Asymptotically optimal policies for wireless networks with rechargeable batteries
Gatzianas, M.; Georgiadis, L.; Tassiulas, L. (2008)We consider the problem of cross-layer resource allocation for single-hop, time-varying, wireless networks operating with rechargeable batteries under general arrival, channel and recharge processes. The objective is to ... -
Capacity-achieving encoding for the broadcast erasure channel with multiple users
Gatzianas, M.; Georgiadis, L.; Tassiulas, L. (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 ... -
Control of Wireless Networks with Rechargeable Batteries
Gatzianas, M.; Georgiadis, L.; Tassiulas, L. (2010)We consider the problem of cross-layer resource allocation for wireless networks operating with rechargeable batteries under general arrival, channel state and recharge processes. The objective is to maximize total system ... -
Multiuser Broadcast Erasure Channel With Feedback-Capacity and Algorithms
Gatzianas, M.; Georgiadis, L.; Tassiulas, L. (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 ... -
XOR-Based Encoding With Instantaneous Decoding for the Broadcast Erasure Channel With Feedback: The Three-User Case
Athanasiadou, S.; Gatzianas, M.; Georgiadis, L.; Tassiulas, L. (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 ...
