Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is this hair
Bright some embodiments for those of ordinary skill in the art without creative efforts, can be with root
Other attached drawings are obtained according to these attached drawings.
Fig. 1 is the broadcast transmission sequential schematic of each broadcast transmission period interior nodes of embodiment 1；
Fig. 2 is the broadcast transmission sequential schematic of each broadcast transmission period interior nodes group of embodiment 2.
Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments；It should be noted that in the absence of conflict, in the application
Embodiment and embodiment in feature can be combined with each other.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Embodiment 1
Either battery saving mode node or general mode node the broadcast transmission mode that all uses variable period in the present invention,
The sleep cycle that battery saving mode node is arranged is P broadcast transmission chance, and the multiple that the node total number N that network is arranged is P
(if actual node number is not the multiple of P, can plan that several dummy nodes make node total number be the multiple of P), N number of net
The number of network node is successively denoted as 0,1 ..., N-1.
A broadcast transmission period is constituted per N number of broadcast transmission chance, broadcast transmission period number is successively denoted as 0,1,
2 ..., all nodes occupy broadcast transmission chance in turn in one cycle, network node in j-th of broadcast transmission period
Broadcast transmission sequence are as follows: i-th of broadcast transmission chance is mod (i+Sequence by numberingmod(j,N), N) node occupy,
In, j=0,1,2 ..., i=0,1 ..., N-1, Sequence are the sequence that length is N, SequencekFor Sequence's
Sequential element, k=0,1 ..., N-1, sequential element are made of 0,1 ..., N-1 random rearrangement, that is to say, that each sequential element
A numerical value in 0,1 ..., N-1, size order can be it is random, as long as different.
Present embodiment assumes that sharing N=8 node in self-organizing network, therefore every 8 broadcast transmission chances constitute one
Broadcast transmission period, the sleep cycle of battery saving mode node are P=4 broadcast transmission chance, i.e., every 4 send opportunity wake up one
It is secondary, it can send with listening broadcast information, sequential element Sequence in Sequence sequencek=k.Then each broadcast transmission
Period interior nodes broadcast transmission sequence as shown in Figure 1, specifically:
In 1, the 0th broadcast transmission period, i-th of broadcast transmission chance is occupied by node mod (i+0, N), i=0,
1,...,7；
In 2, the 1st broadcast transmission period, i-th of broadcast transmission chance is occupied by node mod (i+1, N)；
In 3, the 2nd broadcast transmission period, i-th of broadcast transmission chance is occupied by node mod (i+2, N)；
4, and so on, in j-th of broadcast transmission period, i-th of broadcast transmission chance by node mod (i+mod (j, N),
N it) occupies.
From figure 1 it appears that the broadcast of this node can be transmitted in a broadcast cycle in general mode node, and monitor
To the broadcast of all neighbor nodes.Every 4 send opportunity (TO, transmit opportunity) of battery saving mode node wake up one
Secondary, then within a broadcast transmission period, which can be sent or be monitored in 2 send opportunity, be broadcasted by 4
Period can complete primary complete broadcast receiving and transmitting.By taking battery saving mode node Node2 as an example, it is assumed that it is in the 1st transmitter
It can wake up with the 5th send opportunity, then Node2 can listen to Node0 and Node4 in broadcast cycle 0, in broadcast cycle 1
Node1 and Node5 can be listened to, own broadcast can be transmitted in broadcast cycle 2 and listens to Node6, it can in broadcast cycle 3
Listen to Node3 and Node7.Exactly because can be seen that SequencekSequential element in sequence is different, so
The node that Node2 is listened in the identical send opportunity in the different broadcast transmission periods is not overlapped, by 4 broadcast weeks
After phase, Node2 can be collected into the broadcast message of all neighbor nodes, and necessarily contain Node2 in this 4 broadcast cycles
A broadcast transmission chance.
Embodiment 2
When the number of nodes in network is more, node can be grouped, each node group shares a broadcast transmission
Chance.Present embodiment assumes that sharing 32 nodes in self-organizing network, every 4 nodes constitute a network node group, share 8
Node group, the node in each network node group share a broadcast transmission chance using time division way.
For the present embodiment by the way of same as Example 1, the sleep cycle of setting battery saving mode node is P=4 wide
Send opportunity is broadcast, every 8 broadcast transmission chances constitute a broadcast transmission period, and broadcast transmission period number is successively denoted as 0,1,
2 ..., all node groups occupy broadcast transmission chance in turn in one cycle, different node groups are using same as Example 1
Sequence carry out broadcast transmission.Each broadcast transmission period interior nodes group broadcast transmission sequence as shown in fig. 2, it can be seen that
Similarly with embodiment 1, the broadcast of this node can be transmitted in a broadcast cycle in general mode node, and listens to all neighbours
The broadcast of node；Every 4 send opportunity of battery saving mode node are waken up once, transmission and listening broadcast information, four broadcast weeks
Primary complete broadcast receiving and transmitting is completed after phase.
