Abstract. We define an out-degree for F-coalgebras and show that the coalgebras of outdegree at most form a covariety. As a subcategory of all Fcoalgebras, this class has a termin...
Abstract-- This paper introduces a novel concept from coalitional game theory which allows the dynamic formation of coalitions among wireless nodes. A simple and distributed merge ...
Abstract-- In this paper we propose a distributed authentication service for peer-to-peer (P2P) based massively multiuser virtual environments. Such a service is necessary to provi...
