Abstract
A method and apparatus for controlling power of a transmitter in a mesh network. A controller, if it sets a reference power to one of a first measured transmission power and a maximum power, compares the reference power with a first power in level, and compares the first power with a second power in level. A cumulation factor calculator calculates a cumulation factor by comparing the first power with the second power. A reference power setter sets the reference power according to a scope to which a value obtained by adding a reference power to a sum of the calculated cumulation factors belongs. A power controller controls transmission power according to the set reference power.
Claims25
A method for controlling power of a transmitter in a mesh network, the method comprising:
- calculating cumulation factors to estimate a distance between the transmitter and a different transmitter, the calculating of the cumulation factors comprising repeatedly comparing a first power with a second power, the first power being a currently measured transmission power, the second power being transmission power measured a predetermined time in advance of the first power;
- setting a reference power to one of a first measured transmission power and a maximum power;
- and
- controlling transmission power based on the estimated distance according to a scope to which a value obtained by adding a predetermined reference power to a sum of the calculated cumulation factors belongs.
An apparatus for controlling power of a transmitter in a mesh network, the apparatus comprising:
- a reference power setter configured to set a reference power to be one of a first measured transmission power and a maximum power;
- a controller configured to compare:
- a reference power with a first power, the first power being a currently measured transmission power;
- and
- the first power with a second power, the second power being a transmission power measured a predetermined time in advance of the first power;
- a cumulation factor calculator configured to estimate a distance between a transmitter and a different transmitter by calculating cumulation factors, the cumulation factors being calculated by repeatedly comparing the first power with the second power;
- and
- a power controller configured to control transmission power based on the estimated distance according to a scope to which a value obtained by adding the set reference power to a sum of the calculated cumulation factors belongs.
