We described the placing of the mobile agents in a dynamic environment. It formed a dynamic environment for a complex of dynamically changing mobile agents. We described a two-level system of connections at the global and local levels of interaction. Such a scheme allows you to support the survivability of a dynamic environment. We presented the model of placement of mobile agents in a dynamic environment, which forms the basis of the trajectory of interaction between mobile agents, enabling us to combine the dynamic environment into a unified dynamic environment. The proposed method for mobile agents parameters restoring in a unified dynamic environment, taking into account the similarity coefficients, allows restore 80% parameters of an inaccessible mobile agent. This indicates the high efficiency of the objects description in the form of a unified dynamic environment in order to maintain its integrity.

Method of Parallel Information Object Search in Unified Information Spaces

By Alexander Dodonov Vadym Mukhin Valerii Zavgorodnii Yaroslav Kornaga Anna Zavgorodnya Oleg Mukhin

DOI:, Pub. Date: 8 Aug. 2021

The article describes the concept of a unified information space and an algorithm of its formation using a special information and computer system. The process of incoming object search in a unified information space is considered, which makes it possible to uniquely identify it by corresponding features. One of the main tasks of a unified information space is that each information object in it is uniquely identified. For this, the identification method was used, which is based on a step-by-step analysis of object characteristics. The method of parallel information object search in unified information spaces is proposed, when information object search will be conducted independently in all unified information spaces in parallel. Experimental studies of the method of parallel information object search in unified information spaces were conducted, on the basis of which the analysis of efficiency and incoming objects search time in unified information spaces was carried out. There was experimentally approved that the more parameters that describe the information object, the less the time of object identification depends on the length of the interval. Also, there was experimentally approved that the efficiency of the searching of the incoming objects in unified information spaces tends to a directly proportional relationship with a decrease in the length of the interval and an increase in the number of parameters, and vice versa.

Method of Restoring Parameters of Information Objects in a Unified Information Space Based on Computer Networks

By Vadym Mukhin Valerii Zavgorodnii Oleg Barabash Roman Mykolaichuk Yaroslav Kornaga Anna Zavgorodnya Vitalii Statkevych

DOI:, Pub. Date: 8 Apr. 2020

The paper describes the organization of the unified information space which is based on the uniform principles and the general rules that ensure the informational interaction of objects.
In practice, in case when the communication with an information object of the unified information space is lost, the necessary information about this object should be collected by the analysis of previous interactions of the information object with the other information objects. The goal of this paper article is to develop a mechanism that will allow restore the missing parameters of information objects in case of communication loss with this object.
There was performed the experimental researches with the proposed mechanisms. The experiments have shown that there is an unequivocal relationship between the quality of restoration of an information object and the topology of links within an unified information space.
