Data collection algorithm for wireless sensor networks using collaborative mobile elements

The simplest approach to reduce network latency for data gathering in wireless sensor networks (WSN) is to use multiple mobile elements rather than a single mobile sink. However, the most challneging issues faced this approach are firstly the high network cost as a result of using large number of mobile elements. Secondly, it suffers from the difficulty of network partitioning to achieve an efficient load balancing among these mobile elements. In this study, a collaborative data collection algorithm (CDCA) is developed. Simulation results presented in this paper demonstrated that with this algorithm the latency is significantly reduced at small number of mobile elements. Furthermore, the performance of CDCA algorithm is compared with the Area Splitting Algorithm (ASA). Consequently, the CDCA showed superior performance in terms of network latency, load balancing, and the required number of mobile elements

Efficient Cluster Heads Selection Based on Index-Modulation in Wireless Sensor Networks

Index-Modulation (IM) has been recently emerged as a promising direction towards improving error performance and spectral efficiency in wireless networks. To this end, IM-based Wireless Sensor Networks (IM-WSN) has been recently applied as a decision gathering scheme in clustered Wireless Sensor Networks, by which a significant improvement in the decision error rate (DER) is achieved. Later, following the same IM principle, efficient IM-WSN scheme (EIM-WSN) has been introduced, but with the emphasis on reducing the computational complexity of IM-WSN while improving the error performance. Although in these schemes cluster heads (CHs) vary dynamically, still they suffer from the unfair distribution of the CH role among nodes. As a result, nodes energy will be unequally dissipated, and hence the network lifetime will be deteriorated. In this study, aiming at balancing the CH role among cluster nodes, a new decision reporting scheme, namely index-shift, is proposed. The performance of proposed scheme is analysed in terms of DER and network lifetime and compared with the previous IM reporting schemes, IM-WSN and EIM-WSN. Analytical and simulation results show that the proposed scheme demonstrates fair distribution of CH role among all cluster nodes. This, in turn, led to extend the network lifetime up to 50% compared to other schemes, in addition to acheive DER that is better than IM-WSN and almost identical to EIM-WSN

Sustainable transformation of accounting in agriculture

Purpose. The purpose of the article is to model the paradigm of accounting and reporting development in the context of the sustainable agricultural enterprise. Methodology / approach. In the process of working on the article, general scientific methods and methodological techniques were used, in particular, monographic and system analysis (formation of accounting information to take into account sustainable development); methods of comparative analysis (when studying the transition from a traditional accounting system to sustainable accounting); grouping (for grouping accounting types by user groups and information); structural-and-logical compilation (when formulating the conceptual foundations of information to take into account sustainable development); modeling (when building a model of the concept of sustainable accounting and a map of internal and external stakeholders of the enterprise in terms of the level of influence, interest and direction of the formation and use of reporting information); process approach (when developing a paradigm for the development of enterprise reporting in the field of sustainable development); abstract-logical (theoretical generalization and formation of conclusions); graphical method (with a visual display of economic phenomena and processes in time and space); system-functional (to generalize the theoretical and methodological aspects of sustainable development accounting). These methods were the methodological basis of the study. Results. To determine the category of sustainability accounting and the concept of its reporting, the types of entrepreneurial capital were studied, and the characteristics of information that arises as a result of the implementation of economic, social, and environmental activities. In addition, the main users of information, their goals, and their needs were identified. As a result, management and financial accounting for sustainable development were highlighted. The functioning of the institution of sustainable development reporting of agricultural enterprises is based on its "paradigm" as a set of generalized ideas, hypotheses, and methodological approaches shared by the scientific community, acceptable to other institutions, and formalized in the form of scientific theories. In the case when, within the framework of existing theoretical postulates, a scientific institute cannot effectively solve the issues, there is a need to change its paradigm. The proposed paradigm of accounting and reporting will not only orient the development of accounting to the prospects for the transition of mankind to a harmonious economy but also facilitate the acceleration of this transition through the introduction of progressive accounting systems. Originality / scientific novelty. Due to all findings and conducted research in modeling a new system of accounting and reporting for agricultural enterprises we could generate the definition of “sustainability accounting”, which, on the one hand, the segmental, and on the other – the organic component of the enterprise accounting system and the institution of accounting in socio-economic relations, which is organized at the request of the policy of sustainable development, has a corresponding theoretical, methodological and organizational methodological support and is identified in accounting policy, operational, statistical and financial reporting, which provides an organizational and methodological focus on the construction of such accounting by enterprises. Practical value / implications. The main provisions of the article are brought to the level of methodological generalizations and applied tools, the use of which allows adopting a new holistic concept for the formation of accounting and analytical support for the sustainable development of the institutional units of the agrarian sector. The recommendations outlined in the article are fully consistent with modern trends in the development of socio-ecological and economic relations in society, therefore, they can be used in the formation of modern institutional accounting methodology in the context of sustainable development
