摘　　要：针对当前无线传感网络传输效率不高的问题,提出了一种无线传感网络传输优化策略。该策略基于跨层访问机制,利用网络各层之间虚拟的信息交互管道,实现层间信息的直接交互。引入自律计算思想和反馈机制,利用跨层访问获取网络各层状况,实现网络传输的自适应调节,达到提高网络传输效率的目的。仿真实验结果表明:本文提出的网络传输优化策略与传统的分层访问机制相比,在提高传输效率、均衡网络能耗以及提升网络整体性能等方面具有较好的效果。To solve the problem that the wireless sensor networks( WSNs) had lower transmission efficiency currently,a WSNs transmission optimization strategy based on cross-layer access was proposed. By cross-layer access mechanism,virtual information interaction pipeline was used among each layer to realize information interaction between the layers directly. Moreover,the autonomic computing thought and feedback mechanism were introduced,and cross-layer access was used to acquire network layers status. The adaptive adjustment of network transmission was realized,and the efficiency of network transmission was improved. The simulation results show that the network transmission optimization strategy has a better performance in terms of enhancing transmission efficiency,balancing energy consumption of network and improving network performance than traditional layered-access mechanism.
