Abstract: Proposes an efficient TIN-based node schedule method for field estimation in wireless sensor networks.Compare to current schedule method,TIN-based node schedule considers spatiality as well as dynamics of field data,through which energy consumption of wireless communication is reduced as well as accuracy of generated field is guaranteed.It is shown by simulation that the TIN-based node schedule can achieve about 10% less communication energy consumption than original one and provide much more scalability.

Key words: wireless sensor networks, field estimation, energy saving, node schedule, TIN

摘要: 针对场监测应用的特点提出了一种基于不规则三角网(TIN)的无线传感器网络节点调度方法。不同于已有的调度方法,此方法综合考虑了感知数据的动态性和空间性,减少了无线传输的电量消耗,同时保证了生成数据场的精度。模拟结果显示,在保证精度要求的前提下,基于TIN的调度方法比传统方法节省10%左右的通信电量消耗,并且具有良好的可扩展性。
