Research on Reliable Information Fusion Model in Wireless Sensor Network

随着通信、传感器技术的日益完善与成熟,微型无线传感器逐渐拥有了良好的计算、感知及通信能力。应用无线传感器,可精准捕捉并收集限定网络区域内的各种信息,供有需要的用户使用。但是受传感器节点能量有限,当能量损耗殆尽时,无线传感器将会停止工作。为了延长网络生命期,让传感器节点能量得到充分利用,可以应用信息融合技术对数据进行处理,减少数据量,提升准确性,延长无线传感器的使用时长。从实际情况出发,提出了利用基于层次结构的可靠信息融合技术构建模型的构想,并对其进行了仿真测试,证明其可以达到预期效果。

With the improvement and maturity of communication and sensor technology,miniature wireless sensors gradually have good calculation,perception and communication capabilities.The application of wireless sensors can accurately capture and collect various information within a limited network area for users in need.However,the energy of the sensor node is limited.When the energy is exhausted,the wireless sensor will stop working.In order to prolong the life of the network and make full use of the energy of sensor nodes,information fusion technology can be used to process data,reduce the amount of data,improve accuracy,and extend the use time of wireless sensors.Starting from the actual situation,the idea of using reliable information fusion technology based on hierarchical structure is proposed to build a model,and simulation tests are carried out to prove that it can achieve the expected effect.
