Wireless Sensor Networks (WSNs) provide a powerful means to collect information on a wide variety of natural phenomena. WSNs typically consist of a cluster of densely deployed nodes communicating with a sink node which, in turn, communicates with the outside world. WSNs are constrained by low power, dense deployment, and limited processing power and memory. This paper presents a survey on transport protocols for Wireless Sensor Networks (WSNs). In this paper, the authors present current and future challenges in the design of transport layer protocols for sensor networks. Current transport layer protocols are compared based on how they implement reliable message delivery, congestion control, and energy efficiency.
