Joint Probing and Scheduling for Cache-Aided Hybrid Satellite-Terrestrial Networks
Zhou Zhang, Yizhu Wang, Saman Atapattu +1
Caching is crucial in hybrid satellite-terrestrial networks to reduce latency, optimize throughput, and improve data availability by storing frequently accessed content closer to u…
Opportunistic Subarray Grouping for RIS-Aided Massive Random Access in Cellular Connectivity
Yizhu Wang, Zhou Zhang, Saman Atapattu +1
In Reconfigurable Intelligent Surfaces (RIS), reflective elements (REs) are typically configured as a single array, but as RE numbers increase, this approach incurs high overhead f…
Throughput Optimization in Cache-aided Networks: An Opportunistic Probing and Scheduling Approach
Zhou Zhang, Saman Atapattu, Yizhu Wang +1
This paper addresses the challenges of throughput optimization in wireless cache-aided cooperative networks. We propose an opportunistic cooperative probing and scheduling strategy…
Dynamic Cooperative MAC Optimization in RSU-Enhanced VANETs: A Distributed Approach
Zhou Zhang, Saman Atapattu, Yizhu Wang +2
This paper presents an optimization approach for cooperative Medium Access Control (MAC) techniques in Vehicular Ad Hoc Networks (VANETs) equipped with Roadside Unit (RSU) to enhan…
