Performance Analysis of Wireless Mobile Ad Hoc Network with Different Antennas Using Rayleigh Fading

monika bansal, Laxmi Shrivastava

Abstract


In the context of ad hoc networks, use of directional antenna can largely reduce the radio interference, thereby improving the utilization of wireless medium and consequently the network throughput. Performance of ad hoc networks is low under omni-directional antenna systems compared to smart antenna system when Rayleigh fading model is used. Directional antennas cover large area and transmit large number of packets because it focuses in desired direction accordance with mobility of nodes while omni-directional antennas cover small area and less number of packets as compared to Smart Antenna System (SAS). In this paper, the performance of various parameters by using Smart Antenna Systems (SAS) is analyzed in ad hoc network. The performance parameter include throughput, jitter, end to end delay, and PDR in manet with smart antenna system (SAS) and omni-directional antenna system in different fading environment. Then the comparison of the parameters of omni-directional antenna and directional antennas is done.
