays with wireless technologies such as WiMax, 3G/UMTS, WiFi, in which all could be deployed in a single device. The combination of multiple interfaces enables mobile devices to use either one or all of the interfaces at the same time. However, the support for mobility raises new issues not only in handoff management but also in the quality of service (QoS). Various research works have focused on how to manage QoS requirements in heterogeneous networks where delay sensitive real-time applications need low delay-tolerance and high bandwidth links. A novel framework to support mobility in heterogeneous network for multihomed devices with QoS support is proposed. Based on a cross-layer handoff approach, we make use of SIP protocol to ensure seamless connection during handover across networks. The solution employs multiple interfaces to take advantage of the multihoming capability of the device thus enhances QoS support for data transfer, especially in multimedia streaming. Unlike many current proposals, the framework can support both UDP and TCP transmissions where UDP is less reliable while TCP incurs extra delay and overhead. The framework has been implemented in a testbed. Experimental results collected from real-time streaming show that the framework can provide seamless mobility support and optimized flow distribution for heterogeneous multihomed mobile nodes. The seamless mobility idea is further extended. An application framework to support seamless handoff between 3G/UMTS and WLAN for VoIP applications on the Symbian iii ATTENTION: The Singapore Copyright Act applies to the use of this document. Nanyang Technological University Library platform is proposed. VoIP applications require high quality and low latency transmissions. Unlike other approaches, the proposed framework lies in the application layer of the mobile devices and hence does not require a change in network infrastructure. Neither is modification required in the kernel layer. Hence it is portable among mobile devices and is easily customized for different VoIP systems. We further apply the multihoming concept to Delay Tolerant Networks (DTN) and modify the DTN routing protocol MaxProp to exploit multiple network interfaces. Simulation results show that the multihomed MaxProp improves delivery rate and reduces message latency compared to the original MaxProp. The improvement is even more prominent when buffer space is limited in the DTN node. The DTN simulator, ONE (Opportunistic Network Environment) has also been modified to support the simulation of DTN with multiple interfaces.
