Antonious M. Girgis, Amr El-Keyi, Mohammed Nafie, Ramy Gohary
2016 2016 IEEE 84th Vehicular Technology Conference (VTC-Fall)  
In this paper, proactive resource allocation based on user location for point-to-point communication over fading channels is introduced, whereby the source must transmit a packet when the user requests  ...  The source allocates energy to transmit some bits proactively for each time slot of the PW with the objective of reducing the transmission energy over the non-predictive case.  ...  CONCLUSION In this paper, we have proposed proactive scheduling schemes for delay-constrained traffic under two different assumptions on the channel state information at the source.  ...

2016 2016 19th Conference of Open Innovations Association (FRUCT)  
The proposed techniques are evaluated over various traffic rates and their performances are compared with the legacy IEEE 802.15.4 MAC.  ...  The first technique allows nodes to avoid channel deep fade by distributing adaptively their sleep period during their active period according to their channel status.  ...  Besides, when the channel deep fade is detected at the current superframe, the location of the Normal TDMA (NTDMA) period is changed to the end of the next superframe.  ...

Robust link scheduling with channel estimation and location information

L. Srikar Muppirisetty, Rocco Di Taranto, Henk Wymeersch
2013 2013 Asilomar Conference on Signals, Systems and Computers  
We demonstrate that the designed proactive schedulers offer better performance in terms of cost and load, in contrast to a baseline reactive scheduler.  ...  We then present statistical channel models based on location information for cellular and ad-hoc networks.  ...  This is due to the fact that the proactive scheduler exhibits flexibility in scheduling and shifts the loads based on the channel conditions.  ...

Towards URLLC with Proactive HARQ Adaptation [article]

Lam Ngoc Dinh, Ibtissam Labriji, Mickael Maman, Emilio Calvanese Strinati
2022 arXiv   pre-print
Based on Lyapunov stochastic optimization, our adaptation control framework dynamically selects the number of proactive retransmissions for intermittent URLLC traffic scenarios under time-varying channel  ...  We then evaluate the performance of several HARQ strategies and show that our proposal further improves latency over the reactive regime without affecting the resource efficiency such as fixed proactive  ...  This model clarifies the channel behaviours based on antenna modeling, slow-fading factors such as shadowing, propagation loss and fast-fading factors due to multi path.  ...

An Optimal Adaptive Approach using Behavioral Promiscuous Caching and Storage-Capacity Characteristics for Energy Conservation in Asymmetrical Wireless Devices

Constandinos X. Mavromoustakis, Helen D. Karatza
2007 2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications  
In this work, an evaluation scheme is proposed based on each node's self-scheduling energy management.  ...  Current approaches for tuning the energy conservation do not take into consideration the storage requirements of each device, the traffic and channel data rate as well as parameters concerning the caching  ...  This is somehow based on the traversed traffic on the channels. If nodes have low or moderate traffic load, network interfaces are in the idle state most of the time.  ...
