Novel concept of D2D mobility modeling utilizing biological cell jamming/unjamming paradigm

Abstract

The effects of human mobility in Device-to-Device (D2D) communication are not well understood, but with the recent proliferation of D2D, communications have become a critical research emphasis. However, very little is understood on how human mobility and D2D communication are interdependent. The unpredictability of human mobility is one of the root causes in properly visualizing and designing an efficient D2D system framework. The impact of mobility, heterogeneous cell size and distribution, the presence of multiple channel access methods and movement behavior lead to nearly insurmountable challenges in modelling D2D comprehensively and accurately. Thus, to address these challenges our work leverages and extends upon a novel concept from biology and the human mobility model STEPS - that of shape-based cellular jamming and unjamming. Novel and recent studies in the medical domain infer the fundamental reasons for biological cellular jamming as a consequence of distortion in cell shapes. In this paper, a similar analogy of jamming and interaction based distortion in mobility has been used to investigate a novel approach to accurately capture and depict group-based human mobility and its states.
