Performance Evaluation of Routing Protocols in Live Video Streaming over Wireless Mesh Networks
Behrang Barekatain · Jurnal Teknologi · 2013
In recent years, live video streaming over Wireless Mesh Networks (WMNs) has been of great interest among users. However, node mobility, interferences and competition on the available resources are some important factors, to name a few, which can considerably affect the perceived video quality on wireless nodes. In this regard, employing an efficient routing protocol can address these challenges as much as possible. The fact of the matter is that the real performances of the most recently used routing protocols in live video streaming over WMNs is remaining as an open issue. Therefore, this study design and implement a simulator using the OMNET++ framework and measure the performances of these routing protocols under various and different network conditions based on the different performance metrics. To the best of our knowledge, this is the first study which precisely and comprehensively performs this evaluation. The obtained results not only help interested researchers to select the most appropriate routing protocol for their proposed video streaming applications over WMNs, but also let them introduce more efficient hybrid protocols based on the considered routing protocols in this study
