无线传感器网络节能接入协议算法研究

Wireless Sensor Network Saving Access Protocol Algorithm

无线传感网络依靠许多移动或者静止的多传感器,并以一定的构成方式进行布局,目前通常分为自组织和多跳两种网络组成形式。针对无线多传感器的定位算法已经提出了很多,但是大部分都是基于二维平面的网络环境,而在实际应用中,三维空间的网络节点分布更适合实际部署环境,提出了一种三维空间传感器节点的虚拟阵列被动声定位模型。在方向性传输环境下,针对S-MAC协议和T-MAC协议良好的低能耗性能,提出了一种基于T-MAC协议的数据双向传输的BA-MAC协议。通过仿真结果可以看出,BA-MAC协议在能量节省和网络系统性能上都优于S-MAC协议和T-MAC协议。

Wireless sensor networks rely on many mobile or stationary sensor, and layout in a certain way of composing, there is usually divided into self-organizing multi-hop mode network of forms. Localization algorithm for wireless multi-sensors has pro- posed a lot, but most of them are based on a two-dimensional plane of the network environment, but in practical application, the three-dimensional spatial distribution of the network node is more suitable for the actual deployment environment, a three-dimen- sional sensor virtual array passive localization model is presented. In directional transmission environment for S-MAC protocol and T-MAC protocol excellent low-power performance, a two-way data transmission T-MAC protocol is proposed based on the BA-MAC protocol. The simulation results show that, BA-MAC protocol on energy savings and network performance are better than S-MAC protocol and T-MAC protocol.
