摘要
针对建筑物中无线传感器网络监测技术的特点和实际需求,通过分析现有典型的数据收集协议,提出一种基于区分服务机制的无线传感器网络数据收集算法,兼顾一般数据收集融合处理和紧急数据即刻转发两种服务方式,满足用户对突发事件的监测要求.仿真结果表明,所提算法比现有典型协议有更长的网络寿命和更好的网络可扩充性.
As for the characteristic and requirement of the monitoring technology in the intelligent buildings,a novel differentiated services-based data gathering（DSDG） algorithm is presented based on the research of the existing data collection protocols.It takes into account the general data aggregation and immediate forward for emergency data to satisfy user＇s require for unexpected emergency events.Simulation results show that the DSDG protocol can achieve a longer network life time and scalability than other classic protocols.
