Effect of Mobility and Traffic Pattern on MANET Routing Protocols  
  Authors : Dr. Sharaf A. Alhomdy; Ali A. Abo-Alregal

 

Mobile Ad-hoc networks (MANETs) are selforganizing networks which can form a communication network without any fixed infrastructure. Recently, MANET has gained popularity in many different applications having different mobility models and traffic patterns. There are several traffic patterns such as Exponential Probability Distribution, Pareto Probability Distribution, and Constant Bit Rate (CBR). The traffic pattern and number of nodes are plays an important role in the performance of a routing protocol. This paper will assess the performance of mobility models and traffic patterns for three routing protocols which are Reactive (AODV), Proactive (OLSR) and hybrid (TORA) for different traffic generators CBR, Exponential and Pareto traffic patterns with Random Way Point mobility model using different number of nodes. The performance of these routing protocols is analyzed with respect to three parameters that are packet drop, throughput and End-to-End Delay conducted using OPNET simulator. The conducted results show good ranking of routing protocols depending on both mobility models and traffic patterns.

In the recent years, MANETs have gained the popularity in many various applications having different mobility models and traffic patterns. The traffics patterns play an important role in the performance of routing protocols. In this paper, the traffic model determines the performance analysis of three routing protocols (AODV, OLSR and TORA) with different traffic patterns. The simulation results observed that the performance of AODV routing protocol in terms of throughput is better with CBR traffic model. Whereas, in case of packet drop the Exponential traffic model gives the good performance for AODV. Also PARETO traffic model is the good choice for End-to-End delay metric to enhance performance of AODV. Therefore, the results show that AODV routing protocol performs better in CBR, PARETO and EXPONENTIAL traffic patterns in terms of throughput and end-to-end delay compared to the other two protocols. In general, the conducted results show that the good ranking of routing protocols depending on both mobility models and traffic patterns. Future work will extend the study on more routing protocols.
