无线传感器网络的特点，特别是密集部署，有限的处理能力和有限的电源，在传输层提供了独特的设计挑战。传感器节点之间通过无线介质的消息传输是特别昂贵的。必须注意设计一个有效的传输层协议，将可靠的消息传递和拥塞控制与最小的开销和重传相结合。传感器网络是使用低成本、低功耗节点创建的。假设无线传感器具有有限的生命周期，必须小心设计和实现传输层算法，允许最大的网络寿命。在本文中，我们提出了当前和未来的挑战，在传感器网络的传输层的设计。目前的传输层协议进行比较的基础上，他们如何实现可靠的消息传递，拥塞控制和能源效率。
Characteristics of wireless sensor networks, specifically dense deployment, limited processing power, and limited power supply ,provide unique design challenges at the transport layer. Message transmission between sensor nodes over a wireless medium is especially expensive. Care must be taken to design an efficient transport layer protocol that combines reliable message delivery and congestion control with minimal overhead and retransmission. Sensor networks are created using low cost, low power nodes. Wireless sensors are assumed to have a finite lifetime; care must be taken to design and implement transport layer algorithms that allow maximum network lifetime. In this paper we present current and future challenges in the design of transport layers for sensor networks. Current transport layer protocols are compared based on how they implement reliable message delivery, congestion control, and energy efficiency.
