Abstract: Due to the characteristics of the rural water supply network,such as long data networking distance,a large number of monitoring points,and poor operating conditions of field equipment,it is difficult for the traditional networking methods to comprehensively take into account various requirements（i.e.,economics,reliability,and implementation difficulties）and problems（i.e. peripheral power supply support and coordination of the installation position）. A self-organizing wireless network-Ad Hoc,on the other hand,is an economical and efficient choice,especially in mountainous rural areas,pasture areas,and alpine regions. However,there are many limitations to the existing universal self-organizing network and supporting equipment,which makes it difficult to support the combined power supply of solar energy and battery, facilitate on-site installation and support low-end chips. In particular,long-distance communication through pipe networks is faced with practical problems,including the need to purchase base station relay equipment. Based on the central link planning method,this paper proposed a proprietary ad hoc wireless communication protocol for rural water supply networks,analyzed from the aspects of data packet definition,message forwarding mechanism,node relationship acquisition method,and central unified routing management strategy. Compared with the traditional methods,the hardware equipment based on this protocol reduce power consumption and allow the power supply of low-end chips and small solar panels,thereby enabling quick on-site installation without relying on peripheral power supplies. At the same time,this protocol can realize stable and efficient data networking and transmission without intermediate base stations.
