|Résumé||I will present a generic scheme to transform a silent self-stabilizing 1-hop weight-based clustering protocol, called original protocol P, to a self-stabilizing with service guarantee protocol, called the transformed protocol TP. TP requires only 2 bits more than P. Moreover, starting from an arbitrary configuration, TP reaches a safe conguration in at most 3 rounds, where the following useful minimal service is provided: "each node belongs to a 1-hop cluster having an effectual leader". Afterwards, TP reaches a terminal configuration in at most 4*SP rounds where SP is the stabilization time of P protocol. During stabilization of TP protocol, the minimal service is preserved, so the clustering structure is available throughout the entire network.
