Development Of Fine Corp Monitoring System Based On Wireless Sensor Networks And Research On Routing Algorithm

Wireless Sensor Networks(WSN) is a new type of networks. It is the integration of sensors, embedded computing, networking, and wireless communications technology. The nodes of WSN can collaboratively monitor, perceive and collect all kinds of information from Objective world, then deal with, and send them back to the users who need them.Because wsn has brought great facility to our lives and production,this technology has caught great attention from many countries and orgnizations.It is a new hotspot in the field of computer science and has a very broad application prospects.Nodes of Wireless Sensor Networks have such features:huge number,small volume, Limited energy in one single node, difficulty in recharging the node.Once the energy of a node is Exhausted, this node will be out of work. When a great number of nodes are out of work,the whole network will break down. Because to change the manner of power supply and to lower power consumption is restricted to the nodes’ cost, size, and other factors,so the research of sensor network routing protocols and algorithms to conserve energy, and to extend the lifetime of sensor network is of great significance.On the background of practical application of JiFa Biological Environment Monitoring, based on the hardware of WSN nodes from American Crossbow Corporation,we have developed the JiFa Greenhouse Environment Monitoring System.In this article,we will introduce requirement analysis,function design,system architecture,database design, business logic, demonstration of the key system function. Aimed at this specific application background,we Propose the TRA algorithm, The simulation results in NS2platform show that this TRA algorithm effectively enhanced the Utilization node energy and the balance of nodes load and greatly extends the Life cycle of the network.
