Performance analysis of propagation structures on DSR routing protocol in mobile ad-hoc networks

Propagation structure has a vital role in designing the Mobile ad-hoc networks (MANETs). Propagation structure is employed for computing signal strength about each data packet at the destination. Propagation Structures in MANETs are characterized into three categories such as Free Space structure, Two-Ray Ground structure and Shadowing structure. Here in this paper, the effect of Two-Ray Ground propagation structure and Shadowing propagation structure on the performance of DSR routing protocol is conferred. Propagation Structure has a great impact on the simulation results. The simulation is accomplished using NS 2 simulator and the various Performance Attributes used for the evaluation of the performance of DSR protocol are Average Delay, Packet Delivery Ratio, Energy Consumption and Throughput.
