摘要
为了改善无线传感器网络井下应用的网络性能,减少sink节点的拥塞,保证井下无线通信的可靠性,采用分支树理论改进S-MAC协议,设计了一种基于多重分支树的跨层协议,并结合井下的应用环境对协议进行仿真,仿真结果表明,改进的协议在减少拥塞、提高传输速率等方面具有较好的特性。
In order to improve the network performances of the wireless sensor network applied in the underground mine, to reduce the congestion at the sink nodes and to ensure the reliability of the underground wreless communication, the multiple - tree theory was applied to improve the S-MAC protocol. A cross layer protocol was designed based on the multiple - tree protocol. To simulate the protocol with the underground mine application environment. The simulation results showed the improved protocol would have better features to reduce thecongestion and improve the transmission speed.
