无线传感器网络中可靠的数据协作传输机制

Reliable cooperative data transmission mechanism for wireless sensor networks

对基于协作通信的数据传输问题进行了研究,设计了一种适应于无线传感器网络的RBC网络编码方法,提出了一种数据协作传输策略,分析了端到端的中断概率,评估了中继选择过程的有效性,开发了一种ACK-less的基于协作策略的数据传输方法,理论分析和仿真实验表明,所提出的协作数据传输机制,能够更加有效地使用网络资源。

The efficient data transmission problem through cooperative communication was studied,a network coding was designed with random binning implements for wireless sensor networks,a cooperative data transmission scheme combined with the network coding was proposed,analyzed the end-to-end outage probability was analyzed.the usefulness of relaying was evaluated,and an ACK-less data transmission method based on the cooperative mechanism was developed.The theoretical analysis and experimental simulations show that they allowing for a more efficient use of resources.
