Pulse Shape-Aided Multipath Delay Estimation for Fine-Grained WiFi Sensing
Ke Xu, He Chen, Chenshu Wu
Due to the finite bandwidth of practical wireless systems, one multipath component can manifest itself as a discrete pulse consisting of multiple taps in the digital delay domain.…
Age of Information in Reservation Multi-Access Networks with Stochastic Arrivals: Analysis and Optimization
Qian Wang, He Chen
This paper analyzes and optimizes the average Age of Information (AAoI) of Frame Slotted ALOHA with Reservation and Data slots (FSA-RD) in a multi-access network, where multiple us…
A Just-In-Time Networking Framework for Minimizing Request-Response Latency of Wireless Time-Sensitive Applications
Lihao Zhang, Soung Chang Liew, He Chen
This paper puts forth a networking paradigm, referred to as just-in-time (JIT) communication, to support client-server applications with stringent request-response latency requirem…
Optimizing Information Freshness for Cooperative IoT Systems with Stochastic Arrivals
Bohai Li, Qian Wang, He Chen +2
This paper considers a cooperative Internet of Things (IoT) system with a source aiming to transmit randomly generated status updates to a designated destination as timely as possi…
Partially Observable Minimum-Age Scheduling: The Greedy Policy
Yulin Shao, Qi Cao, Soung Chang Liew +1
This paper studies the minimum-age scheduling problem in a wireless sensor network where an access point (AP) monitors the state of an object via a set of sensors. The freshness of…
Optimizing Information Freshness via Multiuser Scheduling with Adaptive NOMA/OMA
Qian Wang, He Chen, Changhong Zhao +3
This paper considers a wireless network with a base station (BS) conducting timely status updates to multiple clients via adaptive non-orthogonal multiple access (NOMA)/orthogonal…
