ABSTRACT
As we recall from the general network layers concept, the major tasks of the transport layer are (1) to guarantee reliable transmission of network packets through end-to-end retransmissions or other strategies and (2) to reduce or avoid network congestion due to too heavy traffi c fl ow in the routers or other relay points. TCP is used in the Internet. However, we cannot use TCP in the WSN transport layer design. Th is chapter explains WSN transport layer design requirements and some good protocol examples.
