A Novel Handover Mechanism of PMIPv6 for the Support of Multi-Homing Based on Virtual Interface

The Proxy Mobile IPv6 (PMIPv6) is a network-based accessibility managing protocol. Because of PMIPv6’s network-based approach, it accumulates the following additional benefits, such as discovery, efficiency. Nonetheless, PMIPv6 has inadequate sustenance for multi-homing mechanisms, since every mobility session must be handled through a different binding cache entry (BCE) at a local mobility anchor (LMA) according to the PMIPv6 specification, and thus PMIPv6 merely permits concurrent admittance for the mobile node (MN) which is present in the multi-homing concept. Consequently, when a multi-homed MN interface is detached from its admittance network, the LMA removes its moving part from the BCE, and the current flows connected with the apart interface are not transmitted to the multi-homed MN, even if a more multi-homed MN interface is still linked to another access network. A superior multi-homing support proposal is proposed to afford flawless mobility among the interfaces for a multi-homed MN to address this problem. The projected method can shift an application from a disconnected interface of a multi-home MN to an attached interface using the PMIPv6 fields of Auxiliary Advertisement of Neighbor Detection (AAND).

Encountering Chinese development in the Maldives

This chapter examines the longest and most developed road in the Maldives archipelago, a fifteen-kilometre-long link road connecting four islands of the Laamu (or Haddummati) Atoll. In the planning phase, there were tensions between those who argued that the road should connect houses to the school and the mosque and those who argued that the road should connect the harbour to the market. Such appeals, bifurcated along gender lines, reflect local mobility concerns and were tied to existing political rifts between the four islands that were intensified by the appearance of a new infrastructural asset. The built road facilitates a multitude of local encounters as people travel further and more regularly, but it is also through the road that islanders encounter the global forces of capital and construction that shape their islands. The Laamu link road was a ‘gift’ from the Chinese government, constructed by the Jiangsu Transportation Engineering Group (JTEG), and amidst local mobility concerns and inter-island politics swirl rumours and hearsay of land grabs and international power struggles between China, India, the US, and Saudi Arabia. This chapter, as well as being an ethnographic exposition of Chinese infrastructure development in a South Asian archipelago, explores the road as a social experience as it crosscuts competing visions of modernity, global connectivity, and anxiety about material change on remote coral atolls in the Indian Ocean.

COVID-19: Examining the case growth-rate due to Visitor vs Local Mobility using Machine Learning: A Study in the United States

Background: Travel patterns of humans play a major part in the spread of infectious diseases. This was evident in the geographical spread of COVID-19 in the United States. However, the impact of this mobility and the transmission of the virus due to local travel, compared to the population traveling across state boundaries, is unknown. This study evaluates the impact of local vs. visitor mobility in understanding the growth in the number of cases for infectious disease outbreaks. Methods: We use two different mobility metrics, namely the local risk and visitor risk extracted from trip data generated from anonymized mobile phone data across all 50 states in the United States. We analyzed the impact of just using local trips on infection spread and infection risk potential generated from visitors' trips from various other states. We used the Diebold-Mariano test to compare across three machine learning models. Finally, we compared the performance of models, including visitor mobility for all the three waves in the United States and across all 50 states. Results: We observe that visitor mobility impacts case growth and that including visitor mobility in forecasting the number of COVID-19 cases improves prediction accuracy by 34. We found the statistical significance with respect to the performance improvement resulting from including visitor mobility using the Diebold-Mariano test. We also observe that the significance was much higher during the first peak March to June 2020. Conclusion: With presence of cases everywhere (i.e. local and visitor), visitor mobility (even within the country) is shown to have significant impact on growth in number of cases. While it is not possible to account for other factors such as the impact of interventions, and differences in local mobility and visitor mobility, we find that these observations can be used to plan for both reopening and limiting visitors from regions where there are high number of cases.

Role of COVID-19 and motionless communication on expected trends of mobility: an evidence from Italian and Turin data

The 2020 pandemic has been changing for months the everyday mobility of part of the world: we concentrate on one of the first areas hit by COVID-19, soon after China. One of the main elements of change is the consolidation of teleworking, which further prompted motionless communications. The emergency-induced reduction of the systematic travel demand has been counterbalanced by the increased volume of web traffic. As a result, communications which formerly required commuting or travel missions have been regularly performed motionless during the lockdown. All this is known, also by experience. The novelty is that this paper quantifies this phenomenon, with a focus on the city of Turin, Italy, and makes hypotheses on the post-COVID. Local mobility data, so as trends before and during the lockdown are presented, thereafter compared. Implications for the “new normal” ahead are fully elaborated, to reply to a pre-existing research question on the role of motionless communications in the future urban mobility management. Eventually, the paper provides directions to advance and create a reference for further transport policies, within the general research goal to contribute to advance scientific knowledge in this new transportation study topic.

Design and Performance Analysis for Edge Intelligence-Based F-PMIPv6 Mobility Support for Smart Manufacturing

In this paper, we propose a new mobility management network, i-FP, to be used in the smart factory that continues to develop in the Fourth Industrial Revolution. i-FP was created to solve the current local mobility management problem of legacy frameworks. MN (mobile node) refers to a mobile device in a manufacturing environment that includes workers, production facilities, and AGV. To allow mobile nodes (MNs) to move from one domain to another, i-FP uses three network entities: LFA (Local Factory Anchor), FAG (Factory Access Gateway), and MN, as an extended concept of PMIPv6. Among the three network entities in i-FP, LFA and FAG can act as edge intelligence devices to reduce the handover latency of the MNs. i-FP also uses IP header-swapping mechanisms to prevent traffic overhead and enhance network throughput. We evaluate new framework i-FP, PMIPv6, and HMIPv6, which are legacy protocols of local mobility management, in various ways and evaluate three schemes. We confirm that i-FP works better than do the other network methods used in the smart factory.
