Given a communication situation, consisting of a coalitional game and a graph, both defined on the same set of players-nodes, cohesiveness of a subset is defined as the proportion of their worth that the players in subset retain, when the originally deterministic (restricted) graph becomes a probabilistic one (in a specific manner). Conditions on the game are given to reach some desirable properties.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article1572-9338http://doi.org/10.1007/S10479-007-0247-4https://link.springer.com/article/10.1007/s10479-007-0247-4restricted access519.813519.876.3004.78:316.77Social networksCohesiveness measuresMyerson gameTeoría de JuegosInvestigación operativa (Estadística)1207.06 Teoría de Juegos1207 Investigación Operativa
