Mobile Ad hoc Networks (MANET) are a collection of mobiles and smart devices that communicate using wireless links. These types of networks are growing at the best speed and being used at a large scale than before ever because of their high availability and mobility. As the usage scale of MANET devices has been increasing, the challenges have also increased for example the proper delivery of data or information to every mobile node. Traditionally, transmission control protocol(TCP) is used for delivery but it does not fit in all scenarios due to some of its limitations such as network congestion and quick recovery in case of link failure. In this, a comparative analysis of TCP is performed with the stream control transmission protocol (SCTP) and a TCP variant called TCP VEGAS. A number of ad hoc Scenarios are proposed with varying numbers of mobile nodes,i.e 11,21, and 31. The results obtained indicate that SCTP outperforms TCP and VEGAS in throughput. The packet lifetime while using SCTP is also small i.e 0.19 seconds. The link utilization of SCTP is better than TCP and VEGAS. However, TCP increases its link utilization than VEGAS for the nodes in MANET of large delay.
