To find out the dependency of Transport layer on MAC/PHY layer, the authors have extensively tested various transport protocols using IEEE 802.11, IEEE 802.15.4 MAC/PHY protocols for WSN. For IEEE802.11 and IEEE802.15.4 with RTS/CTS ON the TCP variants has shown >80% packet delivery ratio and 5-20% packet loss, while for UDP it is around >63% and 19.54-35.18% respectively. On average 1-3% additional energy is consumed for packet retransmissions in IEEE 802.11 with RTS/CTS OFF whereas significant energy efficiency is observed in IEEE802.15.4 case. For IEEE 802.11 with RTS/CTS ON high throughput, low packet drop rate and increased E-2-E delay is observed, while for IEEE 802.15.4 improved power efficiency and jitter behavior is observed. This has led the foundation for the future development of the cross-layered energy efficient transport protocol for WSN.

Other than hardware optimization, the communication protocols for heterogeneous Wireless Sensor Network (WSN) are currently playing an important role for achieving the longevity of the network. Among other layers of heterogeneous WSN communication protocol stack, researchers are putting efforts in developing transport layer protocols in order to avoid congestion in WSN and provide data or application level reliability support thereby ensuring the QoS objectives of the heterogeneous WSN application. In this paper we have envisaged a light weight transport protocol design, End-to-End Reliable and Congestion Aware Transport Layer Protocol (ERCTP), which achieves high data reliability by the introduction of distributed memory concept within network and minimum packet drop due to congestion by the effective implementation of congestion detection and rate adjustment scheme that uses stochastic control framework. The proposed scheme is evaluated extensively against the TCP-Westwo...
