It is for data arrive destination node with optimal path through communication subnet service to be provided that route technology mainly acts on.Routing Protocol is an indispensable ingredient in the MANET architecture; It mainly acts on is to find and safeguard route to mainly contain the following aspects: monitor network changes of topology structure, exchanging routing information; Confirm the position of destination node, produce, safeguard and the cancellation route.In order to reach low-cost, low-power consumption, the design object that reliability is high, this patent adopts the routing algorithm of the coalition of following two kinds of algorithms as self.
1) AODV:Ad-Hoc On-Demand Distance Vector (distance vector route as required)
2) Cluster-Tree algorithm (tree network structure route)
In the ZigBee network, node can use the Cluster-Tree algorithm to select the path according to the filiation of network tree structure.It is the descendent node that each node all can attempt the packets of information of receiving is transmitted to oneself; If find that through calculating destination address is not the descendent node of oneself; Then this packet is transmitted to the father node of self upper level; Carry out similar judgment processing by father node, up to finding destination node.The characteristics of Cluster-Tree algorithm be to make between node with routing function through with separately father node between communicate by letter and still can send packet and divide into groups with control, but that its shortcoming is an efficient is not high.In order to raise the efficiency, the node that allows among the ZigBee to have routing function uses the AODV algorithm to go to find route, lets the node with routing function can directly send information to other nodes in its communication range not according to filiation.

(3) each monitoring infusion node adopts intermittently sleep mode, and is every at a distance from several seconds calculating transfusion bottle/bag and contained liquid medicine component thereof, and this information is passed to partner node, finally is sent to center machine on duty, shown by center machine on duty;
(4) center machine on duty is with the remaining weight and the threshold value contrast of each transfusion point, and transfusion point residue transfusion time is somebody's turn to do in prediction, and the monitoring infusion node that closes to an end is sent warning message.
10. the transfusion method of servicing based on topology wireless networks is characterized in that, may further comprise the steps:
(1) center machine on duty adopts fixed power source, powers on and carries out initialization, starts application program; Monitoring infusion point adopts battery, the back initialization that powers on, and, adopt optimized Algorithm to realize the correspondence setting between dynamic network node through the detecting wireless signal intensity, the WiFi communication module is carried out WiFi with the strongest unit of signal and is communicated by letter;
(2) different by the doctor according to patient's medication, for each transfusion terminal alarm threshold is set at center machine end on duty;
(3) each monitoring infusion node adopts intermittently sleep mode, and is every at a distance from several seconds calculating transfusion bottle/bag and contained liquid medicine component thereof, and this information is passed to partner node, finally is sent to center machine on duty, shown by center machine on duty;
(4) center machine on duty is with the remaining weight and the threshold value contrast of each transfusion point, and transfusion point residue transfusion time is somebody's turn to do in prediction, and the monitoring infusion node that closes to an end is sent warning message.
