Transport analytics in action: a cloud-based decision support system for efficient city bus transportation

Optimising city bus transport operations helps conserve fuel by providing the urban transport service as efficiently as possible. This study develops a Cloud-based Decision Support System (C-DSS) for transport analytics. The C-DSS is based on an intelligent model on location of depots for opening new depots and/or closing a few existing depots and allocation of city-buses to depots. The C-DSS is built on the Cloud Computing architecture with three layers and includes an efficient and simple greedy heuristic algorithm. Using modern information and communications technology tools, the proposed C-DSS minimizes the cost of city bus transport operations and in turn to reduce fuel consumption and CO2 emissions in urban passenger transport. The proposed C-DSS is demonstrated for its workability and evaluated for its performance on 25 large scale pseudo data generated based on the observation from Bangalore Metropolitan Transport Corporation (BMTC) in India

An Autonomic Algorithm For Data Dissemination In Vehicular Ad Hoc Networks

A Vehicular Ad Hoc Network (VANET) is a subclass of Mobile Ad Hoc Networks, which provides wireless communication among vehicles as well as between vehicles and roadside units. Providing safety, traffic efficiency and user comfort for drivers and passengers are promising goals of these networks. Due to some inherent characteristics of VANETs, such as intermittent connectivity, highly dynamic topology, and diverse network densities, data dissemination is a challenging activity in this kind of network. Although data dissemination has been extensively studied in the literature, existing solutions do not effectively address the broadcast storm and network partition problems when considered together. To deal with both problems, we propose a network partition-aware geographical data dissemination protocol, which eliminates the broadcast storm and maximizes the data dissemination capability across network partitions with short delays and low overhead. The proposed algorithm is able to autonomically adjust message transmissions in the network. Simulation results show that our proposed approach provides good efficiency with respect to the coverage of event processing, delay and overhead.123430435Williams, B., Camp, T., Comparison of broadcasting techniques for móbile ad hoc network Proceeding of the 3rd ACM Internacional Symposium on Mobile Ad Hoc Network &ampComputing, , MobiHoc 02, páginas 194-205, New York, NY, EstadosUnidosSpyropoulos, T., Psounis, K., Raghvendra, C.S., Efficient routing in intermittently connected móbile network: The multiple-copy case IEEE/ACM Trans.

User-centric Mobility Management Architecture For Vehicular Networks

Vehicular Ad Hoc Network (VANET) is a subclass of Mobile Ad Hoc Networks that provides wireless communication among vehicles as well as between vehicles and roadside devices. Providing safety and user comfort for drivers and passengers is a promising goal of these networks. Some user applications need a connection to internet through gateways which are in the road side. This connection could generate an overhead of control messages and also the handover time among gateways can affect the performance of these applications. This paper proposes an architecture for intra- and inter-system management for virtual environments in vehicular networks, supporting user-driven applications. More specifically, we consider applications that depend on virtual environments which must be constantly updated, such as online gaming. To efficiently support these applications, the proposed architecture includes an extension of the 802.21 protocol to cope with the virtual environment updates. NS3 simulations were performed to evaluate the proposal over the proxy MIPv6 considering VANET and LTE networks as base stations. We observed that the proposed mechanism that extends the 802.21 protocol had a shorter handover time and lower packet loss when acting with the presented architecture.584256Technische Universitat Hamburg-Harburg,IEEE Communications Society Germany ChapterKaragiannis, G., Altintas, O., Ekici, E., Heijenk, G., Jarupan, B., Lin, K., Weil, T., Vehicular networking: A survey and tutorial on requirements, architectures, challenges, standards and solutions (2011) IEEE Communications Surveys Tutorials, 13 (4), pp. 584-616Asgari, M., Jumari, K., Ismail, M., (2011) Analysis of Routing Protocols In Vehicular Ad Hoc Network Applications, 181, pp. 384-397. , In: Zain, J.M., Wan Mohd, W.M.B., El-Qawasmeh, E.

Vanets: An Exploratory Evaluation In Vehicular Ad Hoc Network For Urban Environment

Vehicular Ad hoc Network (VANET) is a promising communication technology suitable for vehicular mobile networks. Represent networks of singular features, wherein the data dissemination is fundamental. The literature is plentiful in protocols, usually specific to address individual issues in well-defined scenarios. This work efforts are concentrated, mainly, to examine operating settings in protocols like AID, DBRS, and ADDHV for disseminating messages. A benchmarking explores strategies that address challenges such as network partitioning and the broadcast storm problem, which undertake the dissemination. The results of a set of metrics obtained in different vehicular traffic schemes complete the discussion held. Considerations for answers in coverage, delay, rate of delivery, broadcast, and packet loss support this initiative and motivate the development of an adaptive solution to fluctuations in carrier density.4549Akamai Technologies, Inc.,IEEE Computer Society Technical Committee on Distributed Processing (TCDP),IEEE Computers Society,International Research Institute on Autonomic Network Computing,Technical Committee on Distributed ProcessingMoustafa, H., Zhang, Y., (2009) Vehicular Networks: Techniques, Standards, and Applications, , 1st ed.

A novel fog-based resource allocation policy for vehicular clouds in the highway environment

Vehicular networks has unique characteristics compared to other wireless networks, such as, highly dynamic topology, short transmission time, among others. These characteristics becomes a challenge for management and allocation of vehicle cloud resources. In this paper, we propose a allocatioN and mANgement resourCe policY for vehicular cloud, called of NANCY. For this, we formulate the problem of allocation of resources through the mathematical method Multiple Attribute Decision, which will decide whether NANCY will allocate the resources available to attend or not the service requested by the vehicle. Simulation results showed that NANCY provides a larger amount of service to be provided, providing a reduction in the number of service locks due to its accuracy, as well as a reduction in the amount of services discarded due to its load balancing in resource allocation.IEEE Latin-American Conference on Communication
