Below will be according to foregoing invention principle of the present invention, introduce in detail three embodiment the main principle that realizes of the inventive method is explained in detail and is illustrated.
Embodiment mono-
Power back-off node is as host node, for judging whether other nodes can enter power save mode and determine the time that enters power save mode in the present embodiment.Comprise that from node group at least one is default as the energy-conservation node from node, send for asking to enter the request message of power save mode to host node in the time that self meets the predetermined condition that enters power save mode from node, and determine when and enter power save mode according to the feedback of host node.
Please refer to accompanying drawing 3, is the schematic network structure of the embodiment of the present invention.Wherein host node S is power back-off node, and predetermined node A, Node B, node C from node group possesses the energy-conservation node that enters power save mode function, and node A, Node B, node C can be the node of the adjacent same wireless access module in overlay area.Node D is the node of the different radio access module adjacent with node A overlay area.
Please refer to accompanying drawing 4, is the flow chart of network energy-saving method in the embodiment of the present invention, and the whole flow process that enters power save mode taking node A request is here introduced network energy-saving method as example.
Whether step 401, meet the predetermined condition that enters power save mode from node A monitoring self, if enter step 402;
The predetermined condition that enters power save mode includes but not limited to:
Load is lower than predetermined threshold, or
Described power back-off node can be born this load from node, should from node can by and power back-off node between regularly mutual heartbeat message determine that can power back-off node bear this load from node.
Step 402, sends the request message for asking to enter power save mode from node A to host node S;
Step 403, host node S receives the request message of sending from node A, described in judging whether to allow, enters power save mode from node A, if so, enters step 404, otherwise enters step 407;
Here host node S by judge in the case of from node group from node all in normal operating conditions, while receiving the request message of sending from node A, all request messages of sending from node (from node A, from Node B, from node C) from node group whether are received, if so, allow to enter power save mode from node group; Otherwise, do not allow to enter power save mode from node group.
Step 404, host node S sends acknowledge message to each from node group from node (from node A, from Node B with from node C), enters step 405;
Step 405, host node S determines that according to the acknowledge message sending in step 404 energy-conservation node enters the time of power save mode, to strengthen transmitting power on this time, to respectively cover compensation from the former overlay area of node (from node A, from Node B with from node C) from node group;
Send the node of acknowledge message or other nodes of receiving the confirmation message according to acknowledge message, determine that the time that energy-conservation node enters power save mode mainly contains two class modes:
Mode one: explicit way: first the node (being the power back-off node S as host node in the present embodiment) that sends acknowledge message determines the time that enters power save mode, and in acknowledge message, carry temporal information corresponding to time of determining, send the node of acknowledge message if the words of power back-off node, on the time that enters power save mode of determining, carry out power back-off, send the node of acknowledge message if energy-conservation node enters power save mode on this time that enters power save mode of determining;
The node that receives the confirmation message extracts the temporal information of carrying from acknowledge message, is power back-off node if receive the confirmation the node of message, on time corresponding to the temporal information of extracting, covers compensation; If receiving the confirmation the node of message is energy-conservation node, and enters power save mode on time corresponding to this temporal information;
Obviously standard time corresponding to the temporal information in acknowledge message should be in current time (sending the time of acknowledge message) afterwards in predetermined amount of time, for example, suppose that current time is 18:00 on May 5th, 2000, time corresponding to this temporal information is 18:05 on May 5th, 2000, can be arranged flexibly according to real network situation by administrative staff, the time that this temporal information is corresponding and the difference of current time are too short, be difficult to ensure after experience time of expending of Internet Transmission, each energy-conservation node can be at this moment between before received acknowledge message; Certainly, the time that this temporal information is corresponding and the difference of current time long (for example 5 hours), otherwise load state probably changes already, enters power save mode and also just lost meaning.
Mode two: implicit: the node (being the power back-off node S as host node in the present embodiment) that sends acknowledge message does not carry temporal information in acknowledge message, the node that sends the node of acknowledge message or receive the confirmation message is respectively according to the rule of determining in advance the time that enters power save mode with the time according to sending or receive the confirmation message of other node agreements, determine the time that enters power save mode, and on this time, cover compensation or enter power save mode.For example, power back-off node and other energy-conservation nodes are made an appointment in the present embodiment: the node that sends acknowledge message covers compensation after the amendment cycle that sends the predetermined quantity after this acknowledge message, and the node that simultaneously receives the confirmation message enters power save mode after the amendment cycle that receives the predetermined quantity after this acknowledge message, or the node that sends acknowledge message for example, covers compensation on the scheduled time node (sending the integral point after acknowledge message) sending after this acknowledge message, the node that simultaneously receives the confirmation message for example, enters power save mode on the scheduled time node (receiving the confirmation the integral point after message) receiving after this acknowledge message, for instance, the timing node of making an appointment be between integral point and integral point every the time point of 10 minutes, be 8:00:00, 8:10:00, 8:20:00, 8:30:00, 8:40:00, 8:50:00, 9:00:00, power back-off node S has sent acknowledge message at 8: 02, from node A, from Node B and from node C respectively at 8: 03, 8: 04, within 8: 05, receive acknowledge message, host node S will cover compensation at 8:10:00 so, simultaneously from node A, all enter power save mode at 8:10:00 from Node B with from node C.
Step 406, from node A, from Node B with after node C receives the acknowledge message that host node S sends step 404, determines the time that enters power save mode, and enter power save mode on this time of determining according to this acknowledge message;
Step 407, host node S is to sending and wait notice from node A;
Step 408, keeps normal operating conditions from node A, waits for and receives the acknowledge message that described host node is sent, judgement receives the confirmation message, or occur that self does not meet the situation of the predetermined condition that enters power save mode, if the message of receiving the confirmation enters step 406; If before receiving the confirmation message, there is self not meeting the situation of the predetermined condition that enters power save mode, enter step 409;
Step 409, sends the message of cancelling for cancelling described request message that step 402 sends from node A to described host node S;
Step 410, host node S receives cancelling message of sending from node A in step 409, the request message that delete step 403 receives, cancel to described from node group each from node send acknowledge message.
Preferably, in step 406, before entering power save mode from node A, send the Indication message for adjusting Signalling exchange mode to adjacent node D, to inform that node D self will enter power save mode, subsequent node D no longer searches adjacent area the signalings such as signaling and sends to from node A like this.
Embodiment bis-
The present embodiment provides a kind of network energy-saving scheme based on clustering architecture.In energy-conservation node group, have at least one preassigned energy-conservation node as cluster head node, play all energy-conservation node of coordinating in this energy-conservation node group and enter power save mode simultaneously, power back-off node covers the effect of compensation simultaneously.

Step 602, node A sends the request message for asking to enter power save mode to cluster head node C;
Step 603, cluster head node C receives after the request message that node A sends, and judges whether to allow to enter power save mode, if so, enters step 604, otherwise enters step 607;
Here cluster head node C is in the time receiving the request message that node A sends, judge that energy-conservation node in energy-conservation node group is all in normal operating conditions, whether receive the request message that in energy-conservation node group, other all energy-conservation nodes (node A, Node B) are sent except self, if so, allow energy-conservation node group to enter power save mode; Otherwise, do not allow energy-conservation node group to enter power save mode.
Step 604, cluster head node C sends acknowledge message to each other energy-conservation nodes (node A, Node B) in energy-conservation node group and power back-off node S, enters step 605;
Step 605, cluster head node C determines that according to the acknowledge message sending in step 604 energy-conservation node enters the time of power save mode; Other energy-conservation nodes (energy-conservation node A and energy-conservation Node B) in energy-conservation node group determine according to receiving the confirmation message the time that enters power save mode, and enter power save mode on the time that enters power save mode of determining;
Specifically similar according to step 405 and step 406 in acknowledge message mode and the accompanying drawing 4 of definite time that enters power save mode, here no longer describe in detail.
Step 606, power back-off node S receives after the acknowledge message that cluster head node C sends in step 604, determine that energy-conservation node enters the time of power save mode, and strengthen transmitting power on the time of determining, the former overlay area of each node in energy-conservation node group (node A, Node B and node C) is covered to compensation;
Power back-off node S can determine that energy-conservation node enters the time of power save mode by extracting time information from acknowledge message; Or determine the rule of time that enters power save mode according to the time according to receiving the confirmation message of making an appointment, determine the time that enters power save mode.
Step 607, cluster head node C is to sending and wait notice from node A;
Step 608, node A keeps normal operating conditions, wait for receive described cluster head node send acknowledge message time, judgement receives the confirmation message, or occur that self does not meet the situation of the predetermined condition that enters power save mode, if the message of receiving the confirmation enters step 605; If before receiving the confirmation message, there is self not meeting the situation of the predetermined condition that enters power save mode, enter step 609;
Step 609, node A sends the message of cancelling for cancelling described request message that step 602 sends to described cluster head node C;
Step 610, cluster head node C receives cancelling after message that in step 609, node A sends, the request message that delete step 603 receives, cancellation sends acknowledge messages to each other the energy-conservation nodes in described energy-conservation node group.
Preferably, in step 605, before entering power save mode from node A, send the Indication message for adjusting Signalling exchange mode to adjacent node D, to inform that node D self will enter power save mode, subsequent node D no longer searches adjacent area the signalings such as signaling and sends to from node A like this.
