The invention discloses a method for selecting matrix wireless sensor network-oriented random routing, which comprises the steps that: (1) a network randomly selects sensor nodes in the network to be nodes for a data packet to be sent according to the set probability; (2) the nodes for the data packet to be sent selectively receives the next hop node of the data packet by judging whether the node number is N, the node belongs to which interval or whether the node can be divided exactly; (3) the node for the data packet to be sent transmits the data packet to the selected next hop node, after receiving the data packet, the next hop node judges whether the number of the next hop node per se is present in the number information of the data packet so as to update the data packet received by the next hop node or use the received data packet as the data packet to be sent of the next hop node, and the step (2) is executed by taking the next hop node as the node for the data packet to be sent in the next path selection; and (4) the data packet is received by convergent nodes, and the random routing selection is finished.
