Journal ArticleDOI
Transmitting data on the phase of speech signals
TL;DR: A method for embedding data into speech signals without recourse to bandwidth expansion is proposed, and the unvoiced sounds were perceived with negligible distortion owing to the preservation of their magnitude spectra.
Proceedings ArticleDOI
Secure wireless communication platform for EV-to-Grid research
TL;DR: The authentication protocol for secure wireless communications between the Aggregators and EVs is addressed and shows that it can securely protect the exchanged information with less overhead and less authentication latency.
Proceedings ArticleDOI
CR-WSN MAC: An energy efficient and spectrum aware MAC protocol for cognitive radio sensor network
TL;DR: A novel energy-efficient and spectrum aware multi-channel medium access control (MAC) protocol for the underlying cognitive radio enabled sensor network and designed a spectrum aware asynchronous duty cycle approach which caters to the requirements of both the domains.
Proceedings ArticleDOI
A lightweight inter-user interference mitigation method in Body Sensor Networks
Wen Sun,Yu Ge,Wai-Choong Wong +2 more
TL;DR: An inter-user interference mitigation mitigation (IIM) method is presented, which enables BSNs to adaptively reschedule their transmissions or switch to another channel in a distributed manner based on the detected information from neighboring BSBs.
Journal ArticleDOI
A context realization framework for ubiquitous applications with runtime support
TL;DR: An application context model (ACM) is proposed for developers to specify their requirements on the context-related tasks and the experimental results based on the system prototype are presented.
