Design Of The Agriculture Environmental Monitoring System Based On Multi Hop Ad-hoc Network Technology

With the deepening of electronic research technologies and the improvement and evolution of computer networks and wireless communication agricultural production production also usher in a new era of modernization and scientification.Based on the analysis of the advantages and disadvantages of the traditional agricultural environment monitoring system,this paper proposes an agricultural environment monitoring system based on multi-hop ad-hoc network technology.This technology is based on wireless communication technology,which is used to realize the collection and transmission of information among equipments' nodes.And solving the disadvantages of traditional agricultural monitoring system,such as a large number of artificial investment,high cost,difficult maintenance and the hard of networking.Based on the Multi-hop ad-hoc network technology,this paper uses the CC2530 chip to complete the design of agricultural monitoring system's equipment nodes about the software and hardware.The nodes of hardware completed by the CC2530 chip include coordinator node,and equipment nodes.Among them the coordinator node completes the establishment of agricultural monitoring system's ad-hoc network and the correspondence management work with personal computer(PC),conveys the orders of monitoring and receives the information returned by the node;the equipment nodes apply to join in the network established by coordinator node and complete the work of collection of parameters;build system test platform for verifying experiment analysis to confirm the feasibility of system implementation.While completing the monitoring function of agricultural system,this paper also studies on the problem of network node localization.The disadvantages of traditional DV-hop positioning technology are analyzed in detail,The traditional DV-hop localization algorithm modified by RSSI principle and theoretically verified by MATLAB simulation software put forwarded.Compared with traditional agricultural environmental monitoring equipment,the monitoring system designed in this paper basically achieved the collection and transmission of some agricultural environmental parameters.And this system can ensure good connectivity in the agricultural monitoring area through a multihop Ad-hoc network technology,and can achieve intelligent and low-power design of the agricultural monitoring system.
