Abstract

“The paper contains the analysis of exposed node problem in mobile adhoc network. The problem is that before starting the transmission, a station wants to know whether there is activity around the receiver. If the transmission is taking place around the receiver, there will be collisions and the effective throughput will be decreased. A detailed study of the simulation on these exposed nodes is carried out using the GloMoSim software to calculate the throughput for the various transmission powers and different protocols, so as to compare the performances by varying different parameters. These simulation results with GloMoSim corroborate our theoretical analysis.”
