Abstract: In addition to the optimization of the hardware, the Wireless Sensor Network (WSN) protocol for communication between sensor nodes of varying capabilities (heterogeneous) is a very important factor in determining how long the network will remain operational, and it plays a much more important role than the optimization of the hardware. Researchers and investigators are working to expand the transport layer protocol among several layers of the heterogeneous WSN protocol hierarchy to ensure and prevent congestion issues in WSN and provide assistance with data or application volume reliability, thereby ensuring the Quality of Service (QoS). We try to analyze a transport protocol with a lightweight design, back-to-back dependability, and congestion management transport layer protocol in this research work (CCTLP). By introducing the idea of distributed recollection within the network and fully recovering from packet loss due to congestion by constructively executing congestion identification as well as its rate adaptation method that follows a stochastic control structure, this protocol achieves high data reliability.

TCP NewReno (TCP-NR), TCP Reno (TCP-R), and TCP Westwood are all subjected to an extensive analysis in comparison to the suggested method (TCP-WW). The CCTLP has had network topology confirmed, and the findings demonstrate that it effectively and efficiently reduces congestion. Additionally, it shows 0.3012 Mbps higher throughput, 100 msec average back-to-back (B-2-B) packet latency in data for heterogeneous packet information, 99.89% data packet reliability, and overall energy-efficient actions, such as the lowest per packet communication value in comparison to TCP-NP, TCP-R, and TCP.
