Design A Chain Style WSNs Based On ZigBee

With the rapid development of Internet of Things in recent years, the basic supporting technology Wireless Sensor Networks has been getting mature. Nowadays, the study of WSNs mainly focus on the design of routing protocol. Due to the sensor node calculation ability, storage ability, communication ability and carrying energy is limited, each node can only obtain the local network topology information, its running on the network protocol is not too much complicated. In addition, because of the dynamic change of the topology, the network resources are also changing, put forward higher requirements on Wireless Sensor Networks.Due to the nature of the wireless sensor node itself, the research of wireless sensor network can not like a traditional computer network system researched by simulation combining physical measurement to measure the performance of an algorithm, or a protocol. Wireless sensor networks(WSNs) usually use the computer simulation for network performance evaluation, and through the analysis of the simulation structure to guide the maintenance and deployment of sensor nodes.The main work and results are as follows:(1)Based on the theory of common several kinds of wireless sensor network routing protocol a large number of literature reading, the research status quo on system analysis, to explore the application characteristics of different routing protocols. And analyzed the different application scenarios should have the characteristics of wireless sensor network(WSN).(2) With emphasis on the chain of wireless sensor network application. Study the characteristics of linear wireless sensor itself, summarizes the chain of wireless sensor network routing protocol should have characteristics.(3) According to the linear characteristics of the wireless sensor network routing protocol should possess, design based on the beacon frame of on-demand routing algorithm and the active routing algorithm based on delay wave, and the simulation model is set up respectively, using OMNET++ software simulation experiment, according to the data, analysis the performance of this two kinds of routing protocols, put forward the theoretical guidance for the application of the relevant scenario. Fusion of these two kinds of algorithms, this paper puts forward a kind of stable and flexible routing protocol.(4)With CC2530 platform that made by TI, development entity model based on the proposed routing protocol of wireless sensor network, and applied to the industrial enterprise data monitoring and collection.
