Video Streaming Application: Image Quality Analysis of Wireless Ad-hoc Network Routing Protocols

Wireless sensor ad-hoc network usually applied in a monitoring system like monitoring temperature, humidity or even any triggering inputs from a connected peripheral device. The approach of wireless ad hoc network for monitoring video data is under preliminary investigation and development because video streaming requires larger storage, quality channel, less jittering and low packet loss. The mobility of IEEE 802.11 in ad-hoc network increases packet loss due to high link breakages. An efficient routing protocol can diagnose, reduce and improves ad-hoc network for video streaming activity. In this paper the Optimized Link State Routing protocol (OLSR), Better Approach To Mobile Ad-hoc Networking protocol (BATMAN) and the Ad-hoc on Demand Distance Vector Routing (AODV) are evaluated in a testbed setup. The Picture Signal to Noise Ratio (PSNR) and the data throughput analysis are the methods employed to measure the quality of video frames captured in wireless ad-hoc video streaming. The AODV are found less durable compared to BATMAN and OLSR because AODV generates packet loss to 20% but rest are 0% to 5%. The PSNR shows that the BATMAN outperforms than other routing protocols but its performance decayed in a mesh network configuration. The BATMAN routing protocol found to be suitable routing protocol is lesser wireless nodes used in an ad-hoc video streaming application.
