Adaptive Resource Allocation in Mobile Ad Hoc Computational Grids

Sayed Chhattan Shah,Wan Sik Choi 제어로봇시스템학회 2012 제어로봇시스템학회 국제학술대회 논문집 Vol.2012 No.10

Two key components contribute to task completion time: execution cost and communication cost. The communication cost is induced by data transfers from one task to another residing on separate nodes. To reduce communication cost, interdependent tasks are allocated to closely located nodes. However, once tasks are allocated, nodes can move within a Grid. The node mobility within a Grid can increase communication distance and may result into multi-hop communication between nodes executing dependent tasks. The multi-hop communication increases communication cost and thus task completion time. In order to avoid multi-hop communication between dependent tasks, we have developed an adaptive and distance-based resource allocation scheme which exploits the characteristics of an application and nodes, and applies migration heuristics to reduce communication cost. The scheme is validated in a simulated environment using various workloads and parameters.

Muhammad Bilal Khan,강문수,Shah Sayed Chhattan,강신각 한국전자통신연구원 2014 ETRI Journal Vol.36 No.3

To achieve high-speed (giga-bit) connectivity for shortrangewireless multimedia applications, the millimeterwave(mmWave) wireless personal area networks withdirectional antennas are gaining increased interest. Due tothe use of directional antennas and mmWavecommunications, the probability of non-interferingtransmissions increases in a localized region. Networkthroughput can be increased immensely by the concurrenttime allocation of non-interfering transmissions. Theproblem of finding optimum time allocation for concurrenttransmissions is an NP-hard problem. In this paper, wepropose two enhanced versions of previously proposedmulti-hop concurrent transmission (MHCT) schemes. Toincrease network capacity, the proposed schemes efficientlymake use of the free holes in the time-allocation map of theMHCT scheme; thus, making it more compact.

<P><B>Abstract</B></P> <P>The Internet of Things (IoT) provides a global communication network between millions of devices connected to the internet. Similarly, the emergence of heterogeneous wireless networks provides a medium to the IoT communication paradigm. In order to enable an energy-friendly communication in an IoT environment, such as smart home, office, city, etc. we propose an energy-aware communication systems for IoT environments. The proposed scheme works in several phases such as identification of high energy require appliances, deployment of sensors, scheduling, etc. Moreover, the data from the IoT devices are collected through sensors. The data is tested using the Hadoop ecosystem for future planning and efficient usage of the energy in an IoT environment. The proposed architecture is tested in a different scenario against the Wireless Sensor Network (WSN) based IoT architecture in the context of energy consumption. The proposed architecture performs efficiently than WSN in a number of scenarios. Similarly, the efficiency and processing time of the Hadoop system is computed which shows better results.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Internet of Things (IoT) provides a global communication network between millions of devices. </LI> <LI> Energy-aware communication systems for IoT environments. </LI> <LI> Scheduling mechanisms are used to prioritize the home appliances. </LI> </UL> </P>

EBCO - Efficient Boundary Detection and Tracking Continuous Objects in WSNs

( Sajjad Hussain Chauhdary ),( Jeongjoon Lee ),( Sayed Chhattan Shah ),( Myong-soon Park ) 한국인터넷정보학회 2012 KSII Transactions on Internet and Information Syst Vol.6 No.11

Recent research in MEMS (Micro-Electro-Mechanical Systems) and wireless communication has enabled tracking of continuous objects, including fires, nuclear explosions and bio-chemical material diffusions. This paper proposes an energy-efficient scheme that detects and tracks different dynamic shapes of a continuous object (i.e., the inner and outer boundaries of a continuous object). EBCO (Efficient Boundary detection and tracking of Continuous Objects in WSNs) exploits the sensing capabilities of sensor nodes by automatically adjusting the sensing range to be either a boundary sensor node or not, instead of communicating to its neighboring sensor nodes because radio communication consumes more energy than adjusting the sensing range. The proposed scheme not only increases the tracking accuracy by choosing the bordering boundary sensor nodes on the phenomenon edge, but it also minimizes the power consumption by having little communication among sensor nodes. The simulation result shows that our proposed scheme minimizes the energy consumption and achieves more precise tracking results than existing approaches.

<P>Chikungunya is a mosquito instinctive disease that spreads hurriedly in various parts of the country. For the awareness and prevention measure of this disease a new paradigm in Smart Health (S-Health) required to be devised. The auspicious prospective of evolving Internet of Things (IoT) technologies for interconnected heterogeneous devices and objects has played a vital role in the next generation health care systems for eminent patient care to protect the citizens from these types of diseases. Still there is a need for real time health monitoring to analyze the patients for early preventive measures and precautions for healthy life. S-Health care IoT has substantial impending for the cognizance of analogues monitoring. It includes the interconnected apps, objects (devices and people), communication technologies, tracking system, and patients’ knowledge base. This paper presents an IoT-enabled model where data collected from the sensors, objects, and people will be gathered at the cloud to take the preventive actions by healthcare professionals. Precautionary measures will be taken by collecting the information about causes of growth of mosquitoes. The suitability of the approach is validated at the base layer of the IoT and data is transmitted to the cloud with the help of edge nodes.

Social Internet of Vehicles: Architecture and enabling technologies

Butt, Talal Ashraf,Iqbal, Razi,Shah, Sayed Chhattan,Umar, Tariq Elsevier 2018 Computers & electrical engineering Vol.69 No.-

<P>The key goal of Internet of Things (IoT) has been the provision of value-added services based on the ubiquitously available smart devices that can offer diverse services by interacting with each other. However, the paradigm has evolved to its next phase, Social Internet of Things (SIoT), with the inception of an idea to empower these devices with consciousness. This cognizance enables these smart devices to socialize with each other based on shared context and mutual interests. The Social Internet of Vehicles (SIoV) applies SIoT concepts in the vehicular domain to revolutionize the existing ITS (Intelligent Transport System) by adding value to existing VANET (Vehicular Ad-hoc Network) technology. This paper presents a scalable SIoV architecture based on Restful web technology. Furthermore, this paper emphasizes the importance of web technology to meet the required interoperability to support the composition of numerous services. The paper also discusses the enabling technologies and protocols.</P>

Khelifi, Hakima,Luo, Senlin,Nour, Boubakr,Shah, Sayed Chhattan Hindawi Limited 2018 Mobile information systems Vol.2018 No.-

<P>A tremendous amount of content and information are exchanging in a vehicular environment between vehicles, roadside units, and the Internet. This information aims to improve the driving experience and human safety. Due to the VANET’s properties and application characteristics, the security becomes an essential aspect and a more challenging task. On the contrary, named data networking has been proposed as a future Internet architecture that may improve the network performance, enhance content access and dissemination, and decrease the communication delay. NDN uses a clean design based on content names and Interest-Data exchange model. In this paper, we focus on the vehicular named data networking environment, targeting the security attacks and privacy issues. We present a state of the art of existing VANET attacks and how NDN can deal with them. We classified these attacks based on the NDN perspective. Furthermore, we define various challenges and issues faced by NDN-based VANET and highlight future research directions that should be addressed by the research community.</P>
