Wireless sensor networks (WSN’s) consist of spatially distributed sensor nodes
that are related devoid of any wiring. Here, sensor nodes sense data from their
environments and use communication units for communicating the sensed data over
wireless channels. Huge variety of applications are supported in wireless sensor
networks. The wireless sensor networks are used in environmental monitoring, military
reconnaissance, emergency rescue operations etc.. There are many challenges available
in the wireless sensor network. They are Quality of Service(QoS), fault tolerance,
scalability and maintainability. Here, we choose the Quality of Service to measure the
performance of Transmission Control Protocol (TCP) flows.Throughput are present in
the parameter Quality of Service. There are two algorithms are used to measure the
throughput. The first algorithm is TCP aware Backpressure and another one is Ad-hoc
On Demand Distance Vector (AODV). Distinguish these two algorithms which one is
giving a better performance of TCP flows.
