“…To reach this goal the handover delay needs to be minimized. In [11] it is shown through analytical modelling that using Media Independent Handover (MIH) can greatly improve the handover delay of PMIPv6 networks. The paper does however not cover fast handover situations with multicast.…”

Abstract. There is a demand in the Public Protection and Disaster Relief (PPDR) community for high bandwidth services on mobile devices. Group communication is an important aspect of PPDR networks. In IP based networks multicast is the preferred method to efficiently transmit data to more than one receiver simultaneously. It is important PPDR users can switch seamlessly between wireless networks. This paper describes improvements to multicast in Fast handovers for Proxy Mobile IPv6 (PFMIPv6) to provide seamless mobility to its users. We also identify and explore the specific problems stemming from difference in end-to-end delay between the old and new path during handovers for multicast traffic. A novel mechanism to determine the delay difference between two paths in a PFMIPv6 system is described and an implementation of this system is evaluated. It is shown the proposed approach can prevent multicast packet loss during a handover.

“…Rather, it provides tools to exchange events, information and commands in order to initiate handover execution that can be done using some handover execution protocol. On the basis of this, solutions for vertical handover management can be developed (e.g [11][12]).…”

Abstract: The problem of efficient use of resources in wireless access networks becomes critical today with users expecting continuous high-speed network access. While access network capacity continues to increase, simultaneous operation of multiple wireless access networks presents an opportunity to increase the data rates available to end-users even further using intelligent cross-network resource sharing. This paper introduces a new Integrated Mobility and Resource Management (IMRM) framework for automatic execution of policies for cross-network resource sharing using traffic offload and pre-emptive resource reservation algorithms. The presented framework enables both mobile-initiated and network-initiated resource sharing policies to be executed. This paper presents the framework in detail and analyses its performance using extensive ns-2 simulations of the operation of a set of static policies based on measured signal strength, and dynamic pre-emptive network-initiated policies in a WiFi/WiMAX scenario. The detailed evaluation of the static policies clearly shows that the quality of voice applications shows large deviation, mostly due to very different levels of delay in access networks. Based on these conclusions, this paper presents a design of two new dynamic policies and shows that such policies, when efficiently implemented using the new IMRM framework can greatly improve the capacity of the network to serve voice traffic with a minimal impact on the data traffic and with a very low signalling overhead.

The interworking and interoperation of heterogeneous wireless networks over a common IP infrastructure enable ubiquitous access to network services in next generation wireless networks (NGN). This wireless access network heterogeneity combined with the availability of multi-interface mobile devices creates an environment where handovers between different access technologies is inevitable. Therefore, operators with multiple networks will need to facilitate seamless network access across their multiple systems. However, mobility management protocols do not provide seamless handover in their current form. Thus, we propose to introduce a handover coordinator in heterogeneous wireless network environment supported by Proxy Mobile IPv6 to enhance seamless and soft handover that will reduce handover delay and packet loss during the handover period. Simulation results show that the proposed network-based handover mechanism reduces handover delay and number of dropped packets though at the sacrifice of a slight signaling overhead.
