Resumen
Currently, mobile devices such as smartphones and tablets are widely used. The computing power of their processors is comparable to the characteristics of personal computers, and this makes it possible to perform complex resource-intensive calculations on them. In the field of IoT, Raspberry Pi microcomputers are very popular. The paper explores the possibility of building a computing cluster from smartphones with Android OS and Raspberry Pi microcomputers. The article presents the results of testing the practical implementation of a distributed system, the nodes of which use heterogeneous smartphones. The computational capabilities of the system are determined and the applicability of static load balancing of nodes to improve the efficiency of computations is proved. The results obtained can be useful to a wide range of specialists.
