Towards peer-to-peer sharing of wireless energy services
Crowdsourcing wireless energy services is a novel convenient alternative to
charge IoT devices. We demonstrate peer-to-peer wireless energy services
sharing between smartphones over a distance. Our demo leverages (1) a
service-based technique to share energy services, (2) state-of-the-art power
transfer technology over a distance, and (3) a mobile application to enable
communication between energy providers and consumers. In addition, our
application monitors the charging process between IoT devices to collect a
dataset for further analysis. Moreover, in this demo, we compare the
peer-to-peer energy transfer between two smartphones using different charging
technologies, i.e., cable charging, reveres charging, and wireless charging
over a distance. A set of preliminary experiments has been conducted on a real
collected dataset to analyze and demonstrate the behavior of the current
wireless and traditional charging technologies.Comment: 4 pages, 4 figures. This is an accepted demo paper and it will appear

Mobile Power Network for Ultimate Mobility without Battery Life Anxiety
Similar to the evolution from the wired Internet to mobile Internet (MI), the
growing demand for power delivery anywhere and anytime appeals for power grid
transformation from wired to mobile domain. We propose here the next generation
of power delivery network -- mobile power network (MPN) for wireless power
transfer within a mobile range from several meters to tens of meters. At first,
we present the MPN's concept evolution and application scenarios. Then, we
introduce the MPN's supporting technology, namely resonant beam charging (RBC).
As a long-range wireless power transfer (WPT) method, RBC can safely deliver
multi-Watt power to multiple devices concurrently. Meanwhile, the recent
progress in RBC research has been summarized. Next, we specify the MPN's
architecture to provide the wide-area WPT coverage. Finally, we discuss the
MPN's features and challenges. MPN can enable the ultimate mobility by cutting
the final cord of mobile devices, realizing the "last-mile" mobile power
delivery.Comment: 10 pages, 5 figure
Service-Based Wireless Energy Crowdsourcing
We propose a novel service-based ecosystem to crowdsource wireless energy to
charge IoT devices. We leverage the service paradigm to abstract wireless
energy crowdsourcing from nearby IoT devices as energy services. The proposed
energy services ecosystem offers convenient, ubiquitous, and cost-effective
power access to charge IoT devices. We discuss the impact of a crowdsourced
wireless energy services ecosystem, the building components of the ecosystem,
the energy services composition framework, the challenges, and proposed
solutions.Comment: 15 pages, 7 figures, This is an invited paper and it will appear in

Context-Aware Trustworthy IoT Energy Services Provisioning
We propose an IoT energy service provisioning framework to ensure consumers'
Quality of Experience (QoE). A novel context-aware trust assessment model is
proposed to evaluate the trustworthiness of providers. Our model adapts to the
dynamic nature of energy service providers to maintain QoE by selecting
trustworthy providers. The proposed model evaluates providers' trustworthiness
in various contexts, considering their behavior and energy provisioning
history. Additionally, a trust-adaptive composition technique is presented for
optimal energy allocation. Experimental results demonstrate the effectiveness
and efficiency of the proposed approaches.Comment: 15 pages, 12 figures, This paper is accepted in the 21th
