Apparatus and method for reducing power consumption in ad-hoc network

A power consumption reducing method comprising:

• (a) converting in each awake period, an inactive state into an active state as a converted active state, wherein power consumption is greater in the active state than in the inactive state;
• (b) receiving, in the converted active state, a beacon frame as a received beacon frame;
• (c) when the beacon frame is received in the step (b), and if an interval value of an awake window, in which the active state is maintained for a predetermined time, among field values of the received beacon frame is valid, setting the awake window as a set awake window;
• (d1) counting the interval value in the set awake window;
• and
• (e) if the counting is finished in the step (d1), converting the awake window into the inactive state.

A computer readable medium having embodied thereon a computer program for enabling a computer to provide a service of reducing power consumption, the service comprising:

• (a) converting in each awake period, an inactive state into an active state as a converted active state, wherein power consumption is greater in the active state than in the inactive state;
• (b) receiving, in the converted active state, a beacon frame as a received beacon frame;
• (c) when the beacon frame is received in the step (b), and if an interval value of an awake window, in which the active state is maintained for a predetermined time, among field values of the received beacon frame is valid, setting the awake window as a set awake window;
• (d1) counting the interval value in the set awake window;
• and
• (e) if the counting is finished in the step (d1), converting the awake window into the inactive state.
