ABSTRACT Current technology on the use of fifth generation (5 G) networks relies on IPv6 routing protocol (RPL) for low-power and lossy networks (LLNs). However, the constrained-resource nature of Internet of things (IoT) devices for LLNs makes RPL limited in routing functions and in need of enhancements in its objective functions (OFs) when selecting preferred parents (PPs) among nodes for optimized routing decisions while satisfying varied IoT applications requirements. We explore the vast application areas of LLNs and advances made in supporting operating system platforms as well as RPL enhancements. We observed that recent studies focus more on routing optimization for PPs selection in LLNs and node density management under varying traffic load, targeting a diversity of IoT applications requirement. Strengths and weaknesses in metrics adopted by literature are presented with suggestions to overcoming identified challenges. Evidently, the lack of real-time data has greatly declined ground-truth verification of RPL metric(s), demanding intelligent techniques for improved performance and meaningful connectivity scale up. This work proposed an integrated machine learning (ML) framework for RPL functionalities enhancement in IoT-based networks. Findings from the review revealed that using ML techniques could facilitate the deployment of several desired parameters for significant LLNs performance improvements.

ABSTRACT This paper is part of InterPARES Trust (IP Trust) four projects which is a multi-disciplinary and multinational research project that explores issues concerning digital records entrusted to the Internet worldwide. As part of the e-government transition in the public sector, Botswana is grappling with a change from manual recordkeeping practices to digital ones, where records might be supported by ICTs or generated within ICTs themselves. Digital records generated within and managed by Enterprise Content Management systems (ECMs) optimized for recordkeeping may require intervention both to be identified as records and integrated in a networked environment where they can be managed for effective e-government services. The paper draws on a bibliography of over 50 published articles in order to examine the state of enterprise-wide systems and ECM applications in the Botswana public service; determine their relationship (if any) to existing archives and records management (ARM) practices; and to contextualize these enterprise-wide systems and ECM applications with acknowledged ARM challenges in Botswana and Africa. It is hoped that the paper will provide evidence and lay the future foundation for the integration of ARM practice in the Botswana e-government drive.

ABSTRACT This paper provides an overview of issues around the authenticity of artworks and objects and their related archives, in the context of an organization’s art collection. Due to the high prices and cultural importance of significant objects and documents, it is important to manage risk. The digital age has led to a public keen on gaining virtual access to information, thus while a corporate collection indicates corporate social responsibility, it involves cultural memory and demonstrates public spending which calls for accountability, compliance with regulations and responsible management of the collection. What are the risks and how should these be managed?

ABSTRACT Records management plays a significant role in ensuring accountability, transparency and good governance. Chapter nine institutions, on the other hand, are democratic institutions responsible for the promotion of accountability, transparency and good governance in the public sector through various forms such as investigation, reporting, and recommendations. While the regulatory role of records management in the public sector is the responsibility of the National Archives and Records Service of South Africa (NASA), it would seem this responsibility is cumbersome for the organization as several scholars concur that the public sector is characterized by poor records management. As a result, NARSSA is unable to support governmental bodies in managing records properly. Given the position of the Auditor-General South Africa (AGSA) in government and its mandate as set out by the Constitution of the Republic of South Africa, this institution is able to hold the state accountable for their actions, unlike NARSSA. This qualitative study explores the contribution of the AGSA to records management in the public sector with the view to ensure accountability, transparency and good governance. Data were collected through interviews with purposively selected participants from the AGSA’s records management unit and external auditors. Furthermore, interview data were augmented with content analysis of documents such as acts, strategic plans, operational plans, audit reports, and annual reports. The study established that there is a working relationship between the AGSA and NARSSA through the memorandum of understanding signed by the two institutions. In addition, the AGSA organizes records management seminars annually to sensitize public servants about the importance of record keeping in support of auditing process. It is concluded that successful execution of the AGSA’s mandate relies on the availability of reliable and authentic records. As a result, the AGSA can contribute towards public sector records management by reporting cases of poor records management in government institutions to NARSSA, which in turn can assist the affected institutions in setting up the proper records management programme.

ABSTRACT The Integrated Archival Information System, ZoSIA, was created by the National Digital Archives in Warsaw as a unified platform for archival description and access, based on such international standards. The system is being developed (along with an information technology [IT] infrastructure) since 2007 and nowadays is the main archival data management tool used by the Polish Archives. The ZoSIA provides both a way to record descriptive information about archival holdings and a means to view, search, and browse that information. It used also as a tool for creating finding aids. The introduction of the ZoSIA affected archival practice, as well as reference services. The change was accelerated by the technology development and the appearance of electronic records. In 2016, the Central Committee for Archival Methodology made a conscious effort to adjust the process of establishing intellectual control over records through to the usage of Integrated Archival Information System.

ABSTRACT This introduction for this special issue on E-ARK and digital archiving sets out the rationale, objectives and work program carried out by the E-ARK project, a pan-European endeavour supported by the European Commission as part of their FP7 PSP CIP pilot B program to standardize and create tools for consistently transferring digital records between business systems and digital archives. The E-ARK project's segue into the eArchiving Building Block as part of the European Commission’s Connecting Europe Facility’s (CEF) Program is also detailed, together with an update on current activities. As part of the impetus for Open Data and transparent government, the E-ARK/eArchiving approach can be extremely effective in simplifying and making consistent, diverse approaches to solving the issue of how to transfer information between the ICT systems in use in, for example, government, and the archives charged with the responsibility for ongoing and management of the information considered to be of long-term significance. They are also applicable to a much wider range of situations where users need to archive digital material.

ABSTRACT Relational databases are one of the main technologies supporting information assets in today’s organizations. They are designed to store, organize and retrieve digital information, and are such a fundamental part of information systems that most would not be able to function without them. Very often, the information contained in databases is irreplaceable or prohibitively expensive to reacquire; therefore, steps must be taken to ensure that the information within databases is preserved. This paper describes a methodology for long-term preservation of relational databases based on information extraction and format migration to a preservation format. It also presents a tool that was developed to support this methodology: Database Preservation Toolkit (DBPTK), as well as the processes and formats needed to preserve databases. The DBPTK connects to live relational databases and extracts information into formats more adequate for long-term preservation. Supported preservation formats include the SIARD 2, created by a cooperation between the Swiss Federal Archives and the E-ARK project that is becoming a standard in the area. DBPTK has a flexible plugin-based architecture enabling its use for other purposes like database upgrade and database migration between different systems. Presented real case scenarios demonstrate the usefulness, correctness and performance of the tool.

ABSTRACT Wireless Interoperability for Multiple Access (WiMAX) is one of the emerging fields of high-speed wireless communication that has enormous capabilities due to its range and the connection speed. Like wireless local area networks (LANs), WiMAX networks implement multiple quality of service (QoS) frameworks at the Media Access Control (MAC) level for assured data, voice, and video services. The question of ensuring QoS is basically how to distribute available resources to users in order to satisfy QoS parameters such as latency, jitter and throughput requirements. IEEE 802.16 standard does not have any particular guidelines on scheduling of incoming and outgoing data. This has caught the attention of researchers working on WiMAX. This article discusses the various issues in WiMAX along with a classification of various scheduling approaches based upon the type of scheduler for the sake of better understanding the scheduling problem and analyzing various available theories.

ABSTRACT The utilization of Multiple Input Multiple Output – Orthogonal Frequency Division Multiplexing (MIMO-OFDM) has rapidly gained popularity because of its improved performance capabilities in terms of enhanced spatial diversity gain, reliability as well as the spatial multiplexing Gain. This paper discusses the effect of spatial correlation in Forward Error Correction of MIMO-OFDM system. Here, the four error correction codes, namely, Convolutional Code (CC), Low-Density Parity Check (LDPC-CC), and Reed-Solomon code (RSC-CC) is validated under three channel models, namely, Rayleigh, Rician and Additive White Gaussian Noise (AWGN). The analysis is performed using four modulation schemes such as Quadrature Phase Shift Keying (QPSK), Binary Phase Shift Keying (BPSK), Quadrature Amplitude Modulation (QAM)-16, and QAM-64. It is performed under three antenna configurations like 2 × 2, 2 × 4, and 4 × 4. Moreover, the Peak Signal to Noise Ratio (PSNR) is exploited to identify the image transmission, as well as the Bit Error Rate (BER), is exploited to identify the data transmission. In experimental results, the Turbo-CC displays better performance.
