The invention discloses an organization method of nodes in the wireless P2P network and a resource discovery method; the organization method comprises that: every node is at least included in a circle which takes the node IP address hash value as the index and a routing table is established for every circle which comprises the node; the routing tables are used for storing the IP addresses and IP address hash values of the nodes except for the nodes in the circle. The resource discovery method comprises that: an inquiry resource node implements hash conversion on the resource key word to be searched and inquires the forwarding node which is proximal to the hash value of the resource key word in every routing table; and then the forwarding node continues to inquire the forwarding node whichis proximal to the hash value of the resource key word in local routing tables until the destination node for storing the resource is found. By adopting the invention, every node is provided with a plurality of circles, thus
