Transmission of information in automated special purpose systems

Abstract

This paper is devoted to solving the problem of optimizing the message transport service, which is one of the basic for automated special purpose systems. The NATO model of network-centric transformation of automated control and communication systems, which is presented in the form of a general plan for the development of information systems, was taken as the basis for the construction of special-purpose systems. An analysis of the development of information systems was carried out within the framework of the program of modernization and improvement of automated management systems. Under this program, large-scale work was carried out on the creation of new mobile nodes and means of communication for the perspective automated communication system at the tactical level Warfighter Information Network-Tactical. Therefore, it is proposed to use wireless, decentralized, mobile IP networks such as MANET (Mobile Ad hoc Network) for automated special purpose systems at the tactical level. Each of the mobile devices of such network can move independently in any direction, and, as a result, often break and establish connections with neighbors. For the MANET network the messaging service is considered in the context of: one automated workplace, one domain and interconnection between domains. The efficiency of information transmission systems is considered. Circular transmission algorithms for messages with the highest urgency category are defined and a control algorithm is provided for selecting the optimal message transmission channel in which the time spent on message transmission between these subscribers is minimal (dynamic programming problem with additive effect function). Bellman's functional equation for the conditional optimization stage was adapted for this problem.
