Abstract:
1. A method for managing a segment threshold, comprising: (a) determining whether a packet has been transmitted to a predetermined terminal; (b) receiving from the predetermined terminal a response message indicating that the predetermined terminal has received the packet without any errors, if a packet has been transmitted to the predetermined terminal; (c) receiving signal intensity data of a current packet transmitted from the predetermined terminal; and (d) adjusting the segment threshold using the received signal intensity data of a current packet, if the response message has been received, wherein a segment threshold is calculated by performing a mathematical operation involving a current threshold value and the received signal intensity data of the current packet, wherein the mathematical operation represents setting the segment threshold to a smaller value between a predetermined maximum threshold value and a value obtained by multiplying a current segment threshold value by a value obtained by raising 2 to the power of the signal intensity level.
