Abstract
With the recent development of big data technology that collects and analyzes
various data, the technology that continuously collects and analyzes the observed data is
also drawing attention. Moreover, its importance is growing in data collection in areas
where people cannot access. In general, it is not easy to properly deploy IoT wireless
devices for data collection in these areas, and it is also inappropriate to use general wheelbased mobile devices for relocation. Recently, researches have been actively carried out on
hopping moving models in place of wheel-based movement for the inaccessible regions.
The majority of studies, however, so far have unrealistic assumptions that all IoT devices
know the overall state of the network and the current state of each device. Moreover,
various physical terrain environments, such as coarse gravel and sand, can change from
time to time, and it is impossible for all devices to recognize these changes in real-time. In
this paper, with the migration success rate of IoT hopping devices being relocated, the
method of estimating the varying environment is proposed. This method can actively reflect
the changing environment in real-time and is a realistic distributed environment-based
relocation protocol on behalf of non-realistic, theory-based relocation protocols. Also, one
of the significant contributions of this paper is to evaluate its performance using the
OMNeT++ simulation tool for the first time in the world to reflect actual physical
environmental conditions. Compared to previous studies, the proposed protocol was able to
actively reflect the state of the surrounding environment, which resulted in improved
migration success rates and higher energy efficiency.
