Seminar on Mobile Ad hoc Network

Introduction to Seminar on Mobile Ad hoc Network:

With the increase in demand towards wireless networks there are many models introduced in this context. The key among them are MANETs (Mobile Adhoc Networks) and WSN (Wireless Sensor Networks) and the level of wireless operations are sophisticated across these networks. The range of application usage across the MANETs also has increased.

The main issue with the usage of applications across the MANETs is to provide the required levels of quality of service to the applications as the MANETS are infrastructure less networks. When it comes to the case of voice and video applications, the range of quality of service requirement is more and it is always important to provide the same across the wireless networks like MANETs. In general the voice and video application suffers with packet delays and streaming quality.

The main aim of this project is to improve the quality of service for the voice and video applications across the MANETs. In general the overall behaviour of any wireless networks mainly depends on the corresponding routing protocols and the key routing process implemented. The behavior of the applications and the corresponding quality of service requirements also depends on these routing protocols.

To improve the overall quality of the video and voice applications across MANETs, a total of 6 scenarios are created in this project. A MANET with 20 mobile nodes and a wireless LAN server is created in this project using OPNET Modeler tool. The actual simulation procedure followed in this context is explained in the previous chapters. Three scenarios are created for IP telephony voice application against three routing protocols like AODV, DSR and TORA and similar scenarios are created for video applications. The key performance metrics for voice application like Jitter, MOS, packet delay variation and packet end to end delay are used to evaluate the QoS requirements and for the video application the performance metrics like packet delay variation and packet end to end delay are used. All the six scenarios are run to achieve the results. From the overall analysis of the results it is clear that the quality of service of both the voice and video applications can be enhanced using the AODV routing protocol.

The reactive nature of this protocol is useful in providing the ample quality of service requirements for voice and video applications and thus implementing the AODV routing protocol will enhance the overall quality of the applications across the wireless networks like MANETs.
