Research On Topology Control For Wireless Sensor Networks

At present the sensor network technology already took future will liveto thehumanity produces the profound influence heads of ten bigemerging technologies,will have the huge application value. The analysis topology control algorithm andthe research and sensor network universal existence limited question and so on doescomputation ability, limited memory property, limited wireless traffic capacity andlimited power source supply ability, how gain as far as possible much, as far aspossible the effective sensation object characteristic information under the suchlimited resources environment, and transmits the user pitch point to carry onprocessing, is key question which at present studies, these questions all may sum upas the sensor network analysis topology control method question. This articleconducts the research in view of the sensor network analysis topology control incertain questions, the main research work manifests in following several aspects:First, existing winds the principle of design and the structure existencelimitation in view of the wireless sensor network, and is suitable the networkagreement by the existing network architecture to conduct the research, proposed themix tree wireless sensor network topology. It has realized the breadth distributionlarge-scale network is omerism skeleton. It has solved high density multi- types pitchpoint wireless sensor question and so on network equipment diversification, datadiversification, cover scope diversification.Second, in view of the network power control and the muti-level controlmethod existence mechanical type work way, proposed in the net the pitch pointcoordination inspiration mechanism analysis topology control research technique,and increased the belt information comparison, the time quota method and increasesthe heavy route way in the network the pitch point coordination inspirationmechanism, reduced the power dissipation, changed the pitch point phase transitionthe time limit mechanism. It solved in the sensor network the pitch point to bepossible the auto-adaptive work way question. Third, aims at the network life time to lengthen with the essential pitch pointlocalization engineering research, proposed lengthens the network life time a bunchof choice and the data retransmits the method. Has realized the network architectureoptimization, improved the data transmission quality, and increased the networkpower use factor. It reduced the nonessential way choice, in some kinds of degreereduced the redundancy dispatch which in the network exists.Fourth, in view of the network auto-adapted analysis topology control methodfundamental research, proposed the belt pre- request information consultationanalysis topology control thought, proposed based on lengthens the life time andimproves the data quality the backup type analysis topology control method;Proposes the smallest lifetime smallest bit rate smallest energy consumption networkanalysis 3M topology control algorithm. Realized in the auto-adapted analysistopology control method to enhance the network life time, to reduce the power loss,enhances function and so on intelligence transmission integrity.Fifth, has completed the wireless sensor network in the concrete dam conditioninformation long-distance monitor system application design, including the networktopology design, retransmits chooses in advance, aspect the and so on analysistopology control research and the analysis. It realized the isomerism form to have theauto-adapted wireless sensor network long-distance information monitor.In brief, this article according to took the complex network the sensor network,enhances the network the surplus resources use, enhances the network the life time isthe principle, mainly concentrates to in the analysis topology control certainquestions in the sensor network structure, the data distribution, aspect and so onnetwork mechanism coordination deployment plan, the findings indicated has theauto-adapted type the network topology to have the more superior disseminationefficiency and the lower dissemination price, and can greatly enhance in the networkthe energy use factor.The entire research revolved the wireless sensor network analysis topology thestructure and the control method carries on studies and designs and has yielded thecertain result, finally completed the wireless sensor network in the concrete dam condition information long-distance monitor system application design, the effecthas been good.
