Scheduling with pairwise XORing of packets under statistical overhearing information and feedback
(2012)
We study the problem of scheduling packets from several flows traversing a given node which can mix packets belonging to different flows. Practical wireless network coding solutions depend on knowledge of overhearing events ...
Wireless network coding with partial overhearing information
(2013)
We study an 1-hop broadcast channel with two receivers. Due to overhearing channels, the receivers have side information which can be leveraged by interflow network coding techniques to provide throughput increase. In this ...
A modular framework for implementing joint wireless network coding and scheduling algorithms
(2013)
Intersession network coding (NC) can provide significant performance benefits via mixing packets at wireless routers; these benefits are especially pronounced when NC is applied in conjunction with intelligent scheduling. ...
XOR-Based Encoding With Instantaneous Decoding for the Broadcast Erasure Channel With Feedback: The Three-User Case
(2014)
We study the case of a three-user broadcast erasure channel with multiple unicast traffic sessions, where feedback from the users is fed back to the transmitter in the form of positive acknowledgment (ACK)/negative ...
Capacity-achieving encoding for the broadcast erasure channel with multiple users
(2011)
We consider the N-user memoryless broadcast erasure channel with N unicast sessions (one for each user) where receiver feedback is sent to the transmitter in the form of ACK/NACK messages. We first provide a generic outer ...
The mutual benefits of primary-secondary user cooperation in wireless cognitive networks
(2014)
In cognitive radio networks, secondary users (SUs) may cooperate with the primary user (PU) in order to obtain more transmission opportunities and thus maximize their throughput. The synergy consists in the following: the ...
Multiuser Broadcast Erasure Channel With Feedback-Capacity and Algorithms
(2013)
We consider the N-user broadcast erasure channel with unicast sessions (one for each user) where receiver feedback is regularly sent to the transmitter in the form of ACK/NACK messages. We first provide a generic outer ...
Capacity and Stable Throughput Regions for the Broadcast Erasure Channel With Feedback: An Unusual Union
(2013)
We consider a source node broadcasting to two receivers over a general erasure channel with receiver feedback. We characterize the capacity region of the channel and construct algorithms based on linear network coding ...
Minimal Evacuation Times and Stability
(2015)
We consider a system where packets (jobs) arrive for processing using one of the policies in a given class. We study the connection between the minimal evacuation time and the stability region of the system and show that ...
Dynamic Wireless Network Coding With Overhearing and Variable Channel Rates
(2015)
We study a one-hop broadcast channel with two receivers. The receivers have side information obtained by overhearing wireless channels. The relay takes control decisions by coding transmissions based on its knowledge of ...
