The TCP networks have been the only communication for wired media that followed IEEE 802.3 networks. This paper attempts to provide a comprehensive overview of this Link Layer approach, i.e., Snoop protocol that improving throughput of TCP in wireless networks. It explains the role of Snoop protocol that overcomes the limitations of TCP protocols in wireless media. The authors investigated the application of this protocol in wireless networks and observed that a single hop in the wireless network experienced large variations in round trip time in a very short period. Without changes to the Snoop protocol to accommodate these dramatic RTT variations, Snoop was performing badly compared with regular TCP even when there were no packet losses or errors.
