In this article, we present a survey of Wireless Sensor Networks (WSNs) existing Transport Protocols. We have evaluated the design concepts of different protocols based on congestion control, reliability support and source traffic priority support. Then we draw the concluding remarks, while highlighting up-and-coming research challenges for WSN transport protocols, which should be addressed further...
Achieving QoS objective in Wireless Sensor Network (WSN) that deals with multimedia information is of paramount importance in the WSN research community. From the application point of view, meeting application specific QoS constraints is equally important as designing energy efficient embedded circuitry for WSN nodes. Among various WSN communication protocol stack, the transport layer functionality...
Designing a reliable transport protocol is a new challenging area in wireless sensor networks (WSNs). Traditional transport layer protocols (such as TCP and UDP) canpsilat directly be applied to the WSNs. Generally transport layer is responsible for congestion control and reliable packet delivery. Congestion is an essential problem in WSNs. It not only wastes the scarce energy due to a large number...
Re-tasking and remote programming of sensor networks is an essential functionality to make these networks practical and effective. As the availability of more capable sensor nodes increases and new functional implementations continue to be proposed, these large collections of wireless nodes will need the ability to update and upgrade the software packages they are running. Standard flooding mechanisms...
