Wireless communications are playing a key role in todays and future communication systems. The advantages of wireless networks in comparison with their wired counterparts include flexible mobility management, faster and cheaper deployment, and ultimately easier maintenance and upgrade procedures. In addition to this, the users are also starting to use the Ad Hoc mode of 802.11 in which multiple wireless hops are used to connect two distant nodes. In this mode, nodes can communicate directly to each other (without a central coordinator) and should relay data to each other in a self-organizing fashion. This configuration is commonly referred to as multihop wireless Ad Hoc networks or simply multihop wireless networks. As the Transmission Control Protocol (TCP) is designed to provide reliable end-to-end delivery of data over unreliable networks (wireless network). In practice, most TCP deployments have been carefully designed in the context of wired networks. Hence to improve TCP performance in wireless mobile adhoc network is ultimately improve the overall performance of communication system. In this paper we have discussed some methods to improve TCP performance in mobile adhoc network. Firstly I-ADTCP method and Secondly Crossed layered based protocol.
