TCP- Transmission Control protocol is a connection oriented and reliable process-to-process communication on the transport layer of tcp/ip model. TCP guarantees with the end-to-end flow control, error control and congestion control. In the past, tcp was brought to work with the bulky networks where the cause of losses is specially the network congestion. TCP was introduced to work with the wired networks where the cause of losses is mainly the network congestion. In recent years, wireless networking is becoming more and more popular. Wireless Sensor Networks consists of hundreds and thousands of micro sensor nodes that monitor a remote environment by data aggregation from individual nodes and transmitting this data to the base station for further processing and inference. The energy of the battery operated nodes is the most vulnerable resource of the WSN, which is depleted at a high rate when information is transmitted, because transmission energy is dependent on the distance of transmission. In a clustering approach, the Cluster Head node looses a significant amount of energy during transmission to base station. So the selection of Cluster Head is very critical. An effective selection protocol should choose Cluster Heads based on the geographical location of node and its residual energy
