Abstract

Embodiments of the invention provide a method, system and computer program product for detecting isolated group members. The method includes defining in memory of a master computer, a group of individuals each with a corresponding one of a multiplicity of registered mobile devices. The method also includes collecting in the master computer geographic location data for each of the mobile devices along with an effective line of sight with others of the individuals. The method yet further includes computing a coefficient of isolation for each of the individuals based upon the collected geographic location data and the determination of an absence or presence of an effective line of sight with different other individuals in the group, each of the coefficients indicating a degree of isolation of a corresponding one of the individuals. Finally, the method includes storing the coefficients in a table.
