Method for calculating numerical characteristics of two devices interference for device-to-device communications in a wireless heterogeneous network

In wireless networks, one of the key performance metrics is the signal to noise ratio, SINR. As this metric highly depends on the distance between the interfering devices, the problem of SINR estimation is often reduced to the calculation of a triangle's side length, where the vertices represent the interacting devices. This paper addresses the problem of calculating the numerical characteristics of the signal to interference ratio for a pair of interfering devices determined by the known distributions of distances between the entities in question. The proposed method can be used as a basis for analyzing heterogeneous networks, including the analysis of device-to-device (D2D) communications as one of the interference-limited cases.
