Audio streaming for ad hoc wireless mesh networks using network coding
Basil Saeed, Chung–Horng Lung, Thomas Kunz, Anand Srinivasan · 2011
Over the past years, we have witnessed an explosive growth in the use of the multimedia applications such as audio streaming with mobile and static devices. Audio streaming applications demand new approaches to audio transmissions to meet the growing traffic volume, quantity and quality of audio traffic, and users' needs. This paper studies network coding which is a promising paradigm that has the potential to improve the performance of networks for audio streaming applications in terms of packet delivery ratio (PDR), latency and jitter. This paper examines several network coding protocols for ad hoc wireless mesh networks and compares their performances on audio streaming applications with optimized broadcast protocols, e.g., Simplified Multicast Forwarding and Partial Dominant Pruning (PDP). The results show that the performance increases significantly with Random Linear Network Coding (RLNC) scheme.
