ABSTRACT
A wireless ad hoc network is a sovereign system in which users can communicate with each other freely. It can be
deployed rapidly at a very low cost, and can be easily managed and extended. Topology management has main
objective to maintain a topology connectivity that improves wireless network performance by minimizing energy
consumption. Also Topology control with cooperative communication was recently research initiated .Cooperative
Communication (CC) is a technique that allows no. of nodes to simultaneously transmit the same data. It can save
power and extend transmission coverage. Topology management with cooperative communication is new research
initiated in the field of Mobile Ad-hoc Network. In this paper, we analyze the effect of multi-traffic on the
topology managed MANET. We implemented some applications on different mobility models that is OLSR move
and random mobility. To simulate all scenario OPNET 14.5 software is used. OPNET is a comprehensive suite of
tools for modelling large wired and wireless networks. It uses simulation and emulation to predict the behaviour
and performance of networks to improve their design, operation and management.
In the first part of paper, implemented the existed network on the OPNET simulator and evaluate the
performance (Download Response Time, Traffic Send and Traffic Receive) of OLSR move based topology control
network.
In the second part of paper, evaluated the QoS performanc (Delay, Download Response Time, Traffic Send and
Receive Response) of Random Mobility based topology control network. From the simulation results we observed
that compare with OLSR move models, the Random mobility model performance is good. We implemented
different traffic pattern on two Topology managed MANET.
In the third part of paper, implemented the dynamic traffic pattern like Email, FTP & Voice and video
conferencing on the proposed network. Simulation results show that FTP and E-mail both have large download
response time in case of OLSR move model rather than Random Mobility model. Traffic send and receive
performance of email is good in OLSR-move model. Video Conferencing has good response of traffic send and
receive in Random Mobility model.
