In this paper the multiple challenges for handovers in hybrid networks are discussed. Based on that a location-based handover for hybrid networks is evaluated. The handover takes into consideration the increased handover preparation time in hybrid networks, coming from the use of different air interfaces and the interoperation of different network providers. Also the security of the connection ...

Dual-mode handsets and multimode terminals are generating demand for solutions that enable convergence and seamless handover across heterogeneous access networks. The IEEE 802.21 working group is creating a framework that defines a Media Independent Handover Function (MIHF), facilitates the handover across heterogeneous access networks and help mobile users to experience a better performance du...

In recent years, the integration of Worldwide Interoperability for Microwave Access (WiMAX) and Ethernet Passive Optical Network (EPON) has become one of the most promising broadband access solutions. The EPON network provides tremendous bandwidth while the WiMAX network can support mobility. Integration of PON and WiMAX combines the best of both technologies. However, the integration requires ...

Quality of Service (QoS) mechanisms in networks supporting mobile Internet communications give rise to Denial of Service (DoS) threats: if the network cannot efficiently check the credibility of a QoS request during a handover process, malicious entities could flood the network with bogus QoS requests; if the authentication check is performed by means of an AAA protocol before the access networ...

With the increasing number of mobile and wireless networks that are deployed, the handovers between these systems take place more often. In order to provide end-users with uninterrupted access to services, support for fast handover is essential. One of the prerequisites of a fast-handover is transparent end-user authentication. In this paper we address end-user authentication at network level. ...

Mobility management is the key feature of wireless network. When the mobile node roams from the home network to the foreign network, the foreign network access server usually does not have the security material of the mobile node, and can not authenticate the mobile node by itself. Thus the three-party authentication is used, and the foreign network access server consults the home authenticatio...

We investigate the possible application of Mobile Intelligent Agent for early authentication prior to the handove. Seamless handover is required in VoIP mobility services in order to limit the period of the service disruption experienced by a MN when moving between different IP subnets. Our seamless handover method involves early deployment of multiple copies of the Mobile Intelligent Agents to...
