Delay-Efficient and Reliable Data Relaying in Ultra Dense Networks using Rateless Codes
Luyao Shang, Morteza Hashemi, Taejoon Kim +1
We investigate the problem of delay-efficient and reliable data delivery in ultra-dense networks (UDNs) that constitute macro base stations (MBSs), small base stations (SBSs), and…
Energy-Aware Multi-Server Mobile Edge Computing: A Deep Reinforcement Learning Approach
Navid Naderializadeh, Morteza Hashemi
We investigate the problem of computation offloading in a mobile edge computing architecture, where multiple energy-constrained users compete to offload their computational tasks t…
Integrating Sub-6 GHz and Millimeter Wave to Combat Blockage: Delay-Optimal Scheduling
Guidan Yao, Morteza Hashemi, Ness B. Shroff
Millimeter wave (mmWave) technologies have the potential to achieve very high data rates, but suffer from intermittent connectivity. In this paper, we provision an architecture to…
Efficient Beam Alignment in Millimeter Wave Systems Using Contextual Bandits
Morteza Hashemi, Ashutosh Sabharwal, C. Emre Koksal +1
In this paper, we investigate the problem of beam alignment in millimeter wave (mmWave) systems, and design an optimal algorithm to reduce the overhead. Specifically, due to direct…
Energy-Efficient Power and Bandwidth Allocation in an Integrated Sub-6 GHz -- Millimeter Wave System
Morteza Hashemi, C. Emre Koksal, Ness B. Shroff
In mobile millimeter wave (mmWave) systems, energy is a scarce resource due to the large losses in the channel and high energy usage by analog-to-digital converters (ADC), which sc…
Reducing ADC Sampling Rate with Compressive Sensing
Morteza Hashemi
Many communication systems involve high bandwidth, while sparse, radio frequency (RF) signals. Working with high frequency signals requires appropriate system-level components such…
