Analysis of Various Routing protocols using Omni directional Antenna in Qual-Net 6.1

Mobile Ad Hoc Networks are formed by devices that are able to communicate with each other using a wireless physical medium without having a route to a preexisting network infrastructure. Omni directional antenna plays a vital role. Omni directional antenna has many advantages such as increased transmission range, higher gain and reduced interference. Omni directional antenna uses a set of elements which has fixed beam nature and radiate the frequency in all directions and also at a specific angle. In this paper we analyse the performance of different Omni directional antennas for different routing protocols such as AODV, OLSR and ZRP. We evaluate analysis based performance comparison of different pause time duration in second The performance analysis is based on different metrics of the application layer such as average jitter, average end to end delay and the basis of physical layer metrics such as power consumed in transmit, receive and idle mode using Qual-Net 6.1.
