A wireless node might probably get assigned a new IP address when switching connectivity between different service providers through handover. For a running session with specific quality of service requirements, IP address resolution upon handover is a crucial factor that has impact on session continuity. This work focuses on handover from the addressing prospect without discussing the phases of handover...
In next generation networks (5G for example), seamless-soft handover is to be highly supported between wireless networks regardless of the underlying radio access technology. Each network differs and might be evaluated in terms of multiple attributes like coverage area, available bandwidth, cost, etc. In such environments, users might want to apply some preferences in the selection process to promote...
The coexistence and overlap of the different wireless networks available nowadays can be beneficial for mobile nodes. Whenever a better network/service provider is available, handover may be preferred. Wireless networks might differ in characteristics like IP network address, radio access type, supported services, coverage area, bit rate and cost. Users might like to apply certain preferences to handover...
During disaster relief missions, it is essential to provide reliable communication between the different rescue teams and to the victims as well. Since a disaster is likely toe Mobile Ad hoc Networks (MANETs) are the best choice to reestablish communication. However, this type of networks has a major drawback, it can only cover relatively small areas. In large disaster sites, this results in creating...
Vehicular communications have become very important in the recent years. Vehicles instantaneously form networks and utilize the available communication infrastructure. The vehicles' mobility is one of the major challenges in vehicular communications. In car-to-infrastructure communications, a vehicle is assigned an IP address through the network it is connected to, and thus mobility means a new IP...
Intermittent connectivity is one major challenge for mobile nodes that move between different networks. Existing handover procedures are able to maintain the connectivity, if the communication ranges of the networks overlap. Otherwise, the connection will be lost. This is especially problematic for e-health applications, when emergency physicians are on the way to a patient and need to stay in contact...
