Water resources consumption of city green belt lawn irrigation is increasing

it has become necessary choice for precision irrigation according to plants’need.Describe application of wireless sensor network（WSNs）in precision irrigation of city greenbelt lawn from the point of view of engineering application and related problems.Analyze link communication quality of WSNs by packet loss rate

received signal strength indicator（RSSI）

etc

which provide empirical datas supports for node deployment and routing protocol design.Improve the minimum hop count routing protocol to suit engineering environment

and simulation experiment and actual operation verify that its effectiveness on energy consumption of network reducing.
