A method of information distribution for use in a wireless communication system comprising a propagator node comprising first and second neighbor interface modules (341, 342), the method executed by the propagator node and comprising: receiving a selection request signal over the second neighbor interface module of the propagator node, wherein the selection request signal has been sent by a selector node, wherein the method further comprises, if the selection request signal has been marked as a persistent selection request, storing, in a selection routing table: a persistent selection tag of the selection request signal, and an identifier of the second neighbor interface module; receiving an information advertisement signal over the first neighbor interface module of the propagator node, wherein the information advertisement signal has been sent by a distributor node, wherein said information advertisement signal identifies information available from said distributor node, and wherein said first neighbor interface module is directly or indirectly associated with said distributor node; storing, in a distributor routing table: a distributor tag of said information advertisement signal by said propagator node, and an identifier of the first neighbor interface module; determining that all or a portion of said persistent selection tag in said selection routing table matches all or a portion of said distributor tag of said information advertisement signal in said distributor routing table, and in case of a positive match: forwarding said selection request signal comprising said matching persistent selection tag towards the distributor node via the first neighbor interface module. receiving a selection request signal over the second neighbor interface module of the propagator node, wherein the selection request signal has been sent by a selector node, wherein the method further comprises, if the selection request signal has been marked as a persistent selection request, storing, in a selection routing table: a persistent selection tag of the selection request signal, and an identifier of the second neighbor interface module; receiving an information advertisement signal over the first neighbor interface module of the propagator node, wherein the information advertisement signal has been sent by a distributor node, wherein said information advertisement signal identifies information available from said distributor node, and wherein said first neighbor interface module is directly or indirectly associated with said distributor node; wherein said information advertisement signal identifies information available from said distributor node, and wherein said first neighbor interface module is directly or indirectly associated with said distributor node; storing, in a distributor routing table: a distributor tag of said information advertisement signal by said propagator node, and an identifier of the first neighbor interface module; determining that all or a portion of said persistent selection tag in said selection routing table matches all or a portion of said distributor tag of said information advertisement signal in said distributor routing table, and in case of a positive match: forwarding said selection request signal comprising said matching persistent selection tag towards the distributor node via the first neighbor interface module.
