Wireless network finds application in communal facilities monitoring and management systems. One of the basic requirements for the construction of a wireless monitoring network with autonomous power supply is the guaranteed network lifetime. Up-to-date challenges in the field of wireless monitoring networks are creation of universal hardware platforms that allow for usage of widespread proprietary transceivers of different manufacturers aiming at creating network topologies raising energy efficiency and lifetime of WMN. The article describes a model of a wireless network allowing evaluation of its lifetime by energy parameters and dynamic reconfigurations induced by external influence. On the basis of the represented test results one may conclude that energy consumption is defined by the level of the application stack of the protocol ZigBeе and doesn’t depend on PHY and MAC layers of the protocol 802.15.4. Considering energy consumption of the data transmission process, potential increase in the lifetime of the devices and network as a whole is mostly controlled by the sizes of useful messages.

The article presents methodology of business processes reengineering (BPR) in the modern construction organizations adapted to dynamically changing conditions of the internal and external environment. The ontological analysis carried out in the article allowed to distinguish the dominant characteristics of business process reengineering (BPR) as a phenomenon and a target project. It was justified to consider reengineering through the following dominants: mandatory for reengineering format of a temporary specialized project of local or cardinal transformations; the main goal of BPR is to direct the transformation of business processes, operational and production and administrative systems of the enterprise - for their joint reconfiguration to ensure a sharp increase in competitiveness of the studied enterprise (among similar enterprises in actually occupied or potential markets ; increase in the functional quality of production and administration processes, which will ultimately ensure a significant increase in the quality of the operating system of the enterprise and a proper increase in its resilience to crises (destruction, loss of economic balance and financial stability, bankruptcy, etc.). Formalization of the BPR methodology ensures the combination of reverse and direct reengineering stages. The results of the study allow solving urgent problems of increasing the competitiveness of construction organizations through reengineering design. The scientific significance of the study lies in the development of a component methodology for modeling reengineering of business processes. The practical significance of the use lies in the application of the study in the real sector of the economy during the restructuring and reform of construction organizations. The scientific novelty of the study lies in the development of a methodology and conceptual provisions for systemic management of business process reengineering of building organizations based on the use of the process approach.
