Opportunistic Scheduling of Randomly Coded Multicast Transmissions at Half-Duplex Relay Stations

Chao Chen, Seung Jun Baek, Gustavo de Veciana
2016 IEEE Transactions on Information Theory  
We consider the multicast scheduling problem for block transmission of packets in a heterogeneous network using a half-duplex Relay Station (RS).  ...  Because of the half-duplex operation, at each time slot the RS must decide to either (1) fetch a new packet for encoding from the base station, or (2) multicast a coded packet to mobile users.  ...  At each time slot, the half-duplex RS can either fetch an original packet from the BS or multicast a coded packet to the users.  ...

Cross-layer bandwidth management and optimization in TDMA based wireless mesh networks using network coding

Parag S. Mogre
2010 ACM SIGMultimedia Records  
A common feature of these standards is the use of Time Division Multiple Access/Time Division Duplex (TDMA/TDD) for supporting QoS, by enabling the explicit reservation of bandwidth for data transmissions  ...  SONC makes network coding decisions and performs network coding operations at the granularity of streams.  ...  This leads to a significantly increased number of network coding opportunities using HeNear, especially in the AccNet scenario.  ...

Generalized Instantly Decodable Network Coding for relay-assisted networks

Adel M. Elmahdy, Sameh Sorour, Karim G. Seddik
2013 2013 IEEE 24th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC)  
In this paper, we investigate the problem of minimizing the frame completion delay for Instantly Decodable Network Coding (IDNC) in relay-assisted wireless multicast networks.  ...  This use of generalized IDNC is supported by showing that it is a super-set of the strict IDNC scheme, and thus can generate coding combinations that are at least as efficient as strict IDNC in reducing  ...  RNs operate in half-duplex mode and cannot transmit simultaneously with the BS, even if they have received all the packets in N .  ...

Physical-Layer Network Coding: Tutorial, Survey, and Beyond [article]

Soung Chang Liew, Shengli Zhang, Lu Lu
2011 arXiv   pre-print
The concept of physical-layer network coding (PNC) was proposed in 2006 for application in wireless networks. Since then it has developed into a subfield of network coding with wide followings.  ...  The basic idea of PNC is to exploit the network coding operation that occurs naturally when electromagnetic (EM) waves are superimposed on one another.  ...  This work was also partially supported by NSF of China (Project No. 60902016) and NSF of Guangdong (Project No. 10151806001000003).  ...
