Blockchain-Based Distributed Energy Trading in Energy Internet: An SDN Approach

The new network paradigm of Software Defined Networking (SDN) has been widely adopted. Due to its inherent advantages, SDN has been widely used in various network fields such as data centers, WAN, enterprise, Optical Networks and energy Internet. Among them, SDN-based energy Internet systems are receiving more and more attention. But at the same time, some problems and challenges are gradually becoming more prominent. The SDN-based energy Internet is a distributed architecture for renewable energy, so the traditional centralized electric energy trading model will no longer apply. The blockchain has been rapidly developed and applied in various domains by virtue of its decentralization, coordinated autonomy, and non-tamperability. We propose an SDN-based energy Internet distributed energy trading scheme supported by blockchain technology. The proposed scheme achieves a reasonable match of the transaction objects under the premise of protecting privacy. Finally, we conducted a comprehensive, systematic security and applicability analysis of the proposed solution, further confirming that the system meets our design goals. - 2013 IEEE.This work was supported in part by the Beijing Natural Science Foundation under Grant 4182060, in part by the National Natural Science Foundation of China under Grant 61972148, and in part by the Fundamental Research Funds for the Central Universities under Grant 2019MS020.Scopu

Addressing Security issues for Enterprises Migrating to HYBRID Cloud Computing Model

Although on premises deployment has been a reliable platform to deploy in house applications & production software’s like email, ERP, Web servers, database for long, but managing the datacenter, applications, & specially the upgrade path for the newer version of software was always a challenge for the enterprises. Today, considering the rapid growing market of cloud computing, many organizations are keen to adopt the cloud platform. Cloud computing technology drawn the attention of IT world and is now days changing the focus of enterprises too. DOI: 10.17762/ijritcc2321-8169.15062

Critical success factors in the design of suitable oncology platforms

Cancer, a chronic disease has become one of the primary causes of death in advanced countries. The diagnosis, medication and treatment for cancer is very expensive. Healthcare providers, especially in cancer care, need to automate and accelerate access to patient data and evidence based decision making along with greater quality control and safety. Oncology information systems (OIS) provide a simple solution for this. This study compared 3 different leading international oncology information systems capable of delivering high-value, patient centred care to cancer patients in the Australian context. This work analysed functionality, usability and interoperability of these systems for the Australian healthcare environment and their integration with existing systems and assets. Critical success factors in the design of platforms to make them perform better from clinicians’ and patients’ points of view have also been discussed

Digital watermarking: a state-of-the-art review

Digital watermarking is the art of embedding data, called a watermark, into a multimedia object such that the watermark can be detected or extracted later without impairing the object. Concealment of secret messages inside a natural language, known as steganography, has been in existence as early as the 16th century. However, the increase in electronic/digital information transmission and distribution has resulted in the spread of watermarking from ordinary text to multimedia transmission. In this paper, we review various approaches and methods that have been used to conceal and preserve messages. Examples of real-world applications are also discussed.SANPAD, Telkom, Cisco, Aria Technologies, THRIPDepartment of HE and Training approved lis

The adoption of cloud computing by SMEs: identifying and coping with external factors.

Comunicação apresentada na CAPSI 2011 - 11ª Conferência da Associação Portuguesa de Sistemas de Informação – A Gestão de Informação na era da Cloud Computing, Lisboa, ISEG/IUL-ISCTE/, 19 a 21 de Outubro de 2011.The recent development of Cloud Computing (CC) provides a convincing opportunity for organizations to outsource their Information and Communications Technology (ICT). Although its popularity is increasing rapidly, there are concerns that must be taken into account. This paper ascertains the most relevant issues associated with the political, economic, social and technological factors concerning CC adoption. The research described is based on a scoping review to identify relevant studies published in the literature recently. The aim is to provide an overview of the most recent findings in the Cloud Computing environment, which can inform strategic decision-making by Small to Medium-sized Enterprises (SMEs) in this area

Performance Evaluation of Bonding Techniques at Wireless 802.11n

Demands for high throughput bandwidth, encourage Point to Point wireless to serve more bandwidth for many kind application such as real-time multimedia services. We conduct research with testbed experimental at Point to Point topology use wireless 802.11n in LAB environment. The aim is to studying the performance that would be achieved by Interface Bonding and Channel Bonding techniques. We proposed experiment process and design to evaluate the performance of those techniques. Several parameters such as delay, jitter, data loss rate and throughput applied on TCP/UDP protocols with different Packet Sizes and Directional Traffic Flows. The results experiment showed that Channel Bonding has significant throughput improvement. However, the Interface Bonding results are far from expectation, we found that the performance is least than single normal link. As our finding we analyze it caused by Media Independent Interface (MII), and Scheduling Algorithm unable to work properly at wireless 802.11n using Point to Point connection
