Efficient Coordinated Power Distribution on Private Infrastructure

Current power distribution network design makes it attractive for agents to generate their own power (distributed generation) and to construct private infrastructure (e.g., distribution lines) to exchange power without using the main public grid. We show that such private transactions may increase overall network load because of increased transmission distances, thus increasing resistive losses. We present a coordination scheme for the centralized control of private infrastructure that satisfies participation constraints and budget balance. Experiments show that our scheme reduces distribution losses by 4-5 % when there are only a constant number of private lines and by 55%-60 % when the number of private lines is proportional to the number of agents

Game-theoretic Resource Allocation Methods for Device-to-Device (D2D) Communication

Device-to-device (D2D) communication underlaying cellular networks allows mobile devices such as smartphones and tablets to use the licensed spectrum allocated to cellular services for direct peer-to-peer transmission. D2D communication can use either one-hop transmission (i.e., in D2D direct communication) or multi-hop cluster-based transmission (i.e., in D2D local area networks). The D2D devices can compete or cooperate with each other to reuse the radio resources in D2D networks. Therefore, resource allocation and access for D2D communication can be treated as games. The theories behind these games provide a variety of mathematical tools to effectively model and analyze the individual or group behaviors of D2D users. In addition, game models can provide distributed solutions to the resource allocation problems for D2D communication. The aim of this article is to demonstrate the applications of game-theoretic models to study the radio resource allocation issues in D2D communication. The article also outlines several key open research directions.Comment: Accepted. IEEE Wireless Comms Mag. 201

Cloud Computing for Supply Chain Management and Warehouse Automation: A Case Study of Azure Cloud

In recent times, organizations are examining the art training situation to improve the operation efficiency and the cost of warehouse retail distribution and supply chain management. Microsoft Azure emerges as an expressive technology that leads optimization by giving infrastructure, software, and platform resolutions for the whole warehouse retail distribution and supply chain management. Using Microsoft Azure as a cloud computing tool in retail warehouse distribution and supply manacle management contributes to active and monetary benefits. At the same time, potential limitations and risks should be considered by the retail warehouse distribution and the supply chain administration investors. In this research summary of the cloud figuring tool, both public and hybrid in supply chain administration and retail, warehouse distribution is addressed. A brief introduction to the use of Microsoft Azure technology is provided. This is followed by the application of cloud computing to warehouse retail distribution and supply chain management activities. At the same time, the negative and positive aspects of familiarizing this Microsoft Azure technology in the modern supply chain and retail distribution are debated. Also, the circumstance for the third-party logistics services suppliers has indicated respect for automation and cybersecurity solutions in a cloud environment. Lastly, the upcoming research practices and following technological trends are offered as the conclusion

Vehicle to Vehicle Communication System for Smart Cities

A Vehicle-to-Vehicle (V2V) communication system for smart cities is proposed here. The V2V communication system is an advance wireless technology to reduce the number of fatal roadway accidents by providing early warning messages. For development of smart cities V2V and V2R are important to reduce road accidents on highways. It gives ease of access by providing different facilities such as ATM transaction, accidents safety messages to the transport or central unit. Based on a careful analysis of application requirements, an effective protocol can be used, which comprising congestion control policies, service differentiation mechanisms and methods for emergency warning dissemination. The proposed protocol achieves low latency in delivering emergency warnings and use of efficient bandwidth in stressful road scenarios. This system uses WSN for communication between two vehicle modules

Collaboration Circles: empowering job seekers to find work using ad-hoc collaboration networks

Recent trends combine smart phones with social networking platforms to bring new opportunities that can enable people to collaborate anywhere and at any time. For example, organisations can be given the opportunity to recruit part-time job seekers such as software developers using social media tools. Previously, collaboration was static in nature, but today loosely enabled collaboration needs to support flexible schedules, ad hoc processes and members that may not be known in advance. Furthermore, current crowdsourcing platforms that enable software developers to contribute their skills to projects do not meet the social needs of participants as they collaborate. This paper presents a cost-effective approach to collaboration that aims to assist users to find suitable collaborators to team up with. The proposed Collaboration Circles application is able to find the best time to collaborate using Google+, Google calendar and a weighted assignment algorithm. The Collaboration Circles application includes features such as the administration of collaborative task activities and communication channels. The Collaboration Circles application is implemented as an Android social network application supported by Google tools. The application is experimentally evaluated to demonstrate that the Collaboration Circles application successfully supports collaboration in the virtual world

The Case for Liberal Spectrum Licenses: A Technical and Economic Perspective

The traditional system of radio spectrum allocation has inefficiently restricted wireless services. Alternatively, liberal licenses ceding de facto spectrum ownership rights yield incentives for operators to maximize airwave value. These authorizations have been widely used for mobile services in the U.S. and internationally, leading to the development of highly productive services and waves of innovation in technology, applications and business models. Serious challenges to the efficacy of such a spectrum regime have arisen, however. Seeing the widespread adoption of such devices as cordless phones and wi-fi radios using bands set aside for unlicensed use, some scholars and policy makers posit that spectrum sharing technologies have become cheap and easy to deploy, mitigating airwave scarcity and, therefore, the utility of exclusive rights. This paper evaluates such claims technically and economically. We demonstrate that spectrum scarcity is alive and well. Costly conflicts over airwave use not only continue, but have intensified with scientific advances that dramatically improve the functionality of wireless devices and so increase demand for spectrum access. Exclusive ownership rights help direct spectrum inputs to where they deliver the highest social gains, making exclusive property rules relatively more socially valuable. Liberal licenses efficiently accommodate rival business models (including those commonly associated with unlicensed spectrum allocations) while mitigating the constraints levied on spectrum use by regulators imposing restrictions in traditional licenses or via use rules and technology standards in unlicensed spectrum allocations.
