Comparative Analysis of Routing Protocols And TCP in MANETS
Neha Arora · 2013
Ad hoc networks are characterized by a lack of infrastructure, and by a random and quickly changing network topology; thus the need for a robust dynamic routing protocol that can accommodate such an environment. The paper brings out a comparison among various routing protocols in different scenarios with TCP variants, for their better understanding and implementation. A comprehensive performance evaluation of various routing protocols and the TCP is presented to understand the nature of the TCP performance in different scenarios with variable number of nodes. Three different routing protocols (AODV, TORA and OLSR) have been evaluated with four different TCP variants (Tahoe, Reno, New Reno and SACK) in two different scenarios having 5 and 12 nodes. The performance parameters on the basis of which routing protocols are graded are throughput, delay and congestion window. Conclusions are drawn based on the simulation results and the comparison results are graphically depicted and explained.
