Need between each node in existing radio sensing network to exchange a large amount of protocol integrated test system data, thus realize between node collaborative.Prior art generally adopts beacon enable mode, be specially: child node associates with father node, when being successfully associated, child node receives the beacon frame that father node sends, and it is synchronous with father node, therefore in the network that the scale of multi-hop is larger, need a large amount of beacon frames to realize the collaborative of node, so that complete transfer of data, cause energy dissipation.And because the transmission of beacon frame is without competition mechanism, so when father node is when transmitting respective beacon frame, have a large amount of beacon frames in a period of time to transmit simultaneously, then can collide each other, once collide, father node just needs to resend beacon frame, adds the number of retransmissions of beacon frame, thus causes the waste of more multi-energy.
When child node sends packet to father node, packet often will through multiple node for data forwarding bag in transmitting procedure, and now, the non-forwarding nodes in child node and forward node communication range also can listen to packet, and this phenomenon is called cross-talk.When there is cross-talk, because non-forwarding nodes also can interception data bag, therefore also result in energy dissipation.Particularly, identical wake/sleep duty ratio up when large quantum nodes has, and when to wake/sleep frequency up be highest frequency in all child nodes, so will produce in packet repeating process and excessively intercept, and will be more serious owing to excessively intercepting the crosstalk problem caused, and cause more multi-energy waste, reduce the validity of energy.
