An Experimental Evaluation of Packet Aggregation and Network Coding for Multi-hop VoIP Transport

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we present an experimental evaluation of bidirectional packet aggregation and coding (BiPAC),
a packet mixing technique which jointly applies packet aggregation and
network coding in order to increase the number of supportable VoIP sessions in wireless multi-hop networks.
BiPAC applies network coding for aggregated VoIP packets by exploiting bidirectional nature of VoIP sessions,
and largely reduces the required protocol overhead for transmitting short VoIP packets.
We implement BiPAC in a wireless testbed, and run experiments in an actual indoor environment.
Our experimental results show that BiPAC is a practical and efficient forwarding method,
which can be implemented into the current mesh hardware and network stack.
