Hot topic: physical-layer network coding
TL;DR: This paper proposes a physical-layer network coding (PNC) scheme to coordinate transmissions among nodes that makes use of the additive nature of simultaneously arriving electromagnetic (EM) waves for equivalent coding operation and demonstrates its potential for boosting network capacity.

Journal ArticleDOI
TCP Veno: TCP enhancement for transmission over wireless access networks
Cheng Peng Fu,Soung Chang Liew +1 more
TL;DR: This work proposes and study a novel end-to-end congestion control mechanism called Veno that is simple and effective for dealing with random packet loss in wireless access networks and can achieve significant throughput improvements without adversely affecting other concurrent TCP connections, including other concurrent Reno connections.
Journal ArticleDOI
Channel coding and decoding in a relay system operated with physical-layer network coding
Shengli Zhang,Soung Chang Liew +1 more
TL;DR: This paper redesigns the belief propagation decoding algorithm of the RA code for traditional point-to-point channel to suit the need of the PNC multiple-access channel and shows that the new scheme outperforms the previously proposed schemes significantly in terms of BER without added complexity.

Solutions to performance problems in VoIP over a 802.11 wireless LAN
TL;DR: This paper proposes and investigates a scheme that can improve the VoIP capacity by close to 100% without changing the standard 802.11 CSMA/CA protocol, and shows that VoIP delay and loss performance in WLAN can be compromised severely in the presence of coexisting transmission-control protocol (TCP) traffic.
