The impact of extreme events across the globe is extraordinary which continues to handicap the advancement of the struggling developing societies and threatens most of the industrialized countries in the globe. Various fields of Information and Communication Technology have widely been used for efficient disaster management;but only to a limited extent though, there is a tremendous potential for increasing efficiency and effectiveness in coping with disasters with the utilization of emerging wireless network technologies. Early warning, response to the particular situation and proper recovery are among the main focuses of an efficient disaster management system today. Considering these aspects, in this paper we propose a framework for developing an efficient Disaster Management Communications and Information System (DMCIS) which is basically benefited by the exploitation of the emerging wireless network technologies combined with other networking and data processing technologies.

Mobile Device Cloud (MDC) has become a promising collaborative cloud computing environment that exploits idle resources on nearby mobile devices to execute compute-intensive applications. In the existing MDC system, user tasks are executed by the worker devices either voluntarily or with an amount that leads to overpayment resulting dissatisfaction for both user and worker devices. Therefore, a major challenge is to minimize the execution cost of user codes while supporting sufficient payments to the workers for their used resources. Furthermore, selection of reputed workers becomes more complicated when the workers are having heterogeneous resources. In this paper, we formulate a greedy algorithm to minimize the task execution cost with reputed worker devices, while maintaining the desired quality of execution. The simulation results exhibit that our proposed algorithm can minimize the task execution cost up to 30 % compared to a state-of-the-art work. © 2019 IEEE.

Collecting data from heterogeneous on body and implanted sensor devices of Wireless Body Area Network (WBAN) is a challenging problem due to interference and strict delay deadlines of application data. While prioritized data collection is addressed in the literature for inter-WBANs, however how to prioritize medium accesses from different intra-Wban sensor devices is yet to be explored. In this work, we develop collaborative medium access mechanisms (CMAC) for critical and noncritical data traffic co-located with relevant data. We develop new super frame structures for accommodating different data types and schedule their transmissions based on their priorities. The result of performance analysis depicts that the proposed MAC mechanism offers significantly reduced data delivery delay for the critical traffic compare to its counterpart. © 2019 IEEE.

IEEE Transactions on Parallel and Distributed Systems 2009年第1期20卷 48-58页

作者： Kuo, Chin-Fu Pang, Ai-Chun Chan, Sheng-Kun Department of Computer Science and Information Engineering National University of Kaohsiung Taipei 106 Taiwan Graduate Institute of Networking and Multimedia Department of Computer Science and Information Engineering National Taiwan University Taipei 106 Taiwan Co. Ltd. Taiwan

Security has become one of the major issues for data communication over wired and wireless networks. Different from the past work on the designs of cryptography algorithms and system infrastructures, we aim at the proposing of a dynamic routing algorithm that could randomize delivery paths for data transmission. The algorithm is easy to implement and compatible with popular routing protocols, such as Routing Information Protocol in wired networks and Destination-Sequenced Distance Vector protocol in wireless networks, without introducing extra control messages. An analytic study on the proposed algorithm is presented, and a series of simulation experiments are conducted to verify the analytic results and to show the capability of the proposed algorithm. © 2009 IEEE.

Creating infrastructures, virtual servers, computing resources, along with devices is termed virtualisation. In this methodology, to augment resource usage along with to mitigate the total power consumption, mapping of a group of virtual machine (VM) onto a set of physical machines (PM) is performed in a data centre (DC). Nevertheless, a crucial challenge is presented by the VM allocation together with the higher energy consumption (EC) of cloud data centres (CDC). Thus, to alleviate the resource wastage along with to mitigate the DCs' EC, an effectual Fisher Yates-Shuffled frog leaping algorithm (FY-SFLA) is proposed here: 1) task feature extraction;2) resource information extraction;3) task separation by utilising cosine distance - K means algorithm (CD-KMA);4) task placement in VM by employing the FY-SFLA task;5) VM status identification by deploying random mutation monkey search deep learning vector quantisation (RMMS - DLVQ) are '5' phases comprised in the proposed methodology. © 2023 Inderscience Enterprises Ltd.

With increasing demand on bandwidth and mobile media applications, pressures upon network providers to provide more bandwidth to users and better Quality of Service (QoS) is increasing. For example, High Definition (HD) Video on Demand (VoD) streaming requires an average of 10 Mb/sec per user. Meeting these needs through the use of fiber optic networks to backhaul the traffic is essential, since fiber optic networks provide bandwidth measured at a rate of Gb/sec. However, most mobility management protocols are not built to handle fiber optic networks. Ethernet Passive Optical Network (EPON) is the dominant fiber optic network in the market due to its simplicity and cost of deployment. This paper describes how EPON can be used effectively to meet the need for increased bandwidth and handoff demands of mobile terminals. This paper studies Proxy Mobile IPv6 (PMIPv6) as the dominant network-based localized mobility management (Netlmm) protocol. Vehicle Ad Hoc Network (VANET) amplifies the handoff problems due to its unique characteristics. Hence, the issues and challenges of using the EPON network with PMIPv6 will be analyzed. Finally, recommendations will be established to optimize the usage of EPON with local mobility management protocols. This research shows by means of analysis the need for new protocols to support fast mobile IP optimization and then propose a solution that is tailored for EPON and analyze the proposed solution mathematically. © 2013 ACM.

Most data aggregation and dissemination approaches for VANETs attempt to create and utilize a structure for collecting information. The structures vary and could be categorized as either node-centric, as in a tree, mesh, or a cluster, or road-centric as in highway segmentation. In this paper we present a structureless information dissemination scheme that creates a layered view of road conditions with a diminishing resolution as the geocast distance increases. Our scheme first provides a high-detail local view of a given vehicle's neighbors and their immediate neighbors, which is further extended when information dissemination is employed. The scheme also allows for the preservation of unique reports within aggregated frames, such that safety-critical notifications are kept in high detail, all for the benefit of the driver's improved decision making during emergency scenarios. Here we report that our scheme provides the driver with a high detail view of road conditions sufficiently far ahead, as well as with aggregated information for the length of the whole geocast distance, all while preserving safety critical reports. © 2010 IEEE.

Rainfall is the greatest of nature's gifts for our daily life, as well as the most important climate factor affecting human lives with farmers and agricultural complex systems. Rainfall forecasting is very difficult because excessive and sudden rainfall can have numerous problems, such as agriculture and property destruction, so for a better forecasting model is required for early warning that can save risk to agriculture and life property. Time series data have been used extensively in classical statistics. The proposed methodology predicts annual rainfall by time series ARIMA model and Linear Regression a machine learning algorithm. Time series data have been used extensively in classical statistics. The ARIMA has been trained to produce excellent outcomes. The ARIMA model demonstrated greater accuracy in all seasonal and yearly rains. To offer a solid prediction, this method, like time series ARIMA, requires a strict assumption of stationarity. We use real data from the Indian government website and Kaggle to compare model quality in ARIMA using different evaluation metrics. As a result, the ARIMA model accurately predicts rainfall and it is used for agriculture purpose in future. © 2022 IEEE.
