Research And Design On WSN Routing Policy In Transmission Circuitry Monitoring System

WSN is used for data acquisition, real-time monitoring, controlling and other special occasions. Generally it has the characteristics of small size, limited energy, not strong computing capability and so on. Since the applicable requirements of the different situations and function, the routing protocols have focused on the performance.And there is no common version in routing protocols, which requires the developer in accordance with the needs of custom development.Transmission circuitry monitoring system is a typical application in WSN. The sensor nodes deployed on-line rod.Its communication link belongs to the long-chain-type and in the last few jumps it can cause a large number of data congestion, which is called the funnel effect. By reading some of the relevant literature and found that this phenomenon exists in long-chain-type network, with universal representation.In order to solve the funnel effect, this paper Firstly, according to the characteristics of WSN routing protocol on the current common system of comparative analysis done, and then focus on the MIMO technology, particularly its focus on capacity analysis, at last proposed a multi-cluster collaboration routing protocol program that adapted to the transmission circuitry monitoring system, which based on the reasearch of virtual MIMO routiong protocol.In the theoretical study on the basis of the above, application and the OPNET simulation platform compared with the common LEACH, AODV and other related agreements to do the simulation experiments and analysis of various experimental results, the results indicated that the strategy to effectively improve the packet Send the number of lower data latency, significantly improving network performance.Through experimental verification protocol can effectively solve the congestion problems long after the link-type WSN, consider applying to the specific focus on system, based on the characteristics of the system, give full consideration to the practical application of the impact of various factors on the system, proposed the protocol design and implementation of specific programs.
