In recent times the uses of wireless devices are fetching ubiquitous and these networks have turn into an increasingly important part of global communication architecture. Information gathering is the problem of sending one packet each from a subset of the nodes to a single sink node in the network. In view of the fact that the vast majority of data applications make use of the TCP/IP protocols, optimizing TCP performance over these networks would have a broad and significant impact on the userperceived data application performance. Most of the wireless networks have fixed infrastructure and the need for mobile wireless networks are growing rapidly, which requires higher data rates. Due to high data rate in wireless networks the TCP performance has a broad and significant impact on data applications. Rapid advances in consumer electronics have led to the anomaly that consumer offthe-shelf gaming hardware and software provide better interactive graphics than military and other specialized systems costing orders of magnitude more. In order to improve the performance of TCP/IP, a UTSAF agent is implemented along with the Transmission Control Protocol (TCP). Performance has been analyzed for the TCP/IP with and without UTSAF agent for the metrics throughput and latency.
