A method of information distribution for use in a wireless communication system comprising a propagator node comprising first and second neighbor interface modules , 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 . <EOS>
