Presently accelerating the energy-conservation in Mobile Ad-Hoc Networks (MANETs) has been a herculean task. The LAR-1 (Location-Aided Routing-1) position-based routing scheme in network has recently invoked interest in the domain of energy-conservation as it extends the network lifetime of the networks. This paper has especially studied and investigated the N-LAR-1 (New-LAR-1) methodology given via TCP packets for reliability and security in Ad-Hoc network. TCP with ACK signals is frequently used in the field of data streaming or communication than UDP. Prominent results have been accomplished through same routing approach by utilizing the sleep mode condition of mobile nodes in Ad-Hoc Network. Thorough analysis of performance metrics using the above mentioned approach have been reported with TCP-Reno, TCP-New Reno, TCP-Vegas and TCP-SACK. An exemplary result from TCP-Vegas and TCP-New Reno is being achieved in this paper.
