Sensor nodes in wireless sensor networks (WSNs) are capable of sensing the surrounding conditions and transferring data to other nodes in the network. These nodes have limited capacity of in-out data transmission period. So to improve the flow, it becomes necessary to route data efficiently. As the network is self-organized, several security threats are presented to WSNs. In this paper, secure and efficient routing protocol applying Maximum Flow Technique (MFT) is proposed. This technique involves security alongside malicious attacks as well as utilizes the bandwidth efficiently to improve the Quality of Service (QoS). The presented approach is validated by using Network simulator (NS2).

无线传感器网络（WSN）中的传感器节点能够感知周围环境并将数据传输到网络中的其他节点。这些节点的进出数据传输周期的容量有限。因此，为了改善流程，有必要有效地路由数据。由于网络是自组织的，因此向WSN提出了几种安全威胁。本文提出了一种应用最大流技术（MFT）的安全高效的路由协议。该技术不仅涉及恶意攻击，还涉及安全性，并有效地利用带宽来改善服务质量（QoS）。通过使用网络模拟器（NS2）验证了所提出的方法。
