An Efficient Ad Hoc Transport Protocol (ATP) for MANETs

Mobile ad hoc networks (MANETs) are very intricate accumulation of wireless mobile nodes that can be liberatingly self-organized into dynamically ephemeral network topologies. Many researchers spent a considerable duration on amending the performance of reliable transport protocol i.e. TCP for MANETs. TCP surmises that any losses in the network are due to congestion and responds with congestion control mechanism in all situations which results in poor performance. Ad hoc transport protocolATP is an incipient protocol that fixates on impotency of TCP for MANETs. In this paper, we are evaluating the TCP performance under MANET scenario and represents the ineptly illfittedness of TCP for MANETs with increasing no. of mobile nodes it responds in decreasing throughput. And discuss the properties and mechanism of ATP. The experiment is done using NS-2 simulation tool. Based on theoretical analysis and experimental result ATP is well suited for MANETs.
