performance. The time delay for connecting
between the unsafe and safe zone is very minimum like 10-14 seconds, which is very minimal
compared to the existing delay. This delay is due
to the discover process of unsafe zone users. It
means that the system is capable of managing
the huge number of users with the same scalable.
There are 1,000 nodes are grouped in every
range. The system scalability is not degraded.
The proposed system is providing the same performance when number unsafe user ratios are
increasing.

CONCLUSION
The tailored D2D technique can provide safety
support and emergency service for the mobile
users before and after disasters. It is validated in
various angles and situations. This technology can
also use BS in place of the existing cellular communication. There are upgraded softwares which are
hybrid with wireless network and ad-hoc routing
protocols for collecting, monitoring, and accessing the local details of the mobile user. The technology can provide fault tolerance, high reliability,
and effective service to all mobile users.
