I believe that ICS telecom / ICS designer software developed by ATDI can provide sufficient information on neighbor overlapping in any wireless network of your choice.
features:
Manages most of wireless technologies from 8kHz to 350GHz
Supports more than 50 propagation models (including ITU, 3GPP, COST, NTIA…) and a dedicated API (C/C++/C#) .
Has accurate propagation engine, which features radio-localization: angle of arrival (AOA), time difference of arrival (TDOA), RSSI and hybrid (combination of AOA, TDOA and RSSI). Features also include multilateration and monitoring sensor efficiency maps.
No, Community detection is an important task in network analysis. A community (also referred to as a cluster) is a set of cohesive vertices that have more connections inside the set than outside. In many social and information networks, these communities naturally overlap. For instance, in a social network, each vertex in a graph corresponds to an individual who usually participates in multiple communities
