摘要： 为提高无线传感器网络(WSN)的服务质量(QoS),建立了基于多参数传感器微网络(MP_WSMN)数据评价系数μ,并形成通信数据重要性系数ξ。利用传感数据的可靠性μ有效减少了冗余数据占用的带宽;通过系数ξ进行拥塞控制与数据融合,增加了重要数据传输可靠性,有效降低了重要数据的丢包率,提高了WSN的QoS。在基于改进的低功耗自适应集簇分层型(LEACH)路由算法仿真与对古民居火灾探测网络的应用均验证了这一结论。

Abstract: To improve the QoS of Wireless Sensor Network (WSN), this paper set up the sensor data review coefficient μ and the communication data importance coefficient ξ of MP_WSMN. The μ was effective in reducing the redundant data bandwidth. The congestion control and data fusion through ξ effectively increased the reliability of data transmission, and reduced the packet loss rate of the important data. The simulation on the improved LEACH routing algorithm and the application of fire detection network for ancient residences have validated the conclusion.
Key words: mp_wsn, High reliability μ, Importance ξ, QOS, LEACH
