Dynamic ad hoc transport protocol (D-ATP) for Mobile Ad hoc Networks

Redesigning of traditional TCP has been one of the preferred choices among researchers to make it compatible for MANETs. Redesigns of traditional TCP, developed in the past are not more suitable due highly unpredictable environment of MANETs. Therefore, in this paper we have proposed Dynamic Ad Hoc Transport Control Protocol (D-ATP) for MANETs. D-ATP has four main concepts, improved feedback parameter estimation, mobility and life time based path selection, memory aware congestion control, and cooperative reliability enforcement. The highly dynamic networks environment of MANETs has been predicted using the information received from intermediate nodes. D-ATP has been simulated in ns-2. Traditional TCP, TCP-ELFN and ATP have been used for comparative analysis. The result analysis shows that the D-ATP outperforms all the considered protocols in terms of throughput and end-to end delay in realistic environment.
