无线传感器网络中双缓存节点模型的研究

wireless sensor network is a network system consisting of a large number of sensor nodes, which can collect and transmit large-scale data streams. In this paper, we propose a dual cache node model, where each node has two queues to store packets, one for buffer and one for storage. this model can improve the robustness and flexibility of the network, but it also increases the complexity and latency of the network. In this paper, we model and simulate experiments on this model to reveal the quantitative relationship between packet loss rate and transmission delay, and design a data arrival and transmission mechanism based on dynamic adjustment, aiming to reduce the transmission delay of nodes as much as possible while ensuring that the packet loss rate is within an acceptable range.
