  Battery aging is one of the major concerns for the pervasive devices such as
smartphones, wearables and laptops. Current battery aging mitigation approaches
only partially leverage the available options to prolong battery lifetime. In
this regard, we claim that wireless crowd charging via network-wide smart
charging protocols can provide a useful setting for applying battery aging
mitigation. In this paper, for the first time in the state-of-the-art, we
couple the two concepts and we design a fine-grained battery aging model in the
context of wireless crowd charging, and two network-wide protocols to mitigate
battery aging. Our approach directly challenges the related contemporary
research paradigms by (i) taking into account important characteristic
phenomena in the algorithmic modeling process related to fine-grained battery
aging properties, (ii) deploying ubiquitous computing and network-wide
protocols for battery aging mitigation, and (iii) fulfilling the user QoE
expectations with respect to the enjoyment of a longer battery lifetime.
Simulation-based results indicate that the proposed protocols are able to
mitigate battery aging quickly in terms of nearly 46.74-60.87% less reduction
of battery capacity among the crowd, and partially outperform state-of-the-art
protocols in terms of energy balance quality.
