The next generation (NG) wireless system called Beyond 3G is envisioned as seamless worldwide wireless systems. Handover latency is an important metric for NG wireless system. This paper analyzes the handover latency of mobility support schemes including Mobile Ethernet. We compare various mobility support schemes from multiple viewpoints. For the quantitative evaluation, we introduce an analytical network model through a Markovian model. The sequence of location update frames in four schemes, i.e., Mobile Ethernet, a scheme of using MPLS, a scheme of using VLAN tag, and Mobile IPv6, formulates the handover latency and handover costs. The combination of the latency of each switch, router, and link defines handover latency. The feature of this analysis evaluates the latency of four schemes within the same model. Numerical result shows Mobile Ethernet achieves small handover latency. By means of analytical results about handover latency and handover costs, we consider the benefit of each scheme.

Heterogeneous wireless access is being integrated into IP networks to support future wireless systems. The enhanced IP technologies being developed must address both handover issues related to mobility management and security issues related to wireless access. We previously proposed a network architecture, Mobile Ethernet, based on wide area Ethernet technologies, that reduces overhead involving handover by managing mobility in the IEEE802 MAC layer. We also proposed a virtual MAC address scheme that introduces a host identifier into layer 2 to accommodate heterogeneous wireless access, manage handover between wireless accesses, provide scalability, and ensure security. In this paper, we design the virtual MAC address scheme for Mobile Ethernet and describe the sequence diagrams of the scheme. We also clarify the effect of our proposed scheme from the viewpoint of scalability by comparing the simulated signaling traffic load at handover with that using FMIPv6.

“…INTRODUCTION Success of next generation cellular communications depends on the introduction of new and exciting services such as full scale high speed internet support and content-rich multimedia delivery alongside the existing voice centric services [1]. Provision of quality of service (QoS) support for these services are crucial for reliable transmission of content over wireless links which are susceptible to time varying impediments including noise and interference due to the mobility of users [2].…”

Assuring quality of service (QoS) is an extreme challenge in cellular multimedia delivery. Without appropriate QoS, the content delivered cannot meet consumers' aesthetic demands and thus resulting in revenue loss for the service provider. In this paper, we propose a novel multi-path cellular network architecture through placement of additional base stations (BSs), i.e., antennae in the existing cellular architecture. This architecture provides a MU more than one communication links with the BSs placed in different locations. The availability of multiple channels allows the implementation of path diversity transmission protocols and improves error resilience capability for multimedia services. The problem of link failure and blind spots in the existing cellular networks are handled for voice communications as at least one base station can maintain a line of sight communication path with the MU. The distributed nature of base station placement and multiple diversified path links also reduces outage probability. We show that our proposed architecture provides better reliability and maintains cell capacity for high bandwidth multimedia services while improving signal to interference ratio compared to the existing cellular network model.Keywords-cellular network architecture, multi-path communication, quality of service assurance, multimedia content delivery, cellular internet facility.
