近年来，无线传感器网络以其独特的特性和广泛的应用受到了广泛的关注。特别是在军事网络中，所有的传感器节点都是随机和密集部署的。我们如何优化部署节点的数量（传感器节点和接收器）与QoS保证（最小的端到端延迟和数据包丢失）？本文利用M/M/1排队模型，提出了一种非信标模式802.15.4传感器网络的部署优化模型。仿真结果表明，该模型是一种很有前途的传感器网络部署方法。
Wireless sensor networks (WSNs) have attracted much attention in recent years for their unique characteristics and wide use in many different applications. Especially, in military networks, all sensor motes are deployed randomly and densely. How can we optimize the number of deployed nodes (sensor node and sink) with a QoS guarantee (minimal end-to-end delay and packet drop)? In this paper, using the M/M/1 queuing model we propose a deployment optimization model for non-beacon-mode 802.15.4 sensor networks. The simulation results show that the proposed model is a promising approach for deploying the sensor network.
