Joint Task Offloading and Resource Allocation for IoT Edge Computing with Sequential Task Dependency
Xuming An, Rongfei Fan, Han Hu +3
Incorporating mobile edge computing (MEC) in the Internet of Things (IoT) enables resource-limited IoT devices to offload their computation tasks to a nearby edge server. In this p…
Relay Assisted Underlay Cognitive Radio Networks with Multiple Users
Lanwei Zhang, Rajitha Senanayake, Saman Atapattu +1
In this letter, we consider an underlay cognitive radio network assisted by dual-hop decode-and-forward (DF) relaying. For a general multi-user network, we adopt a max-min fairness…
Performance Analysis of a Two-Tile Reconfigurable Intelligent Surface Assisted MIMO System
Prathapasinghe Dharmawansa, Saman Atapattu, Marco Di Renzo
We consider a two--tile reconfigurable intelligent surface (RIS) assisted wireless network with a two-antenna transmitter and receiver over Rayleigh fading. We show that the averag…
Latency Minimization with Optimum Workload Distribution and Power Control for Fog Computing
Saman Atapattu, Chathuranga Weeraddana, Minhua Ding +2
This paper investigates a three-layer IoT-fog-cloud computing system to determine the optimum workload and power allocation at each layer. The objective is to minimize maximum per-…
Reconfigurable Intelligent Surface assisted Two-Way Communications: Performance Analysis and Optimization
Saman Atapattu, Rongfei Fan, Prathapasinghe Dharmawansa +3
In this paper, we investigate the two-way communication between two users assisted by a re-configurable intelligent surface (RIS). The scheme that two users communicate simultaneou…
Resource Allocation in Dynamic DF Relay for SWIPT Network with Circuit Power Consumption
Bhathiya Pilanawithana, Saman Atapattu, Jamie Evans
This paper considers simultaneous wireless information and power transfer (SWIPT) over a dual-hop dynamic decode-and-forward (DF) relay network with the power-splitting (PS) energy…
