Abstract:
1. A method of selecting a relay node, the method being performed by a predetermined node, comprising: updating a neighbor node list based on messages received from one or more other nodes; selecting a 1-hop neighbor node having a highest Multi-Point Relay (MPR) selector counter (MSC) value, from among one or more 1-hop neighbor nodes included in the updated neighbor node list, as an MPR node, where the MSC value denotes a number of the 1-hop neighbor nodes that selected the predetermined node as the MPR node; aligning one or more 1-hop neighbor nodes included in the updated neighbor node list depending on MSC values; and aligning the one or more 1-hop neighbor nodes depending on a number of neighbor nodes of each of the 1-hop neighbor nodes included in the neighbor node list and aligned depending on the MSC values, wherein updating the neighbor node list comprises: wherein the selecting the 1-hop neighbor node having the highest MSC value, from among the one or more 1-hop neighbor nodes, as the MPR node is configured to select a 1-hop neighbor node having a highest MSC value and a largest number of neighbor nodes, from among the one or more 1-hop neighbor nodes, as the MPR node.
