Performance Evaluation of MANETs routing protocols for transmitting video

Abstract

Transmitting video over Mobile Ad hoc Networks (MANETs) is the most challenge because of the dynamic of its topology and the mobility of its nodes. These networks operate without a fixed physical infrastructure, allows wireless nodes to seamlessly connect or disconnect at any time. Additionally, the nodes in these networks are capable of self-organization. That makes routing process more difficult than traditional networks in addition to needing high bandwidth requirements to complete video transmitting process. This research investigates and assesses the performance of several commonly utilized standard routing protocols in MANETs, including AODV, DSDV, OLSR, and DSR. The evaluation is conducted across a range of wireless node quantities, spanning from 10 to 100, and tested on many performance metrics such as PDR, ETE delay, Packets Delay Variation (jitter), Data Dropped (DD), Throughput, and routing Overhead, the simulation results are analyzed to determine the most suitable routing protocols among them and overcome the video transmitting. Results shows that OLSR routing protocol is better from others tested protocols in almost performance metrics for video transmitting. Standard routing protocols have many resources constraints that may cause a link failure, when using it in multimedia applications it needs more power consumption and more bandwidth. The performance study simulated with ns3 simulator.
