Self-organized follow-me evacuation guidance method using opportunistic networking

Abstract (in Japanese) (See Japanese page) 
(in English) When a wide-scale disaster hits in urban areas, there is a serious problem
to solve how to plan quick evacuation for evacuees to guide to refuge in
order to suppress the confusion of evacuees.
In recent years, we have proposed a method for disaster evacuation guidance
using opportunistic communication.
By simulating this evacuation method using our mathematical model, we have
evaluated the performance and showed that our proposed evacuation can shorten
the evacuation time, and
also contribute to effective disaster information aggregation at refuges.
In the evaluation, however, we have an assumption that all evacuees follow
the guidance.
In this paper, we consider the situation that only some percentage of evacuees
can follow the evacuation. evacuees that follow the guidance form a small group
which is able to absorb evacuees around to follow them, which is called follow-me
guidance.
To simulate the situation, we propose majority voting mobility model to model
evacuees who do not follow the guidance, but they follow to go the direction that
the majority of near evacuees go.
We evaluate the performance of the self-organized follow-me guidance.
As a result, we find that a certain number of leader can absorb the other follower
by the follow-me guidance, which consequently shorten the evacuation time and
increase the number of evacuees arrived at refuge.
Consequently, it is expected that disaster evacuation guidance by smartphone
application plus follow-me evacuation guidance can improve the performance of
the evacuation guidance.
