Abstract – In todays era, women still feel scared to step out of their homes at late nights due to the fear of sexual harassment. This problem is compounded when one shifts the focus from urban to rural sector and interior areas of villages where there is erratic electric supply and poor cellular network connectivity.This paper proposes a system, by creating a wireless network using IoT technology with a portable device for alerting the concerned authorities to prevent any mishap. Women will be provided with a beacon device consisting of a help button. In case of any emergency, the beacon information will reach the central stations and an alarm will be triggered at the prominent places of the village.

INTRODUCTION

Even though we live in the 21st century with much technological advancement and social awareness, women face the problem of harassment of any form and get abused physically or mentally. Areas like streets and public spaces have been the territory of such violence. This issue worsens for women living in remote and rural areas, where they might not be aware about these crimes or hesitate to report these crimes to the concerned authorities. There are many existing applications and devices for women security through smartphones. Though the smartphones have increased rapidly, it is not possible that the smartphones and cellular network will be available all the times in rural areas. Also, many people in the village do not have smartphones which can assist them in contacting the concerned authorities, otherwise. Literacy rate of villages is low and parents do not send girls to schools due to the fear of sexual harassment.

In this system, women safety is based on BLE (Bluetooth Low Energy) Beacon device due to their low cost, ease of deployment, ease of accessibility to the users and superior interior localization as described in . Kang EunJeon, James She, Perm Soonsawad, and Pai Chet Ng [2] specify that BLE

has low energy requirements and battery life of BLE Beacon devices can be extended upto 2-3 years on a single coin cell battery if broadcast intervals are set appropriately based on the application. BLE is 60 – 80% cheaper than traditional Bluetooth and is compatible with a wide range of IoT(Internet of Things) boards, mobile phones, tablets and computers. It is ideal for the proposed system which requires small periodic broadcast of data at regular interval of 1 – 1.5 seconds.

OBJECTIVES

Objective of this proposal system is in todays era, women still feel scared to step out of their homes at late nights due to the fear of sexual harassment. This problem is compounded when one shifts the focus from urban to rural sector and interior areas of villages where there is erratic electric supply and poor cellular network connectivity.Our Work proposes a system, by creating a wireless network using IoT technology with a portable device for alerting the concerned authorities to prevent any mishap. Women will be provided with a beacon device consisting of a help button. In case of any emergency, the beacon information will reach the central stations and an alarm will be triggered at the prominent places of the village.Multiple solar powered street light poles are arranged in an optimized formation of triangular geometry such that each pole is within the range of its adjacent poles on either side of it. IoT boards [1] will be positioned on these street poles and will be powered using the solar energy taking into account the unpredictable electricity supply to the rural areas. It will act as an Access Point (AP) of the local wireless network through which the ommunicationm between a Beacon device and an AP willoccur. Women will be provided with the Beacon device which will consist of a help button. Based on Beacon devices UUID (Universally Unique Identifier), the user will be identified uniquely and the

Transmission(Tx) Power parameter will enable us to estimate the location of the victim. The AP which sense the maximum Tx Power from the Beacon device will give us the accurate location of thevictim.

For this, the street poles will be identified by a unique identifier and its pre-defined GPS coordinates in the village area. Beacon communication consists primarily of advertise- ment broadcast at a regular interval by Beacon device via radiowaves.

METHODOLOGY

Women will be provided with the Beacon device which will consist of a help button.Based on Beacon devices UUID (Universally Unique Identifier), the user will be identified uniquely and the Transmission (Tx) Power parameter will enable us to estimate the location of thevictim.The AP which sense the maximum Tx Power from the Beacon device will give us the accurate location of thevictim.For this, the street poles will be identified by a unique identifier and its pre- defined GPS coordinates in the villagearea.Beacon communication consists primarily of advertisement broadcast at a regular interval by Beacon device via radiowaves.The communication between a Beacon device and an AP, between any two APs and between an AP and a server at central station is governed by BLE Multi-Hop routing protocol.

ARCHITECTURE

CONCLUSION

In our work, we have proposed a wireless IoT based solution for women safety in rural areas by taking into account two most critical issues of erratic electricity supply and unreliable cellular network which are common in rural areas. To achieve this, solar panels on the street poles power the APs and an independent local network is created based on BLE routing

protocol. Based on the Beacon signal received by an AP, location of the victim is traced out through the RSSI value and supported with a plot on preset map of the village. We introduced multiple central stations so that even if a station fails, the distress message can reach other stations to prevent any mishap.
