Flowshop Machine Scheduling: Markov Modeling, Optimal Schedules and Heuristics
Samah A. M. Ghanem
Flowshop machine scheduling has been of main interest in several applications where the timing of its processes plays a fundamental role in the utilization of system resources. Add…
Network Coding Power Control Mechanisms for Time Varying Channels
Samah A. M. Ghanem
In this paper, we propose a model for large scale fading channels via markov process. We exploit the channel delay profile and the dependency between channel states via a first ord…
Information Theoretic I-MMSE generalize Time-Frequency Signal Processing Tools
Samah A. M. Ghanem
In this paper, we capitalize on information theoretic-estimation theoretic result, called the I-MMSE [1]-[2] to show that such tool generalizes time-frequency signal processing too…
MIMO Mutli-Cell Processing: Optimal Precoding and Power Allocation
Samah A. M. Ghanem
We investigate the optimal power allocation and optimal precoding for a cluster of two BSs which cooperate to jointly maximize the achievable rate for two users connecting to each…
Network Coded Handover in IEEE 802.11
Samah A. M. Ghanem
We propose a network coded handover of a station moving between two IEEE 802.11 access points (AP). To address such novel proposed framework on a small cell WiFi to WiFi AP handoff…
Piggybacking Codes for Network Coding: The High/Low SNR Regime
Samah A. M. Ghanem
We propose a piggybacking scheme for network coding where strong source inputs piggyback the weaker ones, a scheme necessary and sufficient to achieve the cut-set upper bound at hi…
