Claim:
1. A method for issuing information comprising establishing an ad hoc network including an information issuing node and a client node, the method further comprising: when a user to which the information issuing node is attributive desires to issue information, storing, by the information issuing node, information issued by the user, broadcasting the information issued by the user to the ad hoc network and notifying all other nodes of the ad hoc network to update information of the information issuing node; wherein the method further comprises: when a new information issuing node is added into the ad hoc network, acquiring and storing, by the new information issuing node, information issued by users to which all information issuing nodes of the ad hoc network are attributive through transmitting an information acquisition request to a node connected therewith in the ad hoc network; wherein the acquiring, by the new information issuing node, information issued by users to which all information issuing nodes of the ad hoc network are attributive through transmitting an information acquisition request to a node connected therewith in the ad hoc network comprises: transmitting, by the new information issuing node, an information acquisition request to a node connected therewith in the ad hoc network, returning, by a node receiving the information acquisition request, information stored therein to the new information issuing node, and after determining that the information stored therein is part of the information issued by users to which all information issuing nodes of the ad hoc network are attributive, modifying a scope of information desired to be acquired in the received information acquisition request and forwarding the modified information acquisition request to a next node directly connected therewith; determining, by the next node, whether itself stores all information desired by the received information acquisition request according to a scope of information desired to be acquired in the received information acquisition request, after determining itself stores part of information desired by the received information acquisition request, returning to the new information issuing node part of information desired by the received information acquisition request and stored therein through forwarding by a routing node, modifying the scope of information desired to be acquired in the received information acquisition request and forwarding the modified information acquisition request to a further next node directly connected therewith, and so on until the new information issuing node acquires the information issued by users to which all information issuing nodes of the ad hoc network are attributive; and comparing, by the new information issuing node, ID numbers and issuing time of all received information so as to obtain newest information issued by users to which all information issuing nodes of the ad hoc network are attributive.
