In a wireless network, an user has the possibility of remaining link while moving in a more or less spread geographical perimeter, it is the reason for which they intend to sometimes speak about "mobility". The wireless Grid represent a new type of network of distribution of means linking up mobile phones and other implements of edge some with the others with different access points. In this article, we offer a service allowing to manage the consistency of the replicas of data in such environment where the users can move at any time. Offered service combines between optimistic and pessimistic approaches. We go shown with the aid of several results of experimentation which our proposal allows to reduce in a remarkable manner the number of divergences and conflicts between replicas of the same data in environment Wireless Grid.
