无线传感器网络（WSN）正在成为许多监测应用的可行工具。这些应用可能具有关键的性质，其中事件的信息从感兴趣区域到某个基站或接收器的传输是关键的，其中不能容忍数据丢失。在另一个方向上，从基站发送到传感器节点的信息（用于控制或管理）也可能对丢失非常敏感。例如，在重新分配传感器节点时，向它们发送程序图像是具有挑战性的。与程序代码相关的单个消息的丢失将使图像无用，并且整个重新任务处理过程将失败。为了解决这个问题，需要一个可靠的传输协议，可以保证数据包的传递，并能满足无线传感器网络的特殊需求和特点。在本文中，我们讨论了无线传感器网络传输层协议的重要性和必要性，并回顾了一些现有的工作。我们还提出在两层无线传感器网络上实现传输层协议，这是一种基于分簇的架构，其中簇头在资源和功能上更强大，可以处理传输层协议的职责，并提供可靠性数据传输
Wireless sensor networks (WSN) are becoming a viable tool for many monitoring applications. These applications may be of critical nature where the transportation of the information of events from the region of interest to some base station or sink is crucial, where the data loss cannot be tolerated. In the other direction, the information (for the purpose of control or management) sent from the base station to the sensor nodes can be very sensitive to loss as well. For example, in re-tasking sensors nodes, sending a program image to them is challenging. A loss of a single message, associated with the program code, would leave the image useless and the whole re-tasking process would fail. To deal with this issue, a reliable transport protocol is needed that can guarantee the delivery of packets and can cater to the special needs and characteristics of WSN. In this paper, we discuss the importance and the need of the transport layer protocol for wireless sensor networks and review some existing work. We also propose to implement the transport layer protocol on two-tiered wireless sensor network, a clustering-based architecture where the cluster-heads, more powerful in resources and features, can deal with the responsibilities of a transport layer protocol, and can provide the reliability in data transmission
