Step 3, estimates dump energy of the node after information switching phase：Transmitter often passes 1bit consumption of information energy： Eelec-te, receiver often receives 1bit consumption of information energy：Eelec-re, and have Eelec-te=Eelec-re；Often transmit 1bit information to lead to Cross the energy that unit distance transmitting terminal amplifier need to be consumed:Eamp, transmitting terminal sends k bits information need to the receiving terminal apart from d The energy of consumption is Eelec-te*k+Eamp*k*d2, receiving terminal receive k bits consumption of information energy be：Eelec-re*k；With m The node of neighbor node needs the energy consumed in information exchanging process to be：
(Eelec-te*k+Eamp*k*d2)*m+(Eelec-re*k)*m；
The dump energy with m neighbor node is after information exchanging process：
Eest1=E1- (Eelec-te*k+Eamp*k*d2)*m-(Eelec-re* k) * m, wherein, E1 is the real-time of the node before information exchange Energy；
Step 4, finds potential death nodes：If node energy meets：It is then potential death nodes, its In,For the average energy consumed in a time period；
Step 5, nodal information is exchanged：Whether each node will include the redundancy information of itself and is potential death nodes Information be broadcast to all of neighbor node；
Step 6, non-potential death nodes estimate the position that whether can move to potential death nodes；
Estimated information exchanges the energy for consuming：To enter row information exchange, this process consumed energy before all removable node motions For：
(Eelec-te*k+Eamp*k*d2)*L+(Eelec-re* k) * L, L is the number of the node exchanged into row information, and k is information Bit, d are the distance of information transmission；
If node motion, node dump energy after movement is estimated：
Eest2=E2- (Eelec-te*k+Eamp*k*d2)*L-(Eelec-re*k)*L-Emove* h, wherein, h is to move to target location Distance, E2 is the real-time power of the node before movement；
Whether decision node has mobile energy：It is required that mobile node at least works x time period after new position on earth, if saving Point energy meets：Then this node has the energy for moving to target location, otherwise, not with this energy Power, wherein, x is threshold value set in advance；
Step 7, determines mobile node：
Optimal node is selected in all moveable nodes according to following rule：
If there is absolute redundant node in removable node, judged according to target range, move the absolute of target range minimum Redundant node；If the target range that there are multiple absolute redundant nodes is equal and is minimum, further according to dump energy Eest2 Size judge, the node for selecting dump energy maximum；
If there was only relative redundancy node in removable node, selected according to the displacement of relative redundancy node, phase To the maximum movable distance that the distance that redundant node is moved is relative redundancy node, maximum movable distance is referred to not to be affected The moveable ultimate range of node under conditions of overlay area, according to maximum movable distance relative redundancy node motion is determined Target location；Compare the maximum movable distance of relative redundancy node, the minimum relative redundancy section of mobile maximum movable distance Point, if the maximum movable distance that there are multiple relative redundancy nodes is equal and is minimum, further according to dump energy Eest2 Size judge, the node for selecting dump energy maximum,
Step 8, to remaining absolute redundant node sleep scheduling mechanism is adopted：After node motion to target location, will be definitely superfluous Remaining node state changes into sleep.
