Wireless networks for sparsely populated rural areas of the Far North. Spatial pattern optimization of the developed wireless network based on the variant probability method. The problem of choice of place for access points of the growing network.
In this work, we consider a method of searching of the direction of a wireless network development (the places of new access points or base stations etc.) optimized with criteria of coverage of important territories and minimum cost of equipment and additional needed infrastructure which does not need any special field testing and determination of the exact geometry of elements of radio propagation medium and their RF absorbing properties but takes into account the minimum accessible information obtained from built-in measuring instruments of wireless hardware and approximate data of the medium elements shape. The problem of search of a disposition and types of the infrastructure elements of the growing network is formulated as a multi-criteria discrete constrained optimization problem solvable with variant probability method [1]. The problem of a radio propagation medium properties modeling is also formulated and solved as a discrete optimization task. RELATED WORKS The considered problem of optimal access points placement is often a subject of the engineers and network administrators in the Internet forums and scientific publications. Some of them offer ready-to use software able to forecast the signal coverage in accordance with the physical properties of the environment elements. Other scientific works offer various methods of search of new access points placement with optimal signal coverage [2, 3] or (come complex case) placement which provides for the best localization of a mobile WLAN equipment position (calculation of its coordinates) within the area of coverage of the network [4, 5].
