Offloading Deadline-Constrained Cellular Traffic
Ahmed Ewaisha, Cihan Tepedelenlioglu
In this work we study the problem of hard-deadline constrained data offloading in cellular networks. A single-Base-Station (BS) single-frequency-channel downlink system is studied…
Optimal Power Control and Scheduling for Real-Time and Non-Real-Time Data
Ahmed Ewaisha, Cihan Tepedelenlioglu
We consider a joint scheduling-and-power-allocation problem of a downlink cellular system. The system consists of two groups of users: real-time (RT) and non-real-time (NRT) users.…
Optimal Power Control and Scheduling under Hard Deadline Constraints for Continuous Fading Channels
Ahmed Ewaisha, Cihan Tepedelenlioglu
We consider a joint scheduling-and-power-allocation problem of a downlink cellular system. The system consists of two groups of users: real-time (RT) and non-real-time (NRT) users.…
Power Control and Scheduling under Hard Deadline Constraints for On-Off Fading Channels
Ahmed Ewaisha, Cihan Tepedelenlioglu
We consider the joint scheduling-and-power-allocation problem of a downlink cellular system. The system consists of two groups of users: real-time (RT) and non-real-time (NRT) user…
Throughput Maximization in Multi-Channel Cognitive Radio Systems with Delay Constraints
Ahmed Ewaisha, Cihan Tepedelenlioglu
We study the throughput-vs-delay trade-off in an overlay multi-channel single-secondary-user cognitive radio system. Due to the limited sensing capabilities of the cognitive radio…
Delay Optimal Joint Scheduling-and-Power-Control for Cognitive Radio Uplinks
Ahmed Ewaisha, Cihan Tepedelenlioglu
An uplink cognitive radio system with a single primary user (PU) and multiple secondary users (SUs) is considered. The SUs have an individual average delay constraint and an aggreg…
