1. A method for channel resource management performed by a first communication node in a communication system, the method comprising:
monitoring channel information broadcast packets transmitted from other communication nodes;
receiving a first broadcast packet, which is a channel information broadcast packet transmitted from a third communication node that is included in the other communication nodes and performs one-to-one communication with a second communication node included in the other communication nodes; and
managing a one-to-one channel resource for one-to-one communication with a fourth communication node included in the other communication nodes based on information included in the first broadcast packet,
wherein
the first broadcast packet includes information on a first one-to-one channel resource allocated for one-to-one communication between the second and third communication nodes,
wherein the managing of the second one-to-one channel resource comprises:
allocating the second one-to-one channel resource corresponding to a one-to-one channel resource for one-to-one communication directly with the fourth communication node;
re-monitoring channel information broadcast packets transmitted from other communication nodes;
receiving a second broadcast packet, which is a channel information broadcast packet transmitted again from the third communication node; and
determining whether reallocation of the second one-to-one channel resource is required based on information included in the second broadcast packet,
wherein the second broadcast packet includes information on a third one-to-one channel resource used for one-to-one communication directly between the second and third communication nodes at a time at which the second broadcast packet is transmitted,
wherein the second broadcast packet further includes location information of the second communication node and location information of the third communication node at the time at which the second broadcast packet is transmitted, and the determining of whether reallocation of the second one-to-one channel resource is required comprises:
comparing the second one-to-one channel resource with the third one-to-one channel resource;
in response to determining that the second one-to-one channel resource and the third one-to-one channel resource are same, identifying a distance between a first node pair comprising the second and third communication nodes and a second node pair comprising the first and fourth communication nodes based on the location information of the second communication node and the location information of the third communication node;
comparing the distance between the first node pair and the second node pair with a first threshold distance; and
in response to determining that the distance between the first node pair and the second node pair is less than or equal to the first threshold distance, determining that reallocation of the second one-to-one channel resource is required.
