QoS Performance Analysis of Some Routing Protocols in MANET

Mobile Ad Hoc Network (MANET) is introduced for vital situations where the infrastructure or wireless networks fails to provide a connectiOD. during natural disasters and wars. This is because MANET is an independent network that relies on its own battery power for routing packets. In this paper, we eumined the Quality of Service (Q) parameters for two types of routing protocols; namely reactive and proactive protocols. In this study, we bandied the Ad Hoc On-Demand Distance Vector (AODV) and Dynamic Source Routing (DSR) protocols as the reactive protocols. On the other hand, we used the Destination­ Sequenced Distance Vector (DSDV) and Optimized Link State Routing (OLSR) protocols as the proactive protocols. We considered the throughput, end-te>-end delay and packet delivery ratio as the Q parameters. We carried out dift'erent scenarios where the network area size, network density, speed, and pause time were changed. We run the NS2 simulator to execute the performance of these scenarios through some numerical results.
