Abstract
Mobile data traffic has increased significantly due to the evolution of wireless communication technologies. The Information Centric Network paradigm is considered as an alternative to bypass the restrictions imposed by the traditional IP networks, especially those related with the mobility of its users. Despite the potential advantages of this paradigm regarding mobile wireless environments, several research challenges remain unaddressed, more specifically the ones related with the communication damage caused by handovers. This work presents a Named Data Network (NDN) based solution that supports Consumer mobility. The proposed scheme addresses a mobility manager entity that monitors and anticipates trajectories, while compelling the infrastructure to adjust to the new paths. This process results in an efficient way to manage the Consumers’ mobility, and therefore, in a better quality of service to its users. The implementation and evaluation of the proposed solution uses the ndnSIM, through functional and non-functional scenarios, and with real traces of urban vehicular mobility and connectivity. The results show that the proposed solution is superior to the native NDN workflow with respect to content delivery ratio and number of timeouts.
Highlights
Over the last years we have witnessed a significant increase in the number of portable communication devices, and its dominance over the Internet traffic
Such challenges and demands are expected to increase with the advent of Internet of Things (IoT) and 5G/6G, where billions of IoT devices, many of them mobile, are expected to be connected in the near future, supporting many future applications, such as the ones that make up a Smart City [1]
Being presented as a promising alternative to the current Transmission Control Protocol (TCP)/IP Internet architecture, the truth is that Named Data Network (NDN) still presents a large number of research challenges, including for example the lack of support regarding the mobility of its network elements, especially Consumers [4]
Summary
Over the last years we have witnessed a significant increase in the number of portable communication devices, and its dominance over the Internet traffic. Location-oriented networks are frequently dependent on connection-oriented protocols, for example, the Transmission Control Protocol (TCP) This means that, to settle the communication between two entities, a session between a client and a server needs to be established. Being presented as a promising alternative to the current TCP/IP Internet architecture, the truth is that NDN still presents a large number of research challenges, including for example the lack of support regarding the mobility of its network elements, especially Consumers [4]. The proposed scheme adapts and extends concepts from ICNs, through the dissemination and caching of the content at new recipients to serve a mobile Consumer This requires the inquiry for the new location, which will be calculated by a remote mobility manager entity, resulting in a better quality of content delivery to Consumers
