Cellular networks have gained a lot of popularity in the context of vehicular communication within the last few years. Existing reference architectures such as CALM already consider them to provide enhanced connectivity to vehicles for data communication. Their capabilities, especially 3G and next-generation, translate into great potential in the vehicular environment, far beyond the provision of...
This paper presents VANBA, a simple, ready-to-use mechanism to perform vertical handovers in vehicular networks that integrates the essential functionalities of the Always Best Connected (ABC) paradigm in a transparent way both to the user and the upper-layer applications even in terminals with limited processing capabilities. This mechanism operates at the network layer and achieves quasi-continuous...
