| Middle and High Rate Wireless Sensor Networks(MHR-WSN), developed from traditional wireless sensor network(WSN), needs into the processing of multimedia, video, audio, file transfer and other diversified data. MHR-WSN has specificity a huge amount of data and transmission rate. The node energy is seriously constrained for high rate sensor network. The complexity of the network links makes wireless signal suffer interference during transmission vulnerable.QoS guarantee, energy efficient and reliable transmission has become an important index to measure the performance of the network. The network can combine with sensing technology, distributed information processing, Internet, integration of IOT technology. MHR-WSN has huge research value and wide application prospect on industry and agriculture, bio-medical, environmental monitoring, remote control of hazardous area and other fields. Therefore, study of low interference, high speed wireless sensor network energy efficiency has important significance.Wireless Sensor Network can organize itsel wireless network for the transmission of information. Homogeneous or heterogeneous susceptible to interference in the network transmission process,the transmission performance of WSN have been seriously affected for the deployment of the wireless sensor network requirements,space energy and bandwidth constraints. In order to meet the performance requirements of WSN, it becomes especially important to research to reduce the nodes of the wireless signal interference between the complex topology model and Routing Transfer Protocol. The interference problem existing, it will reduce the efficiency of the communication of the wireless sensor network, increase the network communication delay, can not receive the data correctly, cause originator retransmission, and increase the energy consumption of the network, unable to guarantee QoS.This artical concentrates interference of MHR-WSN among nodes.To study on the interference of topology optimization control technology and energy optimization routing protocol, the main responsibilities as follows: (1)The composition and characteristics of the wireless sensor network interference are focused, and the interference modeland the routing protocols of interference are introduced.(2) In-depth study of existing wireless sensor interference optimization topology control algorithm and taking into account the interference topology control mechanisms of interference in the WSN node,considering the influence of interference on topology control design for many wireless sensor networks, a distributed hybrid topology optimization control algorithm for interference aware is proposed.Firstly, according to the relationship between communication and the transmission distance and the interference of randomly distributed sensor nodes,a farther away node at low load is connected by adjacent nodes at high load.Then, the topology is generated by first computing the Gabriel graph from the Unit Disk Graph at maximum transmitter power and then computing the Yao graph on the reduced topology to produce the final topology. Simulation results are presented demonstrating the higher efficiency and lower interference of this new technique as compared to other approaches to topology control, guarantee QoS.(3) Based on the physical transmission characteristics of the wireless link, it can guarantee successful to transmit and receive data, an energy efficient routing algorithm of interference adaptive for WSN is proposed. The algorithm finds the minimum energy link by improving the interfering node energy or switching channel outside interference zone,which ensure that the total energy of the entire network path minimum or near-minimum. In order to prevent disturbed node energy improving to demise excessively.an energy confidence level a is introducted. The simulation experiments show that the algorithm can balance the energy consumption of the whole network and prolong survival time of WSN to ensure the node transmission power and connectivity. |
