Performance estimation of DSR, DSDV and AODV in TCP, UDP and SCTP

Mobile ad-hoc network is a group of mobile nodes without infrastructure and self-configured in nature. Each node in MANET can move freely in Omni direction thus causes change in links to other devices frequently and they must forward packet transmission irrespective of its personal use; because of this a router is required. So the three prominent routing protocols in MANET such as DSR, AODV and DSDV are considered for the routing in MANETs. In this paper the comparison is based on the performance of two reactive routing protocols DSR, AODV and the proactive DSDV protocol in TCP, UDP and SCTP environments. A simulation model MAC and 802.11 is used to study the interlayer interactions. The performance of protocols is measured based on packet loss and delay. The results are carried out by using network simulator-2. The results presented in this paper illustrate the importance and evaluation of the routing protocols.
